PREFACE.


    A puzzle is not solved, impatient sirs,
    By peeping at its answer in a trice:
    When Gordius, the ploughboy King of Phrygia,
    Tied up his implements of husbandry
    In the far-famed knot, rash Alexander
    Did not undo by cutting it in twain.

It is hoped that this little book may prove useful, not only in
connection with puzzles for home amusement, but that by inducing
people to consider the various difficulties met with in business and
trade some at least may be led to greater success in dealing with the
practical puzzles and problems of everyday life.

It is the special desire of the author to produce a “sugar-coated
mathematical pill,” as he feels convinced that many can more easily
grasp the truth when it is put before them in a light manner than
when brought forward in the usual orthodox fashion.

No pains have been spared to make the PUZZLE KING the best
of its kind yet produced, and the author here wishes to thank his
many friends who have so kindly assisted him. It would be well-nigh
impossible to individualize; but especial thanks are due to Thos.
Finney, Esq., M.L.A. (Brisbane), for the interest he has manifested
throughout, and the kindly help he has so often rendered the author.

It might afford our readers some pleasure to know that this work
is entirely Australian. The printers, artist, and author are all
colonial-born, and the production of the former two, at any rate,
will compare favourably with that of any others.

The engravings throughout have been in the hands of Mr. Murray Fraser
and staff, whose experience in this special art has tended to make
the book more attractive than it otherwise would have been.

The author is not above receiving any suggestions or contributions in
the way of peculiar puzzles or commercial comicalities, which might
enhance the value of the book. Intending contributors are invited
to communicate to the address given below, and can rest assured
that they will be remunerated according to the merits of their
communications.

READING BIG NUMBERS.

Wonderful Calculations.


Although we are accustomed to speak in the most airy fashion of
millions, billions, &c., and “rattle” off at a breath strings of
figures, the fact still remains that we are unable to grasp their
vastness. Man is finite--numbers are infinite!

                        ONE MILLION

Is beyond our conception. We can no more realise its immensity, than
we can the tenth part of a second. It should be a pleasing fact
to note that commercial calculations do not often extend beyond
millions; generally speaking, it is in the realm of speculative
calculation only, such as probability, astronomy, &c., that we are
brought face to face with these unthinkable magnitudes.

Who, for instance, could form the slightest idea that the odds
against a person tossing a coin in the air so as to bring a head
200 times in succession are
160693804425899027554196209234116260522202993782792835301375
(over I decillion, &c.) to 1 against him? Suppose that all the men,
women and children on the face of the earth were to keep on tossing
coins at the rate of a million a second for a million years, the
odds would still be too great for us to realise against any one
person succeeding in performing the above feat, and yet the number
representing the odds would be only half as long as the one already
given.

Or, who could understand the other equally astounding fact that
Sirius, the Dog-star, is 130435000000000 miles from the earth, or
even that the earth itself is 5426000000000000000000 tons in weight.

                     WHAT IS A BILLION

In Europe and America, the billion is 1,000,000,000--a thousand
millions--but in Great Britain and her Colonies, a billion is
reckoned 1,000,000,000,000--a million millions: a difference which
should perhaps be worth remembering in the case of francs and dollars.

One billion sovereigns placed side by side would extend to a distance
of over 18,000,000 miles, and make a band which would pass 736 times
round the globe, or, if lying side by side, would form a golden belt
around it over 26 ft. wide; if the sovereigns were placed on top of
each other flatways, the golden column would be more than a million
miles in height.

Supposing you could count at the rate of 200 a minute; then, in
one hour, you could count 12,000--if you were not interrupted. Well,
12,000 an hour would be 288,000 a day; and a year, or 365 days,
would produce 105,120,000. But this would not allow you a single
moment for sleep, or for any other business whatever. If Adam at
the beginning of his existence, had begun to count, had continued to
count, and were counting still, he would not even now, according to
the usually supposed age of man, have counted nearly enough. To
count a billion, he would require 9,512 years, 342 days, 5 hours and 20
minutes, according to the above reckoning. But suppose we were to
allow the poor counter twelve hours daily for rest, eating and sleeping,
he would need 19,025 years, 319 days, 10 hours and 40 minutes to
count one billion.

  A comparison--
         One million seconds = less than 12 days
          "  billion    "    = over 31,000 years


A GOOD CATCH.

1.--Ask a person to write, in figures, eleven thousand, eleven
hundred and eleven. This often proves very amusing, few being able to
write it correctly at first.

2.--If the eighth of £1 be 3s, what will the fifth of a £5 note be?


=BOTHERSOME BILLS=.

Defter at the anvil than at the desk was a village blacksmith who
held a customer responsible for a little account running:

         Totle of altigether                 5 shillins and fippunse.

That the honest man’s services had been requisitioned for the mending
of two saucepans, putting a new handle to an old cleaver, sharpening
three blunted iron skewers, repairing a lantern, and providing a bell
with a clapper is clear enough; and by resolving “a fillup” into “A.
Phillip,” all obscurity is removed from the last two items, but “the
numoraman a bad i” is a nut the reader must crack for himself.


ONE FROM A PUBLICAN.

He stabled a horse for a night, and sent it home next day with a bill
debiting the owner:

                      To anos              4/6

                                           5/-


A LAUNDRY BILL.

A tourist in Tasmania, being called upon to pay a native dame of the
wash-tub “OOo III,” opened his eyes and ejaculated, “O!” but the good
woman explained that he owed her just two and ninepence, a big O
standing for a shilling, a little one for sixpence, and each I for a
penny.


THE DUTCHMAN’S ACCOUNT.

                       Two wax dolls      15/-

The two dolls were 7s 6d each, but one “wouldn’t do;” so, being
returned, it was taken off the account in the above manner.

QUITE RIGHT.

At a large manufactory a patent pump refused to work. Several
engineers failed to discover the cause. The local plumber, however,
succeeded, after a few minutes, in putting it in working order, and
sent to the company--

3. What is the number that the square of its half is equal to the
number reversed?


HOW TO GET A HEAD-ACHE.

[Illustration]

Naturalists state that snakes, when in danger, have been known to
swallow each other; the above three snakes have just commenced to
perform this operation. The snakes are from the same “hatch,” and
are therefore equal in age, length, weight, &c. They all start at
scratch--that is, commence swallowing simultaneously. They are
twirling round at the express rate of 300 revolutions per minute,
during which time the circumference is decreased by 1 inch.

We would like our readers to tell us what will be the final result?
Heads or tails, and how many of each?


4. A man sold two horses for £100 each; he lost 25 per cent. on one,
and gained 25 per cent. on the other. Was he “quits”; or did he lose
or gain by the transaction; and, if so, how much?


A GOOD CARD TRICK.

The performer lays upon the table ten cards, side by side, face
downwards. Anyone is then at liberty (the performer meanwhile
retiring from the room) to shift any number of the cards (from one
to nine inclusive) from the right hand end of the row to the left,
but retaining the order of the cards so shifted. The performer, on
his return, makes a little speech: “Ladies and gentlemen, you have
shifted a certain number of these cards. Now, I don’t intend to ask
you a single question. By a simple mental calculation I can ascertain
the number you have moved, and by my clairvoyant faculty, though the
cards are face downwards, I shall pick out one corresponding with
that number. Let me see” (pretends to calculate, and presently turns
up a card representing “five”). “You shifted five cards and I have
turned up a five, the exact number.”

The cards moved are not replaced, but the performer again retires,
and a second person is invited to move a few more from right to
left. Again the performer on his return takes up the correct card
indicating the number shifted. The trick, unlike most others, may be
repeated without fear of detection.

[Illustration]

The principle is arithmetical. To begin with, the cards are arranged,
unknown to the spectators, in the following order:

Ten, nine, eight, seven, six, five, four, three, two, one.

Such being the case, it will be found that, however many are shifted
from right to left, the _first_ card of the new row will indicate
their number. Thus, suppose _three_ are shifted. The new order of the
cards will then be:

_Three_, two, one, ten, nine, eight, seven, six, five, four.

So far, the trick is easy enough, but the method of its continuance
is a trifle more complicated. To tell the position of the indicating
card after the second removal, the performer privately adds the
number of that last turned up (in this case _three_) to its place in
the row--_one_. That gives us _four_, the card to be turned up
after the next shift will be the fourth. Thus, suppose six cards are now
shifted, their new order will be:

Nine, eight, seven, _six_, five, four, three, two, one, ten.

Had five cards only been shifted, the _five_ would have been
fourth in the row, and so on.

The performer now adds _six_, the number of the card, to its place
in the row, _four_: the total, _ten_, gives him the position of
the indicator for the next attempt. Thus, suppose four cards are next
shifted, the new order will be:

Three, two, one, ten, nine, eight, seven, six, five, _four_.

The next calculation, 4 and 10, gives us a total 14. The ten is, in
this case, cancelled, and the fourteen regarded as _four_, which
will be found to be the correct indicator for the next shifting.

It looks more mystifying if the performer be blindfolded, for he can
tell the position of the cards with his fingers. Keeping his hand
on the card, he asks, “Will you please tell me how many cards were
shifted?” As soon as the answer is given, he exhibits the card, and
can continue the trick as long as he pleases.


5. Find 16 numbers in arithmetical progression (common difference 2)
whose sum shall be equal to 7552, and arrange them in 4 columns, 4
numbers in each column--or, in other words, arrange in a square of 16
numbers that when added vertically, horizontally, or diagonally, the
sum of each 4 numbers will amount to 1888.




SOME CURIOUS NUMBERS.


If the number 37 be multiplied by 3, or any multiple of 3 up to 27,
the product is expressed by three similar digits. Thus--

                            37 × 3 = 111
                            37 × 6 = 222
                            37 × 9 = 333

The products succeed each other in the order of the digits read
downwards, 1, 2, 3, etc., these being multiplied by 3 (their number
of places) reproduce the multiplicand of 37.

                              1 × 3 = 3
                              2 × 3 = 6
                              3 × 3 = 9

If it be multiplied by multiples of 3, beyond 27, this peculiarity is
continued, except that the extreme figures taken together represent
the multiple of 3 that is used as a multiplier. Thus--

                 37 × 30 = 1110, extreme figures, 10
                 37 × 33 = 1221     "       "     11
                 37 × 36 = 1332     "       "     12

The number 73 (which is 37 inverted) multiplied by each of the
numbers of arithmetical progression 3, 6, 9, 12, 15, etc., produces
products terminating (unit’s place) by one of the ten different
figures, 1, 2, 3, 4, 5, 6, 7, 8, 9, 0. These figures will be found in
the reverse order to that of the progression, 73 × 3 produces 9, by 6
produces 8, and 9 produces 7, and so on.

Another number which falls under some mysterious law of series is
142,857, which, multiplied by 1, 2, 3, 4, 5, or 6 gives the same
figures in the same order, beginning differently; but if multiplied
by 7, gives all 9’s.

                  142,857 multiplied by 1 = 142,857
                   "         "        2 = 285,714
                   "         "        3 = 428,571
                   "         "        4 = 571,428
                   "         "        5 = 714,285
                   "         "        6 = 857,142
                   "         "        7 = 999,999

Multiplied by 8, it gives 1,142,856, the first figure added to the
last makes the original number--142,857.

The vulgar fraction 1/7 = ·142,857.

The following number, 526315789473684210, if multiplied as above,
will, in the product, present the same peculiarities, as also will
the number 3448275862068965517241379310.

        The multiplication of 987654321 by 45 = 444444444445
              Do.             123456789 "  45 =   5555555505
              Do.             987654321 "  54 =  53333333334
              Do.             123456789 "  54 =   6666666606

Taking the same multiplicand and multiplying by 27 (half 54) the
product is 26,666,666,667, all 6’s except the extremes, which read
the original multiplier (27). If 72 be used as a multiplier, a
similar series of progression is produced.


6. In stables five, can you contrive to put in horses twenty--
   In each stable an odd horse, and not a stable empty?


“THREE THREES ARE TEN.”

This little trick often puzzles many:--

Place three matches, coins, or other articles on the table, and by
picking each one up and placing it back three times, counting each
time to finish with number 10, instead of 9. Pick up the first match
and return it to the table saying 1; the same with the second and
third, saying 2 and 3; repeat this counting 4; but the fifth match
must be held in the hand, saying at the time it is picked up, 5; the
other two are also picked up and held in hand, making 6 and 7; the
three matches are then returned to the table as 8, 9, and 10. If done
quickly few are able to see through it.


7. A man bought a colt for a certain sum and sold him 2 years
afterwards for £50 14s., gaining thereby as much per cent. per annum
compound interest as it had cost him. What was the original price?


=Do Figures Lie?=


“Figures cannot lie,” is a very old saying. Nevertheless, we can
all be deceived by them. Perhaps one of the best instances of them
leading us astray is the following:--

An employer engaged two young men, A and B, and agreed to pay them
wages at the rate of £100 per annum. A enquires if there is to be a
“rise,” and is answered by the employer, “Yes, I will increase your
wages £5 every six months.” “Oh! that is very small; it’s only £10
per year,” replied A. “Well,” said the employer, “I will double it,
and give you a rise of £20 per year.” A accepts the situation on
those terms.

B, in making his choice, prefers the £5 every six months. At the
first glance, it would appear that A’s position was the better.

Now, let us see how much each receives up to the end of four years:--

           A                 B
  1st year   £100   |    50}    1st year
  2nd  "      120   |    55}
  3rd  "      140   |    60}    2nd  "
  4th  "      160   |    65}
                    |    70}    3rd  "
                    |    75}
                    |    80}    4th  "
                    |    85}
             ----   |  ----
             £520   |  £540


A spieler at a Country Show amused the people with the following
game:--He had 6 large dice, each of which was marked only on one
face--the first with 1, the second 2, and so on to the sixth, which
was marked 6. He held in his hand a bundle of notes, and offered to
stake £100 to £1 if, in throwing these six dice, the six marked faces
should come up only once, and the person attempting it to have 20
throws.

Though the proposal of the spieler does not on the first view appear
very disadvantageous to those who wagered with him, it is certain
there were a great many chances against them.

The six dice can come up 46,656 different ways, only one of which
would give the marked faces; the odds, therefore, in doing this
in one throw would be 46,655 to 1 against, but, as the player was
allowed 20 throws, the probability of his succeeding would be--

                                 20
                               ------
                               46,656

To play an equal game, therefore, the spieler should have engaged to
return 2332 times the money deposited.


TREBLE RULE OF THREE.

MAGIC ADDITION.

_To write the answer of an addition sum, when only one line has been
written._

Tell a person to write down a row of figures. Now, this row will
constitute the main body of the answer. Tell him to write another
row beneath it; you now write a row also, matching his second row in
pairs of 9’s he writes one more row, and you again supply another in
the same manner. Your addition sum will now consist of five lines,
four of which are paired; the first line, or _key_ line, being the
answer to the sum.

From the unit figure in the _key_ line deduct the number of pairs of
9’s--in this instance two--and place the remainder, 6, as the unit
figure of the answer, then write in order the rest of the figures
in the _key_ line, annexing the 2 to the extreme left; this will
constitute the complete answer.

It, of course, is not necessary to adhere to two pairs of 9’s; there
may be three, four, or even more; but the total number of lines,
including the _key_ line, must be _odd_, and the number of pairs must
be deducted from the unit figure of the _key_ line, and this same
number be written down at the extreme left. The number of figures in
each line should always be the same. As the location of the _key_
line may be changed if necessary, the artifice could not easily be
detected.

=NUMBER 9.=

If two numbers divisible by 9 be added together the sum of the
figures in the amount will be either 9 or a number divisible by 9.

                      Example:   54
                        (1)      36
                                 --
                                 90

If one number divisible by 9 be subtracted from another number
divisible by 9, the remainder will be either a 9 or a number
divisible by 9.

                      Example:   72
                        (2)      18
                                 --
                                 54

If one number divisible by 9 be multiplied by another number
divisible by 9, the product will be divisible by 9.

                       Example:   54
                         (3)      27
                                ----
                                1458

If one number divisible by 9 be divided by another number divisible
by 9, the quotient will be divisible by 9.

                  Example:   27)3645
                    (4)         ----
                                 135

In the above examples it is worth noting that the figures in each
answer added together continually produce 9.

    (1) 90 = 9     (2) 54 = 9     (3) 1458 = 18 = 9     (4) 135 = 9

Also, if these answers be multiplied by any number whatever, a
similar result will be produced.

                 Example: 135 x 8 = 1080 = 9

If any row of two or more figures be reversed and subtracted
from itself, the figures composing the remainder will, when added,
be a multiple of 9, and if added together continually will result in 9.

                 Example:   7362
                            2637
                            ----
                            4725 = 18 = 9

Tell a person to write a row of figures, then to add them together,
and to subtract the total from the row first written, then to cross out
any one of the figures in the answer, and to add the remaining
figures in the answer together, omitting the figure crossed out; if the
total be now told, it is easy to discover the figure crossed out.

                Example:    4367256 = 33
                                 33
                            -------
                            4367223 = 27

It should be observed that the figures of the answer to the
subtraction when added together equal 27--a multiple of 9; this,
of course, is always the case. Now, suppose that 7 was the figure
crossed out, then the sum of the figures in the answer (omitting
7) would be 20; this number being told by the person, it is easily
seen that 7 must have been crossed out, as that figure is required
to complete the multiple 27. If after the figure has been crossed
out, the remaining figures total a multiple of 9, it is evident that
either a cipher or a 9 must have been the figure erased.

Multiply the digits--omitting 8--by any multiple of 9, and the
product will consist of that multiple,

                    Example:   12345679      36 = 4 x 9
                                     36
                               --------
                              444444444

If a figure with a number of ciphers attached to it be divided by
9, the quotient will be composed of that figure only repeated as many
times as there are ciphers in the dividend; with the same figure as
the remainder.

                  Example:   9)7000000
                                --------
                                777777-7

“Dear Teecher,--Please excuse John for staying home--he had the

“A country schoolmaster received from a small boy a slip of paper

Unable to understand, the small boy explained to the master that his
big brother had been “kept at home to go taturing”--that is, to dig
potatoes.


“Tommy,” said the school teacher, “you must get your father to give
you an excuse the next time you stay away from school.”

“That’s no use, teacher. Dad’s no good at making excuses; mother
bowls him out every time.”

9d. less than he otherwise would have done. In what time could B and
C reap the field alone?

RELIGIOUS RECKONING.--(THE NEW JERUSALEM.)

Revelations xxi. (15)--“_And he that talked with me had a golden
rule to measure the city and the gates thereof and the wall thereof_;

(16) “_And the city lieth four square, and the length is as large
as the breadth, and he measured the city with the reed twelve thousand
furlongs. The length and the breadth and the height of it are equal._”

12,000 furlongs = 7,920,000 feet, which cubed = 496793088000000000000
cubic feet; half of this we will reserve for the Throne and Court of
Heaven, and half the balance for streets, &c., leaving a remainder
of 124198272000000000000 cubic feet. Divide this by 4096 (the cubic
feet in a room 16 feet square) and there will be 3032184375 000000
rooms. Suppose that the world always did and always will contain
990,000,000 inhabitants, and that a generation lasts 33⅓ years,
making in all 2,970,000,000 every century, and that the world will
stand 100,000 years, totalling 2,970,000,000,000 inhabitants; then
suppose there were 100 worlds equal to this in number of inhabitants
and duration of years, making a total of 297,000,000,000,000 persons.
There would then be more than 100 rooms 16 feet square for each person.

THE PUZZLE ABOUT THE “PER CENTS.”

There are many persons engaged in business who often become badly
mixed when they attempt to handle the subject of per centages. The
ascending scale is easy enough: 5 added to 20 is a gain of 25%; given
any sum of figures the doubling of it is an addition of 100%. But
the moment the change is a decreasing calculation the inexperienced
mathematician betrays himself, and even the expert is apt to stumble
or go astray. An advance from 20 to 25 is an increase of 25%; but the
reverse of this, that is, a decline from 25 to 20 is a decrease of
only 20%.

There are many persons, otherwise intelligent, who cannot see why the
reduction of 100 to 50 is not a decrease of 100%, if an advance from
50 to 100 is an increase of 100%.

The other day, an article of merchandise which had been purchased
at 10 pence a pound was resold at 30 pence a pound--an advance of
200%. Whereupon, a writer in chronicling the sale said that at the
beginning of the recent depression several invoices of the same class
of goods which had cost over 30 pence per pound had been finally sold
at 10 pence per pound--a loss of over 200%! Of course there cannot
be a decrease or loss of more than 100%, because this wipes out the
whole investment and makes the price nothing. An advance from 10 to
30 is a gain of 200%; but a decline of 30 to 10 is a loss of only
66⅔%.

A very deserving trader was ruined by his miscalculations respecting
mercantile discounts. The article he manufactured he at first
supplied to retail dealers at a large profit of about 30%. He
afterwards confined his trade almost exclusively to large wholesale
houses, to whom he charged the same price, but allowed a discount of
20%, believing that he was still realising 10% for his own profit.
His trade was very extensive, and it was not till after some years
that he discovered the fact that in place of making 10% profit, as
he imagined, by this mode of making his sales he was realising only
4%. To £100 value of goods he added 30%, and invoiced them at £130.
At the end of each month, in the settlement of accounts amounting to
some thousands of pounds with individual houses, he deducted 20%, or
£26 on each £130, leaving £104, value of goods at prime cost, instead
of £110, as he all along expected.

MIND-READING WITH CARDS.

Hand the pack (a full one) to be shuffled by as many spectators
as wish; then propose that someone takes the pack in his hand and
secretly chooses a card, not removing it, but noticing at what number
it stands counting from the bottom; he then returns the pack to you.

Now you have to tell what number the card is from the top. You ask
any one of the spectators to choose any number between 40 and 50, and
whatever number is chosen the card will appear at that number in the
pack. Let us suppose the number chosen is 48.

You then say that it is not necessary for you to even see the cards,
which will give you a good excuse for holding them under the table,
or behind your back. Now subtract the number chosen, 48, from 52,
which gives remainder 4, count off that many cards from the top, and
place them at the bottom. You next say to the gentleman who chooses
the card, that “it is now number 48, according to the general desire,
would you please let us know at what number it originally stood?”
Suppose he answers 7. Then, in order to save time, you commence
counting from the top at that number, dealing off the cards one by
one, calling the first card 7, the next 8, and so on. When you reach
48, it will be the card the gentleman had chosen. It is not necessary
to limit the choice of position to between 40 and 50, but it is
better for two reasons.

First, that the number chosen be higher than that at which the card
first stood, also the higher the number chosen, the fewer cards are
there to slip from the top to the bottom.

PARSING.

“What part of speech is ‘kiss’?” asked the High School teacher.

“A conjunction,” replied one of the smart girls.

“Wrong,” said the teacher, severely. “Next girl.”

“A noun,” put in a demure maiden.

“What kind of a noun?” continued the teacher.

“Well--er--it is both common and proper,” answered the shy girl, and
she was promoted to the head of the class.


“QUICK.”

TEACHER (to class)--“What is velocity?”

BRIGHT YOUTH--“Velocity is what a person puts a hot plate
down with.”

A NEW WAY OF PUTTING IT.

    “Dirty days hath September,
    April, June and November;
    From January up to May,
    The rain it raineth every day.
    All the rest have thirty-one,
    Without a blessed gleam of sun;
    And if any of them had two and thirty,
    They’d be just as wet and twice as dirty.”


Does the top of a carriage wheel move faster than the bottom? This
question seems absurd. That the top moves faster, however, is
perfectly correct; for if not it would simply move round in the same
place: in a wheel on a fixed axle the bottom moves backward as fast
as the top moves forward; but in a wheel that is going forward,
drawn by a progressive axle, the bottom does not go back at all, but
remains almost stationary until it is its turn to rise and go forward.


37. A General, arranging his army in a solid square, finds he has 284
men to spare, but on increasing the sides of the square by one man,
he wants 25 men to complete the square. How many men has he?


“STEWING.”

38. A student reads two lines more of “Virgil” each day than he did
the day before, and finds that, having read a certain quantity in
18 days, he will read at this rate the same quantity in the next 14
days. How much will he read in the whole time?


39. Two bootmakers who lived in the town of B., thrown out of
employment, resolved to go to G., a town 24 miles north from B.,
where there is a large factory; one of them went straight on to G.,
but the other went first to C., a small township west of B., and then
went direct to G., his whole journey being 45 miles. What is the
distance from C. to G.?


40. A tree which grows each year 1 inch less than the previous year,
grew a yard in the first year; the value of the tree at any time is
equal to the number of pence in the cube of the number of yards of
its height. What is the value of the tree when done growing?


THIS OFTEN “STICKS” PEOPLE UP.

41. What two odd numbers multiplied together make 7?


MAGIC SQUARES.

A Magic Square is a series of figures arranged in the equal divisions
of a square in such a manner that the figures in each row when added
up, whether horizontally, vertically, or diagonally, form exactly the
same sum.

They have been called “Magic” because the ancients ascribed to them
great virtues, and because this arrangement of numbers formed the
basis and principle of their talismans. Archimedes devoted a great
amount of attention to them, which has caused a great many to speak
of them as “the squares of Archimedes.” They may be either odd or
even. When the former, the following method will be found valuable:--

With the digits from 1 to 25 form a square so that the numbers when
added up horizontally, vertically, or diagonally will amount to 65.

_Method._--Imagine an exterior line of squares above the magic square
you wish to form, and another on the right hand of it. These two
imaginary lines are shown in the diagram.


         18   25    2    9
  +----+----+----+----+----+
  | 17 | 24 |  1 |  8 | 15 | 17
  +----+----+----+----+----+
  | 23 |  5 |  7 | 14 | 16 | 23
  +----+----+----+----+----+
  |  4 |  6 | 13 | 20 | 22 | 4
  +----+----+----+----+----+
  | 10 | 12 | 19 | 21 |  3 | 10
  +----+----+----+----+----+
  | 11 | 18 | 25 |  2 |  9 |
  +----+----+----+----+----+

1st. In placing the numbers in the square, we must go in the
ascending diagonal direction from left to right, any number which, by
pursuing this direction, would fall into the exterior line must be
carried along that line of squares, whether vertical or horizontal,
to the last square. Thus, 1 having been placed in the centre of the
top row, 2 would fall into the exterior square above the fourth
vertical line; then ascending diagonally 3 falls into the square
diagonally from 2, but 4 falls out of it to the end of a horizontal
line, and it must be carried along that line to the extreme left and
there placed. Resuming our diagonal ascension to the right we place 5
where the reader sees it, and would place 6 in the middle of the top
row, but as we find 1 is already there we look for the direction to

2nd. That when in ascending diagonally we come to a square already
occupied, we must place the number which, according to the 1st rule
should go into that occupied square directly under the last number
placed: thus, in ascending with 4, 5, 6, the 6 must be placed under
the 5, because the square next to 5 in diagonal direction is occupied.


A Promising Sign--I O U.


HOW TO FIND THE TOTAL OF A ROW OF FIGURES IN A MAGIC SQUARE.

_Rule._--Multiply half the sum of the extremes by the square root of
the greatest extreme.

Referring to the example given above, we see that the extremes 1 and
25 added equal 26--half of which is 13; this multiplied by 5 (the
square root of 25) gives 65 as the total for each row.

Again, in the next question, the two extremes 1 and 81 equal 82, half
of this sum is 41, which multiplied by 9 (the square root of 81)
gives 369 as the total for each row.


42. Arrange the figures from 1 to 81 in a square that when added up
horizontally, vertically, or diagonally the sum will be 369.


HOW THEY WORKED IT.

Mick and Pat, working in the country some distance from a hotel,
arranged with the landlord to take to their hut a small keg of rum.
They were unable to pay for the liquor at the time, having only one
threepenny piece between them; but Mick proposed that every time he
had a drink he would give Pat threepence, and Pat also agreed to
pay Mick for his drinks, the cash thus gathered to be brought to
the publican when the keg was empty. This proposal was accepted by
the publican, the keg of rum handed over to the two Irishmen, who
immediately started on their journey. They had not proceeded very far
before their burden made them thirsty. Mick is the first to pull up
with: “Hold on, Pat, I think I’ll have a drink.” “Begorra,” replied
Pat, “you’ll have to pay me for it then.” Mick hands the 3d. to Pat
before having a good “pull.” Pat now being the possessor of the price
of a drink, slakes his thirst by paying Mick 3d. for it. This form
of payment is kept up till the rum has disappeared. On their next
visit to the hotel, the 3d piece is handed to the landlord as being
payment, according to terms of agreement adopted by him.


43. Arrange the figure’s from 1 to 9 in a square, so that they will
add up to 15, horizontally, vertically, or diagonally.

THE DISHONEST SERVANT.

46. A gentleman having bought 28 bottles of wine, and suspecting his
servant of tampering with the contents of the wine cellar, caused
these bottles to be arranged in a bin in such a way as to count 9
bottles on each side. Nothwithstanding this precaution, the servant
in two successive visits stole 8 bottles--4 each time--re-arranging
the bottles each time so that they still counted 9 on a side. How did
he do it?

A “TAKE-DOWN” WITH CARDS.

This is a card trick which depends upon a certain “key,” the
possessor of which will always have the advantage over his
uninstructed adversary. It is played with the first six of each
suit--the four aces in one row, next row the deuces, threes,
fours, fives and sixes. The object now will be to turn down cards
alternately, and endeavour to make thirty-one points by so turning
without over-running that number. The chief point is to count so as
to end with the following numbers: 3, 10, 17 or 24.

For instance, we will suppose it your privilege to commence the
count; you would commence with 3, and your adversary would add 6,
which would make 9; it would be then your policy to add 1 and make
10; then, no matter what number he adds he cannot prevent you making
17, which gives you the command of the trick. We will suppose he adds
6 and make 16; then you add 1 and make 17; then he to add 6 and make
23, you add 1 and make 24; then he cannot add any number to make 31,
as the highest number he can add is 6, which would only count 30, so
that you can easily add the remaining 1 and make 31.

If your adversary is not wary, you may safely turn indifferent
numbers at the beginning, trusting to his ignorance to let you count
17 or 24; but, as his knowledge increases, he will soon learn that 24
is a critical number, and to play for it accordingly.

If both players know the trick, the first to play must be the winner,
as he is sure to begin with a 3, which commands the game.

THE GEOMETRICAL WONDER AND ARITHMETICAL ABSURDITY.

Take a piece of cardboard 13 inches long and 5 wide, thus giving a
surface of 65 inches. Cut this strip diagonally, giving two pieces
in the shape of a triangle, and measure exactly 5 inches from the
larger end of each strip and cut in two pieces. Take these strips and
put them into the shape of an exact square, and it will appear to be
just 8 inches each way, or 64 inches--a loss of one square inch of
superficial measurement with no diminution of surface.

OFTEN ASKED.

51. What is the difference between 4 square miles and 4 miles square?


TO TELL THE NUMBER THOUGHT OF ON A CLOCK.

Ask a person to think of any number on the dial of a clock; you then
point, promiscuously at the various numbers, telling the person to
add the number of times you point to the number he thought of, and
when the total reaches 20, you will be pointing at the number he
selected.

For instance, suppose he selected the number 5. You point
indifferently 7 times at the various numbers, but the 8th time your
pointer must be at XII., his addition will then be 13 (for 5 and 8
added equal 13), the next at XI., his addition then 14, next at X.,
and so on. When he calls 20, you will be pointing at the number he
thought of--5.

[Illustration]


A very amusing experiment is to ask a person to write down the
figures around the dial of a clock. Nearly all know that the figures
are generally the Roman numerals; but, in writing them down, when
they come to the four, it is very often written IV. instead of IIII.

It is said that a certain king, being unable to find any other fault
in a clock that had been constructed for him, declared that the
figure four should be represented by four strokes (IIII) instead
of IV. In vain did the clock-maker point out the mistake, for his
majesty adhered obstinately to his own opinion, and angrily ordered
the alteration to be made. This was done, and the precedent thus
formed has been followed by clockmakers ever since.

PANCAKE DAY.

53. On Shrove Tuesday last, I’ll tell you what pass’d
        In a neighbouring gentleman’s kitchen,
    Where pancakes were making, with eggs, and with bacon
        As good as e’er cut off a flitchen.
    The cook-maid she makes four lusty pancakes
        For William her favourite gardener,
    “Pray be quick with that four,” cries Jack, “and make more,
        For William won’t let me go partner.”
    Being sparing of lard, the pan’s bottom she marr’d
        In making the last of Will’s four;
    So she said, “Pr’ythee, John, run and borrow a pan,
        Or else I can’t make any more.”
    Jack soon got a pan, but found by his span
        That the first was more wide than the latter,
    This being a foot o’er, whereas that before
        Was three inches more and a quarter.
    Jack cries, “Don’t me cozen, but make half a dozen.
        For the pan is much less than before;”
    Says Will, “For a crown (and I’ll put the cash down)
        Your six will be more than my four.”
    “Tis done,” says brisk Jack, and his crown he did stake,
        So both of them sent for a gauger;
    The dimensions he takes, of all their pancakes,
        To determine this important wager.
    He found, by his stick, they were equally thick,
        So one of Will’s cakes he did take,
    Which he straight cut in twain, twelve one-fifth[1] the chord line;
        And gave the less piece unto Jack.
    “To the best of my skill,” says the gauger, “this will
        Make both of your shares equal and true;”
    Will swore that he lied, so, the point to decide,
        They refer themselves, sirs, unto you;
    Then pray give your answers, as soon as you can, sirs,
        For what with their quarrels and jars,
    We’re afraid of some murder, for no day goes over
        But they fight, and are cover’d with scars!

Interesting Items About the Almanac.


The reason why February has only 28 days, while the other months have
30 and 31 is attributable to the vanity of the Emperor Augustus.
His uncle and predecessor corrected the calendar, arranging the
year almost as we have it now; he gave to the year 12 months, or
365¼ days. The months were--March (the first month), April, May,
June, Quintilis, Sextiles, September, October, November, December,
January, and February (the latter being the last month of the year,
which among the Romans had consisted originally of 10 months). Cæsar
ordered that the year should begin with January, and divided the
days among them thus: January, March, May, Quintilis, September,
and November each had 31 days; April, June, Sextiles, October and
December had 30 days each; and February (the last month added to the
year) had 29 days regularly and a 30th day every fourth year. After
Julius Cæsar’s death, Mark Antony changed the name of Quintilis to
July as we have it now. Augustus wanted a month for himself, and
wanted it as long as his uncle’s month, so he took Sextiles for his
and changed the name to August. Then he took February’s 29th day and
added it to August, so that it might have 31 days; and, to avoid
having 3 months of 31 days each in succession, September and November
were reduced to 30 days, and October and December increased to 31
days each.


Previous to the year 1752, the legal year in England commenced on
the 25th March. In that year it was enacted that the legal year
should begin on 1st January. The change brought the calendar into
unison with the actual state of the solar year. It is curious that
in Scotland the change which made the legal year begin on January
1st was effected in 1600. For some time after the change in England,
legal documents contained two dates for the period intervening
between 1st January and 25th March--that of the old year and that of
the new.


During the time of Oliver Cromwell, Christmas Day was described as a
superstitious festival, and put down in England by the strong hand of
the law.


There has been a superstitious notion that Fools’ Day dated back to
the time of Noah’s Ark. The dove that was sent forth from the Ark is
supposed to have returned on April 1st.


THE MOST REMARKABLE MONTH was February, 1866. It had no full
moon. January had two full moons, and so had March, but February had
none. This had not occurred since the creation of the world, and it
will not occur again, so scientists tell us.

_All Fools’ Day_ had it’s origin in France, before the time of the
Reformed Calendar. When the year commenced on March 25th, the French
frequently paid their New Year’s visits and bestowed their gifts on
April 1st, as March 25th occurred in Passion Week. After the adoption
of the new calendar, however, these New Year’s observances took place
on January 1st, and it was a common thing for people to forget the
change of date. Pretended presents and mock ceremonial visits became
common, and the persons thus imposed on were known as April fish,
_i.e._, a mackerel, which, like a fool, is easily caught. Hence,
All Fools’ Day.

ledge, how many seconds elapsed from the ball leaving my hand till it
touched the earth, and what was the acquired velocity at the moment
of contact?


PRACTICAL ILLUSTRATION.

In one of our great public schools a master known to successive
generations of his pupils for fifty years as “old Buggus” delighted
in surprising his boys with strange sayings and doings. On one
occasion, desirous of illustrating a question in the arithmetic
lesson, he said to a boy, “I am a tripe merchant, and this platform
is my shop. You will come here and buy a pound of tripe. Now, begin.”

[Illustration]

“Please, I want a pound of tripe,” said a boy, sauntering up.
“Where’s your money?” demanded old Buggus, hoping to put the boy out
of countenance.

“Where’s your tripe?” was the ready retort; but it gained for its
unfortunate author four hours’ detention on the next holiday.

“MORE HASTE LESS SPEED.”

56. A compositor, hurrying whilst setting up type for an arithmetic
book--“How to Become Quick at Figures”--accidentally dropped the work
of a problem; unfortunately he mislaid the copy, and all that he
remembered was that both multiplicand and multiplier consisted of two
figures. The scattered type represented the following figures:--1, 2,
3, 3, 4, 6, 7, 8, 8, 9, 9. With the aid of a pencil and a piece of
paper the compositor managed after a while to rearrange the figures
in their proper place. What was the problem?

PROFITABLE CARELESSNESS.

A very amusing story is told of a harness-maker who lived some years
ago in London. He had a handsome saddle in his shop, occupying a
conspicuous position therein. On his return from luncheon one day he
observed that the saddle was gone. Calling to his foreman, he said:

“John, who has bought the saddle?”

“I’m sure I don’t know, sir,” said the foreman, scratching his head
as if he were trying to think. “I cannot tell, and the worst part of
it is, it hasn’t been paid for. While I was at work in the back of
the shop a gentleman came in, priced it, decided to take it, told
me to charge it, and throwing it into his trap, drove off, before I
could think to ask his name.”

“That was very stupid of you,” said the harness-maker, disposed to be
angry at the man’s carelessness. “Very likely we have been robbed.”

“I don’t think that sir,” said the foreman, “for I’m very sure that
the gentleman has traded here before.”

“Well, I can’t afford to lose the money,” said the harness-maker.
“We’ll have to find out who took it and send him the bill. Ah!” he
added, with a smile, after a moment’s reflection, “I have it. We’ll
charge it up to the account of every one of our customers who keep
open accounts here. Those who didn’t get it will refuse to pay, so we
shall be all right.”

“The book-keeper was instructed to do this, and the bills in due
course of time went out. Some weeks later the harness-maker asked the
book-keeper if he had succeeded in discovering who the customer was.

“No, sir,” he replied, “and we never shall, I fear, sir, for about 40
people have paid for it already without saying a word.”


A CYCLE CATCH.

Tie a cord to the pedal of a bicycle, such pedal to be the one that
is the nearer to the ground, and, standing behind the back wheel,
pull the cord, when, strange as it appears, the machine will come
towards you, although everyone would first imagine that the bicycle
would move forward. How is this?

TO TELL THE SPOTS ON THE BOTTOM CARDS OF SIX HEAPS.

Allow anyone to choose six cards from a full pack. Tell him the
court cards count 10, and the other cards according to their pips.
Having made his selection, tell him to lay the chosen cards upon the
table face downwards, without allowing you to see them, and to place
upon each as many cards as pips are required to make 12. Whilst he
is doing so, you should be out of the room or blindfolded. On your
return he hands you the cards left over, and you have to tell the
total number of spots on the six bottom cards.

Suppose he had chosen 10, 6, 1, K, 3 and 7, which totals 37, now
on the 10, he would place two cards to make 12; on the 6, he would
place 6; and on the 1, 11 would be placed, and so on. On receiving
the remaining cards from him you pretend to be looking through them
carefully, but you simply want to know how many he has given you,
which in the above example would be 11. To this number you add 26,
which gives 37, the total spots required.

Should there not be enough cards left on hand to complete the six
heaps, you can ask him how many cards he is short of, and this
number, subtracted from 25, will give the total. It is better not to
allow the person to choose six cards right off at the beginning, but
for him to shuffle and cut the pack as he pleases, and to take the
cards as they come.


BOOK-KEEPING COMMANDMENTS.

By _Ledger_ laws, what I receive Is _Debtor_ made to those who

_Profit and Loss_ accounts are plain, I Debit loss and Credit gain.


57. How far does a man walk while planting a field of corn 285 feet
square, the rows being 3 ft apart from the fence?


A MATTER OF OPINION.

A man walks round a pole on the top of which is a monkey. As the man
moves, the monkey turns on the top of the pole, so as still to keep
face to face with the man. Now, when the man has gone round the pole,
has he or has he not gone round the monkey?

TRY IT.

Take the number 15, multiply it by itself, and you have 225; now
multiply 225 by itself, then multiply that product by itself, and
so on until 15 products have been multiplied by themselves in turn.
The final product called for contains 38,539 figures (the first of
which is 1412). Allowing three figures to an inch, the answer would
be over 1070 feet long. To perform the operation would require about
50,000,000 figures. If they can be made at the rate of 100 a minute,
a person working 10 hours a day for 300 days in each year would be 28
years on the job.


PATHETIC ADVERTISING.

“Died, on the 11th ultimo., at his shop in Fleet-street, Mr. Edward
Jones much regretted by all who knew and dealt with him. As a man,
he was amiable; as a hatter, upright and moderate. His virtues were
beyond all price, and his beaver hats were only £1 4s each. He has
left a widow to deplore his loss, and a large stock to be sold cheap
for the benefit of his family. He was snatched to the other world in
the prime of life, and just as he had concluded an extensive purchase
of felt, which he got so cheap that the widow can supply hats at
a more moderate charge than any house in London. His disconsolate
family will carry on his business with punctuality.”


58. In one corner of a hexagonal grass paddock each of the sides of
which is 40 yards long, a horse is tethered with a rope 50 yards
long. How many square yards can he graze over?


59. A and B start together from the same point on a circular path,
and walk till they both arrive together at the starting point. If A
performs the circuit in 224 seconds and B in 364 seconds, how many
times do they each walk round?


“IF.”

If you could sell the sea at 1d. per 10,000 gallons, it would bring
in 155 billion pounds. If you were to try and pump it dry, at the
rate of 1,000 gallons per second, it would take 12,000 million years.
There is always an “if” in these things!

BAD WRITING.

In a well-known firm in Sydney the clerks are presided over by a
rather impetuous manager, whose violent fits of temper very often
dominate his reason. For instance, the other day he was wiring into
one of them about his bad work.

“Look here, Jones,” he thundered, “this won’t do. These figures are a
perfect disgrace to a clerk! I could get an office boy to make better
figures than those, and I tell you I won’t have it! Now, look at that
five, it looks just like a three. What do you mean, sir, by making
such beastly figures? Explain!”

“I--er beg your pardon, sir,” suggested the trembling clerk, his
heart fluttering terribly, “but--er well, you see, sir, it is three.”

“A three?” roared the manager; “why, it looks just like a five!”


63. Write 24 with three equal figures, neither of them being 8.


THE WRONG COLUMN.

64. A clerk, while posting from day book to ledger, transposed an
amount by placing the pence in the shilling column and the shillings
in the pence column, thereby causing an error of 9s. 2d. With what
amount could he make such a mistake?


EDUCATIONAL VAGARIES.

_Extracts from Reports of Country Provisional Schools._

School No. 1: On roll, 1 boy, 1 girl; total, 2. Average attendance,
0·6 boy, 0·6 girl; total, 1·2.

School No. 2: On roll, 2 boys, 2 girls; total 4. Average attendance,
1·6 boys, 1·3 girls; total, 2·9.

School No. 3: On roll, 2 boys, no girls. Average attendance, 0·8 boys.

By the above we see the public are paying for a teacher to provide
education for eight-tenths of a boy!

A DISPUTE.

66. Two men have an equal interest in a grindstone, which is 5 ft.
6 in. in diameter. The centre of the stone, to the extent of a
diameter of 18 in., is useless, and not to be taken into account.

Required to find the depth to which the first partner may be allowed
to grind away from the stone in order to leave an equal share of the
stone to the second partner.

BANK NOTE VERSE.

On the backs of bank notes one sometimes meets with strange
and peculiar sentiments. “Go, poor devil, get thee gone,” is the
kind of parting salutation most in favour; but the following is chiefly
notable as a rare instance of the bank-note rhymester parting with
his money in a Christian spirit:

    Farewell, my note, and wheresoe’er ye wend,
    Shun gaudy scenes, and be the poor man’s friend;
    You’ve left a poor one--go to one as poor;
    And drive despair and hunger from his door.


An Irish merchant, who felt annoyed at a complaining letter he
received from a customer, wrote back:--“We decline to acknowledge the
receipt of yours of the 15th.”


If to-day is the to-morrow of yesterday, is to-day the yesterday of
to-morrow?

67. Suppose that four poor men build their houses around a pond, and
that afterwards four evil-disposed rich men build houses at the back
of the poor people--as shown in illustration--and wish to have a
monopoly of the water: how can they erect a fence so as to shut the
poor people off from the pond?

SOME TRADE SIGNS AND MOTTOES.

Many curious inscriptions are to be found displayed on shop windows,
office doors, etc.

Here are a few:--

A Pawnbroker.--“Mine is a business of the greatest interest.”

A Flourishing Bootmaker.--“Don’t you wish you were in my shoes?”

A Publican.--“Good beer sold here, but don’t take my word for it.”

A Hairdresser.--“Two heads are better than one.”

A Carter.--“Excelsior--hire and hire.”

A Baker.--“The staff of life I do supply, by it you live and so must I.”

A Butcher.--“We kill to dress, not dress to kill.”

A Builder.--“I send innocent men to the ‘scaffold.’”

A Clerk.--“I possess more pens than pounds.”

A Dentist.--“I look ‘down in the mouth’ and am happy.”

A Doctor.--“I take pains to remove pains.”

A Hatter.--“I shelter ‘the heir apparent’ and protect ‘the crown.’“

A Photographer.--“Mine is a developing business and mounting rapidly.”

A Solicitor.--“I study the law--and the profits.”

An Undertaker.--“No complaints from our customers.”


RIVAL BUTCHERS.

T. JONES.--“Sausages, 3d. per lb.--to pay more is to be
robbed.”

J. SMITH.--“Sausages, 4d. per lb.--to pay less is to be
poisoned.”


A French confectioner, proud of his English, and wishing to let his
customers know that their wants would be attended to without delay,
put out the notice, “Short weights here.”

A shopkeeper in the old country had printed under his name “The
little rascal.” When asked the meaning of this strange sign, he
replied, “It distinguishes me from the rest of my trade, who are all
great rascals.”


On an Office Door.--“Shut this door, and as soon as you have done
talking on business, serve your mouth the same way.”


“SHE.”

68.
        A country spark addressed a charming “she,”
        In whom all lovely features did agree;
        But being void of numbers, as doth show,
        Desirous was the lady’s age to know.
        “My age is such that if multiplied by three,
        Two-sevenths of the product triple be:
        The square root of two-ninths of that is four;--
        Tell me my age or never see me more.”

RUNNING SHORT.

69. A vessel on a 3 months’ trip has provisions for 4 months, but
the stores are served out as if the voyage had to be completed in 3
months. At the end of 2 months, it is discovered that the voyage will
take 3½ months. To what proportion must the rations be reduced for
the remaining time?


In a certain town in the North of Queensland, a class of young
men was formed to receive lessons in short methods of business
arithmetic. The teacher was endeavouring to knock into the head of
a young man that the cost of a dozen articles is the same number of
shillings that a single article costs in pence. To illustrate the
rule, he gave the following example:--

“If I buy 1 dozen apples at 1d each, then the dozen will cost 1
shilling; and if I buy 1 dozen oranges at 2 pence each, the dozen
will cost 2 shillings. Now, supposing I buy 1 dozen at 3 pence each,
how much will the dozen cost?”

YOUNG MAN (after two minutes’ reflection)--“Are they apples
or oranges?”


A DRAUGHTS PUZZLE.

70. Ten draughtsmen are placed in a row. The puzzle is to lift one up
and passing over two at a time (neither more nor less) to place it on
the top, or to “crown” the next one, continuing in this fashion until
all are crowned. In passing over a piece already crowned, it is to be
reckoned as two pieces.


71. In the centre of a pond 20 feet square there is a small island,
on which is growing a tree. Two boys notice there is a bird’s nest
on the top of the tree, but the difficulty is to reach the island,
as they have 2 short planks that only measure 8 feet each. After a
little while they hit on an ingenious plan, and, without nailing the
planks together, manage to place them so they can reach the tree in
safety. How did they do it?


TEACHER--“Now, I want all the children to look at Tommy’s
hands, and see how clean they are, and see if all of you cannot come
to school with cleaner hands. Tommy, perhaps, will tell us how he
keeps them so nice?”

TOMMY--“Yes ’m; mother makes me wash the breakfast things
every morning.”


BRAIN-BEWILDERERS.

An amusing periodical got up by the boys of a certain college gives a
capital skit on the style of examination-papers frequently presented
for the torture of pupils. Here are a few examples:--

Supposing the River Murray to be three cubits in breadth--which
it isn’t--what is the average height of the Alps, stocks being at
nineteen and a-half?

If in autumn apples cost fourpence per pound in Melbourne, and
potatoes a shilling a score in spring, when will greengages be sold
in Brisbane at three-halfpence each, Sydney oranges being at a
discount of five per cent.?

If two men can kill twelve kangaroos in going up the right side of a
rectangular turnip-field, how many would be killed by five men and a
terrier pup in going down the other side?

If a milkmaid four feet ten inches in height, while sitting on a
three-legged stool, took four pints of milk out of every fifteen
cows, what was the size of the field in which the animals grazed, and
what was the girl’s name, age, and the occupation of her grandfather?

If thirty thousand millions of human beings have lived since the
beginning of the world, how many may we safely say will die before
the end of it? N.B.--This example to be worked out by simple
subtraction, algebra, and the rule of three. Compare results.


72. Find two numbers in the proportion of 9 to 7 such as the square
of their sum shall be equal to the cube of their difference.




ARITHMETICAL THOUGHT READING.


A great deal of fun can be derived from puzzles of this nature--they
are endless in variety--and as they depend upon some principle in
arithmetic should be easily remembered.

Example 1.
            Think of a number, say                         5
            Double it                                     10
            Add 5                                         15
            Add 12                                        27
            Take away 3                                   24
            Halve it                                      12
            Take away number first thought of--5
            The answer will _always_ be                    7


Example 2.
            Think of a number, say                         8
            Square it                                     64
            Subtract the square of the number which is
              1 less than the number thought of--that
              is 7--whose square is 49--leaves            15
            Add 1                                         16

When this last number is told, halve it, and you will arrive at
the original number--8.


Example 3.
            Think of a number, say                         9
            Multiply by 3                                 27
            Add 2                                         29
            Multiply by 3                                 87
            Add 2 more than the number thought of (11)    98

The number of _tens_ in the last answer gives the number thought
of, viz., 9.


Example 4.
            Think of a number, say                         7
            Multiply by 3                                 21
            [If product be odd] add 1                     22
            Halve it                                      11
            Multiply by 3                                 33
            [If product be odd] add 1                     34
            Halve it                                      17

Ask how many 9’s are in the remainder, when, of course, the reply
will be 1.

The secret is to bear in mind whether the first sum be odd or even.
If odd first time, retain 1 in the memory; if odd a second time, 2
more, making 3; to which add 4 for every 9 contained in the remainder.

In the above example, there being only one 9 in 17, this gives us 4,
which added to 3 produces the number thought of--7. When even simply
add 4 for every 9 in remainder.


HOW TO TELL THE AGE OF A PERSON.

Tell a person to write down the figure which represents the day of
the week on which he was born;--thus, 1 for Sunday, 2 for Monday, and
so on; next, the figure for the month--1 for January, 2 for February,
&c.; then the date of the month; now tell him to multiply the number
thus formed by 2, add 5, multiply by 50, and then to add his age, and
from this sum to subtract 365; now you ask him for the remainder, to
which you _secretly_ add 115.

The result will be:--The first figure, the day of the week; the next,
the month in the year; the next, the date of the month; and the last,
the age in years.

Example:

A person was born on Wednesday, 11th June, 1863.

    Write 4, as Wednesday is 4th day of the week.
      "   6, as June is 6th month of year.
      "  11, as that is the date given, 11th June.

  The figures then are--      4611
                                 2
                              ----
                              9222
                                 5
                              ----
                              9227
                                50
                            ------
                            461350
                                35  Age
                            ------
                            461385
                               365
                            ------
                            461020
                               115
                          --------
                         4-6-11-35


A GOOD FIGURE TRICK.

Tell a person to set down a sum of money less than £12, in which
the pounds exceed the pence; next to reverse this amount, making
pence pounds, etc., and to subtract the one from the other, then
set beneath the result itself reversed, adding the last two lines
together, when you will tell him the result, which will _always_
be £12 18s. 11d.

  Example:  £10  8  7
              7  8 10
             --------
              2 19  9
              9 19  2
             --------
            £12 18 11

If the performer be blindfolded the trick looks very mystifying;
he should not, however, repeat it, for many would soon discover
the secret, but as the peculiarity is not confined to money, other
illustrations can be given if required--for instance--if a number of
yds., ft. and inches (less than 12 yds.) be operated on, the final
answer will always be 12 yds. 1 ft. 11 inches; and if a number of
cwts., qrs. and lbs. (less than 28 cwts.) be chosen, the answer will
always be 28 cwts. 2 qrs. 27 lbs.


“Girls” and “Boys.”

At a school examination, the inspector set the girls to write an
essay on “Boys” and the boys to write one on “Girls.”

The following was handed in by a girl of 12:--

“The boy is not an animal, yet they can be heard to a considerable
distance. When a boy hollers he opens his big mouth like frogs, but
girls hold their tongues till they are spoken to, and then they
answer respectable, and tell just how it was. A boy thinks himself
clever because he can wade where it is deep, but God made the dry
land for every living thing, and rested on the seventh day. When the
boy grows up he is called a husband, and then he stops wading and
stays out at nights, but the grew up girl is a widow and keeps house.”

One of the boys sent in:--

“Girls are very stuck up and dignified in their manners and
behaveyour. They make fun of boys, and then turn round and love them.
Girls are the only people that have their own way every time. Girls
is of several thousand kinds, and sometimes one girl can be like
several 1000 girls if she wants anything. I don’t beleive they ever
killed a cat or anything. They look out every nite and say, “Oh,
ain’t the moon lovely!” Thir is one thing I have not told, and that
is they always now their lessons bettern boys. This is all I now
about girls, and father says the less I now the better for me.”

A PROBLEM FOR PLUMBERS.

74. A requires a tank in size capable of holding the quantity of
water that would be caught from the roof of his house in a fall of
3 inches of rain. The roof (commonly called a “hip-roof”) is at an
angle of 45 degrees to the wall plates. The length of house is 30 ft.,
breadth 24 ft., and length of ridge to roof 6 ft. But the eaves of
the iron used for the roofing were so large as to increase its (the
roof’s) dimensions by 3 inches all round, and the spouting added
another 3 inches all round. Find the number of gallons the tank would
require to contain; also dimensions of tank to be made so that its
height must exceed its diameter by no more than 12 inches?

75. Divide 100 into two parts, so that a quarter of one exceeds
one-third of the other by 11.


STRANGE BUT TRUE.

76. Two persons were born at the same place at the same moment of
time; after an age of 50 years they both died also at the same place
and at the same instant, yet one had lived 100 days more than the
other. How was this remarkable event achieved?


ASTRONOMICAL.

77. The planet Jupiter is five times further from the sun than our
earth, and 1331 times larger. Assuming that the diameter of the earth
is 7912 miles, find Jupiter’s diameter, circumference and area.


AN UNSOLVED PROBLEM.

One of the commercial questions of the day which remains to this time
unsettled, is whether the fact of a gentleman having NO TIN may not
have something to do with the answer he invariably sends of NOT IN
when anyone calls on him with a bill.


78. Find nine numbers in arithmetical progression--common difference
3--whose sum is equal to 5670, and arrange in a square, each side
containing three different numbers, so that, when added vertically,
horizontally or diagonally, the sum of each three numbers will amount
to 1890.


79. I have a box. The pieces forming the sides are 5 ft long, and
those forming the ends are 4 ft. broad. The box, when measured
externally all round, measures 18 ft 4 in., and when measured all round
internally, measures 17 ft 8 in. How can this be?

ON BOTH SIDES OF A DOOR IN A MELBOURNE OFFICE.

THE MAN WHO FORGETS THE DOOR.

    Oh, there’s an individual who ev’rywhere abounds,
    Thro’ trains and shops and offices he makes his busy rounds,
    And in and out for ever he is going o’er and o’er,
    To keep somebody after him attending to the door!

    In sultry summer, when to catch a cooling breeze we’ve tried,
    And carefully have opened every door and window wide,
    ’Tis then you may be certain as he vanishes from sight,
    He’ll die but that he’ll shut the door--and close it very tight!

    But when the winds of winter come, with cold and biting breath,
    Oh, then it is the awful wretch is tickled ’most to death!
    His sense of pleasure reaches to a point that is sublime;
    He never fails to leave the door wide open every time!

“SHE” AGAIN.

84.
        The country spark that asked the charming “she”
        How many years of age that she might be,
        Again asked her to tell to him in haste
        How many inches she was round the waist.
        “My waist is such if multiplied by four,
        Four-fifths of product add on my age more,
        The square root of three-fifths of this is six:
        Now find my waist, and get out of this fix.”


SOME LONG WORDS.

The eight longest words in the language are philoprogenitiveness,
incomprehensibleness, disproportionableness, transubstantiationalist,
suticonstitutionalist, honourifibilitudinity, velocipedestrianistical,
and proautionsubstantionist. The last four are not found in the best
dictionaries, but that most hideous word,
“Dacryocystosyringokatakleisis,” is in some of the new lexicons.


HIS OWN GRANDFATHER.

The complication of relationship brought about by marriage is the
cause of many a family squabble, but it is seldom one hears of fatal
results attending such matters. According to an American newspaper,
a resident of Pennsylvania committed suicide a few days ago from a
melancholy conviction that he was his own grandfather.

The following is a copy of a singular letter he left:--“I married a
widow who had a grown-up daughter. My father visited our house very
often, fell in love with my step-daughter, and married her. So my
father became my son-in-law and my step-daughter my mother, because
she was my father’s wife. Some time afterwards my wife had a son; he
was my father’s brother-in-law and my uncle, for he was the brother
of my step-mother. My father’s wife--_i.e._, my step-daughter--had
also a son; he was, of course, my brother, and in the meantime
my grandchild, for he was the son of my daughter. My wife was my
grandmother, because she was my mother’s mother. I was my wife’s
husband and grandchild at the same time. And as the husband of a
person’s grandmother is his grandfather, I was my own grandfather.”
Thus he died, a martyr to his own existence.

85. If 100 stones are placed on the ground, in a straight line, at
the distance of 1 yard from each other, how far will a person travel

A little boy, writing a composition on the zebra, was requested to
describe the animal and to mention what it was useful for. After deep
reflection, he wrote:--“The zebra is like a horse, only striped. It
is chiefly useful to illustrate the letter Z.”


86. I bought a horse and sold him again at 5 per cent. on my
purchase; now, if I had given 5 per cent. less for the horse, and
sold him for 1s. less, I would have gained 10 per cent. What was the
original cost?


87. Find three numbers such that the first with half of the other
two, the second with one-third of the other two, and the third with
one-fourth of the other two, shall be equal to 34?


THE FAMOUS “45” PUZZLE.

88. Take 45 from 45, and leave 45 as a remainder. There are at least
two ways of doing this.

89. How can 45 be divided into 4 such parts that if you add 2 to the
first part, subtract 2 from the second part, multiply the third part
by 2, and divide the fourth part by 2, the sum of the addition, the
remainder of the subtraction, the product of the multiplication, and
the quotient of the division are equal?

90. The square of 45 is 2025, if we halve this we get 20/25 and
20 plus 25 equals 45. Find two other numbers of four figures that
produce the same peculiarity.


91. A mother of a family being asked how many children she had,
replied: “The joint ages of my husband and myself are at present six
times the united ages of our children; two years ago their united
ages were ten times less than ours, and in six years hence our joint
ages will be three times theirs.” How many children had she?


WHERE THE CREEDS AGREE.

The Mahometans, Christians and Jews, with different creeds, are all
striving to reach the same place--Heaven. Now, we will endeavour to
show, by figures, that it is possible for them all to accomplish
their purpose.

The figures 4, 5, 6, at the angles of the large triangle, represent
respectively the above mentioned sects. They are very distant from
each other, but we will induce them to meet half-way. Thus, the
Mahometans and Jews meet at 10, the Mahometans and Christians at 9,
and the Jews and Christians at 11; and by joining these totals to
the opposite numbers we see they all meet at last in Heaven (15).
It should be mentioned that any numbers whatever may be used to
represent the sects, but the result will always be the same.

[Illustration]


“SHE” ONCE MORE.

92. The country spark again addressed the charming “she.” This time
he wished to know her height. She replied, “My height (in inches) if
divided by the product of its digits, gives as quotient 2, and the
digits are inverted by adding 27.”

“You have a bright look, my boy,” said the visitor at the school.
“Yes, sir,” replied the candid youth; “that’s because I forgot to
rinse the soap off my face this morning.”


HIS LAST WILL AND TESTAMENT.

93. A father on his death-bed gave orders in his will that if his
wife, who was then pregnant, brought forth a son, he should inherit
two-thirds of his property, and the mother the remainder; but if she
brought forth a daughter the latter should have only one-third, and
the mother two-thirds. The widow, however, was delivered of twins,--a
boy and a girl. What share ought each to have of the property left
by the father, who had his life insured in the Australian Mutual
Provident Society for £7,000.

A KEEN EYE TO BUSINESS.

Upon the death of the senior partner of an Australian firm a notice
of the sad event was sent to, amongst others, a German lithographic
establishment. The clerk in this German house, who was instructed to
answer the communication, wrote the following letter of condolence:--

“We are greatly pained to hear of the loss sustained by your firm,
and extend to you our heartiest sympathy. We notice the circular you
sent us announcing Mr. S----’s death is lithographed by Messrs.----.
We regret that you did not see your way to let us estimate for the
printing of the same. The next time there is a bereavement in your
house we will be glad to quote you for the lithographic circulars,
and are confident that we can give you better work at less cost
than anybody else in the business. Trusting that we may soon have
an opportunity of quoting you our prices, we remain, with profound
sympathy, yours truly,----.”


An American journal, describing a new counterfeit bank-note, says the
vignette is “cattle and hogs, with a church far in the distance”--a
good illustration of the world.

95. On a square piece of paper mark 12 circles as shown in diagram.
The puzzle is to divide the figure into four pieces of equal size,
each piece to be of the same shape, and to contain three circles,
without getting into any of them.

THE ORIGIN OF THE “STONE.”

Measurement of weight by the “stone” arose from the old custom
farmers had of weighing wool with a stone. Every farmer kept a large
stone at his farm for this purpose. When a dealer came along he
balanced a plank on top of a wall, and put the stone on one end of it
and the bags of wool on the other, until the weights were equal. At
first the stones were of all sorts and sizes and weights, with the
result that dealers who wished to make a living had to be remarkably
knowing in their estimates of them. The many inconveniences involved
by this inequality resulted in all stones being made of a uniform
weight as far as wool was concerned. The weight of a stone of
potatoes, meat, glass, cheese, &c., all differ.


A little boy was reading in his Scottish history an account of the
battle of Bannockburn. He read as follows: “And when the English army
saw the new army on the hill behind, their spirits became damped.”

The teacher asked him what was meant by “damping their spirits,” and
the boy, not comprehending the meaning, simply answered, “Putting
water in their whisky.”


THUNDER AND LIGHTNING CALCULATION.

96. Between the earth and a thundercloud there are four currents of
air, having a temperature of 87, 57, 47, and 37 degrees respectively.
The first current is half the depth of the second, the second half
the third, and the third half the fourth. If a peal of thunder is
heard 2-3251/4256 seconds after the lightning flash, find the depth
of the fourth current and the time occupied by the sound in passing
through it.

   That each portion is fitted in tight,
  Or they will not produce such a neat little square
   As they otherwise would if done right.

QUITE PROPER.

“What is a propaganda,” inquired the teacher. The boy looked at the

or two, and then answered that it was the brother of a proper goose.


DECEMBER AND MAY.

98. An old man married a young woman; their united ages amounted
to 100; the man’s age, multiplied by 4 and divided by 9 gives the

99. A and B set out on a walking expedition at the same time--A from
Melbourne to Geelong, and B from Geelong to Melbourne. On reaching
Geelong A immediately starts again for Melbourne. Now, A arrives at
Geelong four hours after meeting B, but he reaches Melbourne three
hours after their second meeting. In what time did each perform the
journey?


100. What two numbers are those of which the square of the first plus

the subjunctive mood, and ruins you in the future.”


101. “How much money have I,” says a father to his son. Son
replied, “They don’t teach prophecy at our school.” “Well, they
teach arithmetic, I suppose,” rejoined the father, smartly; “if you
multiply one-half, one-third, one-fourth, one-sixth, three-quarters,
and two-thirds of my money together, the product will be 10368. Now
find out how many pence I have.”


102. A person has 1260 quarters of wheat. He sells one-fifth at a
gain of 5 per cent., one-third at a gain of 8 per cent., and the
remainder at a gain of 12 per cent. Had he sold the whole at a gain
of 10 per cent. he would have made £23 2s. more than he did. Find the

line at the rate of 60 miles an hour. A man standing at the extreme
rear of the truck casts a small stone into the air in a perpendicular
direction. The stone travels upward at an average rate of 30 feet per
second for 3 seconds; the height of the man’s hand from ground when
the stone leaves is 15 feet. At what distance behind the train will
the stone strike the ground in its descent?


A Tombstone in an English Cemetery.

Many quaint and puzzling epitaphs are often to be seen engraved
on several of the tombstones in some of the old cemeteries at
Home. The adjoining illustration represents a tombstone in the old

“TAKE CARE OF THE PENCE, &c.”

One of the most startling calculations is the following:--

A penny at 5 per cent. compound interest from A.D. 1 to 1890
would amount to £10,000,000,000,000,000,000,000,000,000,000,000,000,
_i.e._, Ten Sextillions of pounds, or more money than could be
contained in One Thousand Millions of Globes each equal to the Earth
in magnitude, and all of solid gold.


111. On a flagstaff consisting of an upright pole (6 feet of which is
underground) is a cross-yard 24 feet long; the latter is fixed at a
distance of one-third of the length of the visible part of the pole
from the top; passing from the top of the pole to the ends of the
yard are ropes, forming stays whose falls or ends reach to the ground
on either side of the pole, and it is found that these falls just
reach the base of the pole. The total length of rope in the aforesaid
stays is 40 feet. Supposing that the top diameter of the pole is
one-third of that at the extreme base, and that the whole length of
rope used is 54,177 times the base diameter of the pole, what would
the pole cost at 1 penny per 100 cubic inches?

“KEEP YOUR HAIR ON.”

113. Supposing there are more persons in the world than anyone
has hairs on his head, there must be at least two persons who have
the same number of hairs on the head to a hair. Explain this.


114. Show what is wrong in the following:--

8-8 = 2-2, dividing both these equals by 2-2 the result
must be equal; 8-8 divided by 2-2 = 4, and 2-2 divided by
2-2 = 1, therefore, since the quotients of equals divided by
equals must be equal, 4 must be equal to 1.


“GLAD TIDINGS.”

Many will be surprised to hear that there is Scriptural authority
for advertising. Advertising not only has Scriptural authority,
but it is of very respectable antiquity as well. If you will look
in Numbers XXIV., 14, you will find Balaam saying “Come now, and I
will advertise,” and Boaz says in Ruth IV., 4, “And I thought to
advertise.”




OPTICAL ILLUSIONS.


Illusions of the Eye are numberless, and afford a wide field for
experiment. Some people are left-eyed, others right-eyed, and very
few use both eyes equally. It is impossible to tell how far they
really do deceive us unless they have been tested in the proper
manner. For instance, if you ask anyone to what height a bell-topper
would reach if placed on the floor against the wall, nine times out
of ten the height guessed will be half as much again as the real
height of the hat. Everyone seems to _over_-estimate the proper
height.

[Illustration]


Another favourite illusion is to ask a person to mark on the wall a
height from the floor which would represent the length of a horse’s
head: here the majority guess far too little--for a horse’s head is
much longer than most people imagine, ranging from 25 to 34 inches.
In a recent experiment 5 persons out of 6 _under_-estimated the
proper height.

[Illustration]


Here are two triangles. Which is the one whose centre is the better
indicated? (It looks like A, but it is B).

[Illustration]

Again: Out of the two straight lines C and D which is the longer? (By
measurement we see they are both the same).

[Illustration]

Guess, by eye-measurement only, the longest and shortest of the three
lines marked A A, B B, and C C. When you have done guessing measure,
and see how much you are out.

[Illustration]

Which is the tallest gentleman of the three appearing in adjoining
figure?--Many would imagine the last to be the tallest, and the
first the shortest, whereas the reverse is the case--the last is the
shortest, and the first the tallest.

[Illustration]

It is surprising how the eye can be deceived, when dealing with areas
or circles. Place on the table a half-crown and a threepenny-piece;
let these be, say, 9 or 10 inches apart, and ask a friend how many
of the latter can be placed on the former--with this proviso: the
threepenny-pieces must not rest on each other, nor must they overlap
the outer rim of the half-crown; they must be fairly within the
circumference of the larger coin. Many will answer 6, 5, or 4, others
who are more cautious 3. Try for yourself and see how many you can
put on, and you are sure to be surprised.


ARE THESE LINES PARALLEL?

The “herring-bone” figure here illustrated is yet another proof that
our eyes are faulty. The horizontal lines appear to slant in the
direction in which the short intersecting lines are falling, and
would give one the idea that they would meet if continued, whereas
really they are parallel. The illusion is more striking if you tilt
the leaf up.

HOW DID HE DO IT.

115. Once there was an old tramp who had to go through a tollbar,

PAYING A DEBT.

In an office the boy owed one of the clerks threepence, the clerk
owed the cashier twopence, and the cashier owed the boy twopence. One
day the boy, having a penny, decided to diminish his debt, and gave
the penny to the clerk, who in turn paid half his debt by giving it
to the cashier, the latter gave it back to the boy, saying, “That
makes one penny I owe you now;” the office boy again passed it to the
clerk, who passed it to the cashier, who in turn passed it back to
the boy, and the boy discharged his entire debt by handing it over to
the clerk, thereby squaring all accounts.


A TESTIMONIAL.

“How do you like your new typewriter?” inquired the agent.

umpire. He found that A’s money and half of B’s added to one-third of
C’s just came to £32, again that one-third of A’s with one-fourth of
B’s and one-fifth of C’s made up £15, again he found that one-fourth
of A’s together with one-fifth of B’s and one-sixth of C’s totalled
£12. How much had each?

   WANTED Canvasser, energetic; only “live”
            men need apply.  Smart & Co.

A determined-looking young man rushed into Mr. Sharp’s office
the other day, and, addressing him, said abruptly, “See you’re
advertising for a canvasser, sir; I’ve come to fill the place.”

“Gently, young man!--gently! How do you know that you’ll suit?” asked
Mr. Sharp, somewhat nettled at the young man’s off-hand manner.

“Certain of it. Best man you could have--energetic, punctual, honest,
sober, A1 references, and----”

“Wait a minute, I tell you!” shouted Mr. Sharp. “I don’t think you’d
suit me at all.”

“Oh, yes, I shall,” said the young man, seating himself. “And I don’t
go out of this office till you engage me.”

“You won’t?” yelled Mr. S.

“Certainly not,” said the young man, calmly.

“Why, you impudent young scoundrel! I’ll--I’ll kick you out!”

“No, you wont. You may kick me, but you won’t kick me _out_.”

“If you don’t go, I’ll call a policeman,” declared Mr. S., purple
with rage.

“Will you?”

The young man rushed to the door, locked it, and put the key in his
pocket.

Mr. S. gasped and glared, and then roared:--

“I tell you I won’t have you! Get out of my office. Will you take
‘no’ for an answer?”

“No, I won’t take ‘no’ for an answer. Never did in my life, and don’t
intend starting now,” said the young man, very determinedly.

Mr. Sharp hesitated, then rose to his feet, with admiration beaming
from his eyes.

“Young man,” he said, “I’ve been looking for an agent like you for
twenty years. At first I thought you were only a bumptious fool;
but now I see you’re literally bursting with business. If any man
can sell my patent vermin-trap (warranted to catch anything from a
flea to a tiger) you’re that man. A hundred a year and 15 per cent.
commission. Is it a bargain?”

“It is,” said the young man, trying the trap, and smiling approvingly
when it nipped a piece of flesh clean out of his finger.


WHY IS IT?

Take a long narrow strip of paper, and draw a line with pen or pencil
along the whole length of its centre. Turn one of the ends round so
as to give it a twist, and then gum the ends together. Now take a
pair of scissors and cut the circle of paper round along the line,
and you will have two circles. This is a puzzle within a puzzle,
and has never been satisfactorily explained either by scientist or
mathematician.


How to Read a Person’s Character.

Tell a friend to put down in figures the year in which he was born;
to this add 4, then his age at last birthday provided it has not come
in the present year (if it has, then his age last year); multiply
this sum by 1000, and subtract 687,423. (This number is for 1899;
it increases 1000 for each succeeding year.) To the remainder place
corresponding letters of the alphabet. The result will be the popular
name by which your friend is known.

Example: A person was born in 1860, and is now 38 years of age.

An old tradesman used to keep his accounts in a singular manner. He
hung up two boots--one on each side of the chimney; into one of these
he put all the money he received, and into the other all the receipts
and vouchers for the money he paid. At the end of the year, or
whenever he wanted to make up his accounts, he emptied the boots, and
by counting their several and respective contents he was enabled to
make a balance, perhaps with as much regularity and as little trouble
as any book-keeper in the country.


QUICKER THAN THOUGHT.

A little boy, hearing someone remark that nothing was quicker than
thought, said: “I know something that is quicker than thought.” “What
is it, Johnny?” asked his pa. “Whistling,” said Johnny. “When I was
in school yesterday I whistled before I thought, and got caned for
it, too.”


125. The number of men in both fronts of two columns of troops A and
B, when each consisted of as many ranks as it had men in front, was

columns was 91. Required: the number of men in each column.


RUNNING THROUGH HIS FORTUNE.

126. A man inheriting money spends on the first day 19s., twice that
amount on the next, and 19s. additional every day till he exhausts
his fortune by spending on the last day £190 by way of having a real
good time of it and treating his friends to a good “blow out.” What
amount of money had he left to him at the start?


127. A shopkeeper makes on a certain article the first day a profit

he selling the article?


“AWFUL SACRIFICE.”

One of those generous, disinterested, self-sacrificing tradesmen,
having stuck upon every other pane of glass in his window,
“Selling-off,” “No reasonable offer refused,” “Must close on
Saturday,” offered himself as bail, or security, in some case
which was brought before a magistrate, when the following dialogue
ensued:--The magistrate asking him if he was worth £200, “Yes,” he
replied. “But you are about to remove, are you not?” “No.” “Why, you
write up, ‘Selling-off.’” “Yes, every shopkeeper is selling off.”
“You say, ‘No reasonable offer will be refused.’” “Well, I should be
very unreasonable if I did refuse such offers.” “But you say, ‘Must
close on Saturday.’” “To be sure; you would not have me open on
Sunday, would you?”


128. A man dying left his property of £10,000 to his four children,
aged respectively 6, 8, 10, and 12 years, on the understanding that
each on attaining his majority shall receive the same amount of
money, comp. interest at the rate of 4½ per cent. being allowed.
What is the amount of the £10,000 payable to each?


A WASTE OF TIME.

A little boy spent his first day at school. “What did you learn?” was
his aunt’s question. “Didn’t learn nothing.” “Well, what did you do?”
“Didn’t do nothing. There was a woman wanting to know how to spell
‘cat,’ and I told her.”


An English School-boy’s Essay on Australia.

“Part of Austrailya is vague. It ust to be used by the English to
keep men on that was not bad enough to be killed. Some farms would
raise as much as five hundred thousand. The English long ago ust to
send their prisoners there when they did anything not worth hanging.

“Austrailya is a vast Country, and the biggest Island on the surface
of the Earth. It has all its bad men and they have found a great many
Gold and Diamonds there, and Sidney is one of the Chief Countries in
it which is in new south Wales.

“It used to be used for purposes of Exploration, but it has no
interior, and you can’t explore it. Sometimes it is called Antipides,
because everything is upside down there. The chief products are Wool
and Gold and other Exports and the Austrailyan eleven come from
there. The Climate is hot in the Summer and not so in the Winter,
which causes drowts and sweeps all the sheep away and the banks break.

“It was discovered by Captain Cook who captured it from the Dutch.
There are no wild Animals there except the Kangaroo, they fly
through the air with great skill and then they return again right to
your feet. The natives are coloured Black and they call themselves
Aboriginels, they subsist on bark and other food they do no work and
chop wood for a miserable living and can smell the ground like a
dog. When we go there they call us new Chums. They have no form of
Worship, and pray for rain, but a belief in Federashun because they
want to be joined together.

“Their only amusement is Co-robbery. It is celebrated for
Bushrangers and the Melbourne Cup which sticks people up and takes
from them all they have got.

“Austrailya has a lot of aliasses, one is new Holland and afterwards
it was called Pollynesia, and Van Demon and Oceana but sir Henry
Parks called it Austrailya on his Death-bed. You can go to it in a
ship but it is joined to Great Britain by a cable.”

and B when they were married, and the age of the youngest child now
that they have been married 14 years.


AN APPALLING “SUM.”

At a school, a short time back, the pupils were given, as a home
lesson, the task of subtracting from 880,788,889 the number 629 so
often till nothing remained.

The boys worked on for hours without any perceptible diminution of
the figures, and at length gave up the task in despair. Some of the
parents then tried their hands, with no better success. For, in order
to work out the sum, the number 629 would have to be subtracted
1,400,300 times, leaving 189 as a remainder.

Working 12 hours a day, at the rate of 3 subtractions per minute, it
would take over 1 year and 9 months to complete the sum which had
been set the poor lads for their home lesson.


A MILITARY LUNCHEON.

135. A certain number of Volunteers--namely, Commissioned Officers,
Non-commissioned Officers, and Privates had a dinner bill to pay;
there were, it seemed, half as many more Non-Com. Officers as Com.,
one-third as many more Privates as Non-Com. Officers, and they agreed
that each Commissioned Officer should pay one-third as much again
as each Non-Com., and each Non-Com. one-fifth as much again as each
Private; but 1 Commissioned and 2 Non-Com. Officers slipped away
without paying their portion (5s.), each of the others had to pay in
consequence 4d. more. What was the amount of the bill, and the number
of each present?


Twice the half of 1½? Ask your friends--it bothers them.


The Problem Easily Solved.

“Do you see that row of poplars on the other bank standing apparently
at equal distances apart?” asked a grave-faced man of a group of
people standing by a river.

The group nodded assent.

“Well, there’s quite a story connected with those trees,” he
continued. “Some years ago there lived in a house overlooking the
river a very wealthy banker, whose only daughter was beloved by a
young surveyor. The old man was inclined to question the professional
skill of the young rod and level, and to put him to the test directed
him to set out on the river shore a row of trees, no two of which
should be any further apart than any other two. The trial proved
the lover’s inefficiency, and forthwith he was forbidden the house,
and in despair drowned himself in the river. Perhaps some of you
gentlemen with keen eyes can tell me which two trees are furthest
apart?”

The group took a critical view of the situation, and each member
selected a different pair of trees. Finally, after much discussion,
an appeal was made to the solemn-faced stranger to solve the problem.

“The first and the last,” said he, calmly, resuming his cigar and
walking away with the air of a sage.


136.
       Twice five of us are eight of us, and two of us are three,
       And three of us are five of us--now how can all this be?

       Eight of us are five of us and five of us are four.


“EXPRESSIONAL” MEASURES.

The table of measures says that 3 barleycorns make 1 inch--and so
they do. When the standards of measures were first established 3
barleycorns, well-dried, were taken out and laid end to end, and
measured an inch.

The “hairbreadth” now used indefinitely for infinitesimal space, was
a regular measure, 16 hairs laid side by side equalling 1 barleycorn.

The expression “in a trice,” as everyone knows, means a very short
space of time. The hour is divided into 60 minutes, the minute into
60 seconds, and the second into 60 “trices.”


A CHALLENGE.

137. A lady belonging to the W.C.T.U. was endeavouring to persuade a
gentleman friend of hers to give up the drink; he replied, “I will
sign the pledge if you tell me how many glasses of beer did I drink
to-day if the difference between their number and the number of times
the square root of their number is contained in 2 be equal to 3.”


MEMORY SYSTEM.

TEACHER--“In what year was the battle of Waterloo fought?”

PUPIL--“I don’t know.”

TEACHER--“It’s simple enough if you only would learn how to
cultivate artificial memory. Remember the twelve apostles. Add half
their number to them. That’s eighteen. Multiply by a hundred. That’s
eighteen hundred. Take the twelve apostles again. Add a quarter of
their number to them. That’s fifteen. Add to what you’ve got. That’s
1815. That’s the date. Quite simple, you see, to remember dates if
you will only adopt my system.”


A GLOBE TROTTER.

138. Everyone knows that in a race on a circular track the competitor
who has the “inside” running has the least ground to cover, hence the
great desire of cyclists, jockeys, &c., to “hug the fence.”

Now a gentleman, six feet high, starts walking round the Earth on
the equator; his feet, therefore, have the inside running. Find out
how much further his head travels than his feet in performing this
wonderful journey? taking the circumference of the globe at the
equator to be 25,000 miles.

A Cure for Big Words.

Here is a good story of how a father cured his son of verbal
grandiloquence. The boy wrote from college, using such large
words that the father replied with the following letter:--“In
promulgating your esoteric cogitations, or articulating superficial
sentimentalities, and philosophical or pscyhological observations,
beware of platitudinous ponderosity. Let your conversation possess
a clarified conciseness, compacted comprehensibleness, coalescent
consistency, and a concatenated cogency. Eschew all conglomerations
of flatulent garrulity, jejune babblement, and asinine affectations.
Let your extemporaneous descantings and unpremeditated expatiations
have intelligibility, without rhodomontade or thrasonical bombast.
Sedulously avoid all polysyllabical profundity, pompous prolixity,
and ventriloquial vapidity. Shun double entendre and prurient
jocosity, whether obscure or apparent. In other words, _speak
truthfully, naturally, clearly, purely, but do not use big words_.”


142. With a pair each of four different weights, 1 lb. up to 170 lbs.

COMPLIMENTARY, VERY!

EDITOR--“Did you see the notice I gave you yesterday?”

SHOPKEEPER--“Yes, and I don’t want another. The man who says
I’ve got plenty of grit, and that the milk I sell is of the first
water, and that my butter is the strongest in the market, may mean
well, but he is not the man whose encomiums I value.”


145. A vintner draws a certain quantity of wine out of a full vessel
that holds 256 gallons, and then filling the same vessel with water
draws off the same quantity of liquor as before, and so on for four
draughts, when only 81 gallons of pure wine is left. How much wine
did he draw each time?


146. A man has 4 horses, for which he gave £80; the first horse cost

amount does each receive in full in the proportion named?


RAILWAY-SHUNTING PUZZLE.

148. A locomotive is on the main line of railway; the trucks marked
1 and 2 are on sidings which meet at the points, where there is room
for one truck only and not for the locomotive. It is desired to
reverse the position of the trucks--that is, put 1 where 2 is, and
2 where 1 is, and yet leave the locomotive free on the main line.
This must be done by means of the locomotive only, either pulling
or pushing the trucks--it may be between them, thus pulling one and
pushing the other--but no truck must move without the locomotive.

[Illustration]

In working this puzzle out, it would be best to draw the diagram
on an enlarged scale, and have articles to represent the trucks and
locomotive.


149. In a public square there is a fountain containing a quantity

and one-thirteenth of the remainder, the third 300 quarts and
one-thirteenth, and so on, until the fountain was emptied. How many
quarts were there in the fountain?

are there in each company?


A GRAVE MISTAKE.

A Scotch tradesman, who had amassed, as he believed, £4000, was
surprised at his old clerk’s showing by a balance-sheet his fortune
to be £6000. “It canna be--count again,” said the old man. The clerk
did count again, and again declared the balance to be £6000. Time
after time he cast up the columns--it was still a 6, and not a 4,
that rewarded his labours. So the old merchant, on the strength of
his good fortune, modernised his house, and put money in the purse
of the carpenter, the painter, and the upholsterer. Still, however,
he had a lurking doubt of the existence of the extra £2000; so one
winter’s night he sat down to give the columns “one count more.” At
the close of his task he jumped up as though he had been galvanised,
and rushed out in a shower of rain to the house of the clerk, who,
capped and drowsy, put out his head from an attic window at the sound
of the knocker, mumbling, “Who’s there, and what d’ye want?” “It’s
me, ye scoundrel!” exclaimed his employer. “Ye’ve added up the year
of our Lord amang the poons!”


PROBLEM FOR PRINTERS.

each page contains 2 lines less, and each line 3 letters less, the
number of letters in each page would be 145 less than before. Find
the number of lines in each page, and the number of letters in each
line.


THE INCOME TAX.

153. The charge on a major income is the same in amount as that on a

the rate imposed on the overplus of a major income is 4 per cent., so
that on a composite income of the major and minor the charge would be
£3 8s. Required the major and minor incomes.


“Your Money or Your Life!”

154. Two gentlemen, A and B, with £100 and £48 respectively, having
to perform a long journey through a lonely part of the country, agree
to travel together for purposes of safety; they are, however, taken
unawares by a gang of bushrangers who, calling upon them to “bail
up,” ease them of some of their cash. The leader of the gang was
satisfied with taking twice as much from A as from B, and left to A
three times as much as to B. How much was taken from each?

GEOMETRICAL MUSIC.

    · A point, my boys, is that which has no length, breadth,
          or dimension.
    -- A line has length, and yet is but a point drawn in extension.
    All lines have names expressing some distinguishing particular.
    As: horizontal, parallel, oblique, and perpendicular.

                            A pretty science mathematics is to know.

    The lines called parallel are those which, drawn in one direction,
    Continued to infinity, will never make bisection.
    The thing perhaps sounds odd, but if you entertain a doubt, boys,
    I’ll draw the lines, ====== now take your slates, and work the
    problem out, boys.

                _Chorus of Pupils._               Oh! dear! no!

ENGLISH HISTORY.

A school examination paper contained the question:--“Write down all
you know about Henry VIII,” and one of the small boys answered as
follows:--

“King Henry 8 was the greatest widower that ever lived. He was born
at Anne Domini in the year 1066. He had 510 wives besides children.
The first was beheaded and afterwards executed, and the second was
revoked. She never smiled again. But she said the word ‘Calais’ would
be found on her heart after death. The greatest man in this reign
was Lord Sir Garret Wolsey--named the Boy Bachelor. He was born at
the age of fifteen unmarried. Henry 8 was succeeded on the throne by
his great-grandmother, the beautiful Mary, Queen of Scots, sometimes
called Lady of the Lake or the Lay of the Last Minstrel.”

THE VALUE OF HOME LESSONS.

Two teachers of languages were discussing matters and things relative
to their profession.

“Do your pupils pay up regularly on the first of each month?” asked
one of them.

“No, they do not,” was the reply; “I often have to wait weeks and
weeks before I get my pay, and sometimes I don’t get it at all. You
can’t well dun the parents for the money.”

“Why don’t you do as I do? I always get my money regularly.”

“How do you manage it?”

“It is very simple. For instance, I am teaching a boy French, and
on the first day of the month his folks don’t send the amount due
for the previous month. In that case I give the boy the following
exercise to translate and write out at home:--‘I have no money. The
month is up. Hast thou any money? Have not thy parents any money? I
need money very much. Why hast thou brought no money this morning?
Did thy father not give thee any money? Has he no money in the
pocket-book of his uncle’s great aunt?’ This fetches them. Next
morning that boy brings the money.”

for a journey of 100 miles, the total cost of the eight tickets
being £3 2s. 6d., find the charge per mile for each first-class and
second-class ticket.


HUMILITY.

In a certain street are three tailors. The first to set up shop hung
out this sign--“Here is the best tailor in the town.” The next put
up--“Here is the best tailor in the world.” The third simply had
this--“Here is the best tailor in this street.”


“On the Wallaby.”

176. Four sundowners called at a station and asked for rations.
“Well,” said the manager, “I have a job that will take 200 hours to
complete; if you want to do it, you can divide the work and the money
among yourselves as you see fit.” The sundowners agreed to do the
work on these conditions. “Now, mates,” said the laziest of them,
“it’s no good all of us doing the same amount of work. Let’s toss
up to see who shall work the most hours a day, and who the fewest.
Then let each man work as many days as he does hours a day.” This
was agreed to; but the proposer took good care that chance should
designate him to do the least number of hours of work. How were the
200 hours put in so that each man should work as many hours as days,
and yet no two men work the same number of hours?


177. On multiplying a certain number by 517 a result is obtained
greater by 7,303,535 than if the same number had been multiplied
by 312. How much greater still would be the result if 811 were the
multiplier instead of 312?


A “CATCH.”

178. Six ears of corn are in a hollow stump. How long will it take a
squirrel to carry them all out if he takes but three ears a day?


NUMBER 7.

The number 7 has always been considered the most sacred of all our
figures. Its prominence in the Scriptures is very remarkable, from
Genesis--where we read that the seventh day was consecrated as a day
of rest and repose--to Revelations--where we find the seven churches
of Asia; seven golden candlesticks; the book with seven seals; the
seven angels with seven trumpets; seven kings; seven thunders; seven
plagues, &c., &c., its frequent occurrence is most striking.

The Ancients paid great respect to the seven mouths of the Nile.
The seven rivers of Vedic India; seven wonders of the world; seven
precious stones; seven notes of music; seven colours of the rainbow,
&c., &c. The “Lampads seven that watch the Throne of Heaven” led
the Chaldeans to esteem the unit 7 as the holiest of all numbers,
thereupon they established the week of seven days, and built their
temples in seven stages. The temples and palaces of Burma and China
are seven-roofed.

In modern times this number has kept up its reputation. Shakespeare
paid special regard to it; the “seven ages” and every multiple of it
is supposed to be a critical or important period in one’s life.

A modern philosopher as follows apportions--

MAN’S FULL EXTREME.

  7 years in childhood, sport and play,   (7)
  7 years in school from day to day,     (14)
  7 years at trade or college life,      (21)
  7 years to find a place and wife,      (28)
  7 years to pleasure’s follies given,   (35)
  7 years to business hardly driven,     (42)
  7 years for some wild-goose chase,     (49)
  7 years for wealth, a bootless race,   (56)
  7 years of hoarding for your heir,     (63)
  7 years in weakness spent and care,    (70)
  And then you die and go--you know not where.

Very many superstitious and curious ideas have been and still are
connected with all our figures. For those interested in this subject
see page 146--“How To Become Quick At Figures” (Student’s Edition).


“What’s the difference,” asked a teacher in arithmetic, “between one
yard and two yards?” “A fence,” said Tommy Yates. Then Tommy sat on
the ruler 14 times.


179. What relation is a woman to me who is my mother’s only child’s
wife’s daughter?


THE ADVANTAGES OF SKILFUL BOOK-KEEPING.

If a merchant wishes to get pretty deeply in debt, and then get rid
of his liabilities by bankruptcy--if, in fact, he proposes to himself
to go systematically into the swindling business, and engage in
wholesale pecuniary transactions without a shilling of his own, the
first thing he should take care to learn would be the whole art of
book-keeping.

From what may occasionally be seen of the reports of the proceedings
in bankruptcy, it is found that _well kept books_ are regarded as
quite a test of honesty, and though assets may have disappeared or
never have existed, though large liabilities may have been incurred
without any prospect of payment, the bankrupt will be complimented
on the straight look of his dealings, if he has shown himself a good
book-keeper.

To common apprehension it would seem that well kept books would only
help to show a reckless trader the ruinous result of his proceedings,
and that while the man _without_ books might flatter himself that
all would come out right at last, the man with exact accounts would
only get into hot water with his eyes open. If a man may trade on
the capital of others without any of his own, and get excused on the
ground that he has kept his books correctly, it is difficult to see
why a thief who steals purses, &c., may not plead in mitigation of
punishment that he has carefully booked the whole of his transactions.

It would be interesting to know the effect of producing a ledger
on a trial for felony, as well as curious to observe whether a
burglar would be leniently dealt with on the ground that his
house-breaking accounts gave proof of his experience in the science
of “double-entry.”

Therefore it would be well for those interested to procure copies of
“RE ACCOUNTS” and “ADVANCED THOUGHT ON ACCOUNTS.”


THE FIRM HE REPRESENTED.

A commercial traveller handed a merchant upon whom he had called a
portrait of his sweetheart in mistake for his business card, saying
that he represented that establishment. The merchant examined it
carefully, remarked that it was a fine establishment, and returned it
to the astonished and blushing traveller with the hope that he would
soon be admitted into partnership.


180. A man and a boy being paid for certain days’ work, the man
received 27s., and the boy, who had been absent 3 days out of the
time, received 12s. Had the man, instead of the boy, been absent the
3 days they would both have claimed an equal sum. Find out the wages
of each per day.


181. The extremes of an arithmetical series are 21 and 497, and the
number of terms is 41. What is the common difference?

182. A wine which contains 7½ per cent. of spirit is frozen, and
the ice which contains no spirit being removed the proportion of
spirit in the wine is increased by 8¾ per cent. How much water in
the shape of ice was removed from 504 gallons of the mixture?


THE SHARP SELECTOR.

183. A selector rented a farm, and agreed to give his landlord
two-fifths of the produce, but prior to the time of dividing the corn
the selector used 45 bushels. When the general division was made it
was proposed to give to the landlord 18 bushels from the heap in lieu
of the share of the 45 bushels which the tenant had used, and then to
begin and divide the remainder as though none had been used. Would
this method have been correct?


A GOOD “AD.”

A member of a certain firm appeared in a law court with a complaint
that his partner would sell goods at less than cost price, and he
desired to have him restrained. The defendant utterly denied the
charge, and the case was adjourned for a fortnight. As the plaintiff
went out of court he exclaimed in a tragic tone: “Then the sacrifice
must still go on!” and “I’ll be ruined!” The story was noised
abroad, and the result was that the shop was besieged by customers
every day. There the case ended, for at the end of the fortnight
the plaintiff failed to appear in court, having accomplished his
purpose--advertisement.


184. I give 3 sovereigns for 2 dozen wine at different rates per
dozen, and by selling the cheaper kind at a profit of 15 per cent.
and the dearer at a loss of 8 per cent. I obtain a uniform price for
both. What did each dozen cost me?


185. I have in my garden a shrub that grows 12 inches every day, but
during the night it withers off to half the height that it was at the
end of the previous day. How much short of 2 feet will it be at the
end of a year?


TIT-FOR-TAT.

186. A farmer puts a 3 lb. stone in a keg of butter worth 11d. a
pound. The merchant cheats him out of 1 lb. on the weight, and then
does him out of 1s. 11d. on calico, tobacco, and a shovel. Who is
ahead, and how much?


187. Trains leave London and Edinburgh (400 miles apart) at the same
time and meet after 5 hours; the train which leaves London travels 8
miles an hour faster than that which leaves Edinburgh. At what rate
did the former travel, and at what speed must the latter travel after
they have met, in order that they both may reach their destinations
at the same time?


“GOOD ENOUGH!”

“Will you give me a glass of beer, please?” asked a rather
seedy-looking fellow with an old but well-brushed coat and almost too
shiny a hat. It was produced by the barmaid, frothing over the edge
of the tumbler.

“Thank you,” said the recipient, as he placed it to his lips. Having
finished it in a swallow, he smacked his lips and said, “That is very
good beer--_very_! Whose is it?”

“Why, that Perkins’s----”

“Ah! Perkins’s, is it! Well, give us another glass.”

It was done; and holding it up to the light and looking through it,
the connoisseur said:--

“’Pon my word, it is grand beer--clear as Madeira! What a fine color!
I must have some more of that; give me another glass.”

The glass was filled again, but before putting it to his lips the
imbiber said:--

“_Whose_ beer did you say this was?”

“Perkins’s,” emphatically replied the barmaid.

The contents of the glass was exhausted, as also the vocabulary of
praise, and it only remained for the appreciative gentleman to say,
as he wiped his mouth and went towards the door:--

“Perkins’s beer, is it! I know Perkins very well; I shall see
him soon, and will settle with him for three long glasses of his
incomparable brew. Good morning.”


A Conspiracy.

188. Three gentlemen are going over a ferry with their three
servants, who conspire to rob them if they can get one gentleman to
two of them, or two to three, on either side of the ferry. They have
a boat that will only carry two at once, and either a gentleman or a
servant must bring back the boat each time a cargo of them goes over.
How can the gentlemen get over with all their servants so as to avoid
an attack?


189. Find two numbers whose product is equal to the difference of
their squares, and the sum of their squares equal to the difference
of their cubes?


190. Divide 1400 into such parts as shall have the same ratio as the
cubes of the first four natural numbers.


This was the tempting notice lately exhibited in the window of a
dealer in cheap shirts: “They won’t last long at this price!”


POSTING THE LEDGER.

The well known author of several works on account-keeping, Mr.
Yaldwyn, tells a rather good thing which actually occurred in New
Zealand some time back. Mr. Yaldwyn was at the time engaged examining
the books in one of the offices in a country town, and enquired
from one of the clerks standing near if the ledger were posted.
The person appealed to answered that “he didn’t know,” whereupon
Mr. Y. said that he required it done, and with as little delay as
possible. A few minutes later the same individual came rushing in and
informed him that the ledger was “posted.” Such a piece of “lightning
book-keeping” so surprised Mr. Y. that he further questioned the man,
who replied “You said you wanted the ledger posted, and, begorra, I
posted it.” It then dawned upon Mr. Yaldwyn that the clerk, who was
an Irishman, had actually _posted_ the book in the post office!


THEY MANAGED IT.

[Illustration]

191. Billy and Tommy, two aboriginals, killed a kangaroo in the bush,
and began quarrelling over the weight of the animal. They had no
proper means of weighing it, but, knowing their own weights, Billy
130 lbs. and Tommy 190 lbs., they placed a log of wood across a stump
so that it balanced with one on each end. They then exchanged places,
and, the lighter man taking the kangaroo on his knees, the log again
balanced. What was the weight of the kangaroo?


192. A son asked his father how old he was, and received the
following answer: “Your age is now one quarter of mine, but five
years ago it was only one-fifth.” How old is the father?


193. Place three sixes together so as to make seven.


THE PASSING TRAINS PUZZLE.

194. If through passenger trains running to and from New York and San
Francisco daily start at the same hour from each place (difference
of longitude not being considered) and take the same time--seven
days--for the trip, how many such trains coming in an opposite
direction will a train leaving New York meet before it arrives at San
Francisco?


THE SCHOOL-TEACHER “CAUGHT.”

Two of our Public Schools were engaged playing a football match one
afternoon. The head master of one of them had generously given the
boys a half-holiday; but the gentleman who held the same capacity in
the other school, not being an ardent admirer of Australia’s national
game, refused to do so. When school assembled in the afternoon, a
boy volunteered to ask the master for the desired holiday. When the
question was put, he firmly answered, “No, no!” whereupon the bright
youth called out: “Hurrah! we have our holiday; two negatives make an
affirmative.” The teacher was so pleased at the boy’s sharpness that
he dismissed the school right away.


195. A man arrives at the railway station nearest to his home 1½
hours before the time at which he had ordered his carriage to meet
him. He sets out at once to walk at the rate of four miles an hour,
and, meeting his carriage when it had travelled eight miles, reaches
home exactly one hour earlier than he had originally expected. How
far was his house from the station, and at what rate was his carriage
driven?


“OFF THE TRACK.”

196. A man starts to walk from a town, A, to a town B, a distance by
road of 16 miles, at the rate of 4 miles an hour. There is a point
C on the road, at which the road to B leads away to the right, and
another road at right-angles to this latter goes to the left, “to no
place in particular.” The unwary traveller gets on to this left hand
road, and is walking for 2¼ hours since he left A, before he finds
out his mistake, and he resolves not to go back to the junction,
which is five miles away, but makes straight across the bush to B,
and strikes it exactly. How long did it take to go from A to B?


GAMBLING.

197. Three friends, A, B, and C, sit down to play cards. As a result
of the first game, A lost to each of B and C as much money as they
started to play with; the result of the second game B lost similarly
to each of A and C; and in the third, C lost similarly to each of A
and B;--and they then had 24s. each. What had they each at first?


This Sticks Them Up.

[Illustration]

198. A, who is a dealer in horses, sells one to B for £55. B very
soon discovers that he does not require the animal, and sells him
back to A for £50. Now, A is not long in finding another customer for
the horse: he sells it to C for £60. How much money does A make out
of this transaction?

This question has been the cause of endless discussion and argument.

It might be as well to state that when A first sold the horse to B he
neither made nor lost any money by the deal.


SCRIPTURAL FINANCE.

199. What is the earliest banking transaction mentioned in the Bible?
The answer generally given to this is, “The check which Pharaoh
received on the banks of the Red Sea, crossed by Moses & Co.” There
is still an earlier instance: see if you can find it out.


200. How much tea at 6s. per lb. must be mixed with 12 lbs. at 3s. 8d.
per lb. so that the mixture may be worth 4s. 4d. per lb.?


201. Place 17 little sticks--matches, for instance--making six equal
squares, as in the margin, then remove five sticks and leave three
perfect squares of the same size.

FOR THE JEWELLER.

202. How much gold of 21 and 23 carats must be mixed with 30 oz of 20
carats, so that the mixture may be 22 carats?


LONDON GRAMMAR.

Three cockneys, being out one evening in a dense fog, came up to
a building that they thus described. The first said, “There’s a
_nouse_.” “No,” said the second, “It’s a _nut_.” The third exclaimed
“You’re both wrong; it’s a _nin_!”


203. A draper sold 12 yards of cloth at 20s. per yard, and lost 10
per cent. What was the prime cost?


204. A jockey, on a horse galloping at the rate of 18 miles an hour
on the Flemington racecourse, passes in 30 minutes over the diameter
and curve of a semi-circle. What area does he enclose by the ride?


205. How many trees 20 feet apart cover an acre?

  “Multiplication is vexation,
  Division is as bad.
  The rule of three, it puzzles me,
  And fractions drive me mad.”


MULTIPLY £19 19s. 11¾d. BY £19 19s. 11¾d.

This very old question is continually cropping up, and will continue
to do so as long as men are able to reckon. The answer generally
given is £399 19s. 2d. and a fraction, and the method of working it
out as follows:--

  £19 19s. 11¾d.  = 19199 farthings.

  19199   19199   368601601
  ----- x ----- = --------- and so on.
    960     960      921600

Many adopt the following method:--

  £20 x £20 = £400

                                   £   s    d
                                  400  0    0
          ¼d x ¼d = 1/16   less             1/16
                                 ----------------
                                 £399 19 11-15/16 Ans.

It would be possible to adopt other methods, each of which would give
a different result.

Properly speaking, _this sum cannot be done_.

Multiplication is merely a contracted form of addition: it means
taking a number or quantity a certain number of times. Every
multiplication can be proved by addition. All numbers are _abstract_
or _concrete_--3 is abstract, £3 is concrete.

Two abstract numbers can be multiplied together--as, 4 times 3 = 12.

  Proof: 3
         3
         3
         3
        --
        12

One abstract number and one concrete number can be multiplied
together--as 2s. multiplied by 3 = 6s.

  Proof:   2s.
           2s.
           2s.
           ---
           6s.

Two concrete numbers cannot be multiplied together.

In the example just given, 2s. multiplied by 3, we see it simply
means to write down 2s. three times, and by addition we discover the
answer to be 6s. Suppose the reader lent a friend 2s. on Monday, 2s.
on Tuesday, and 2s. on Wednesday, he has lent 2s. three times, making
6s. lent in all.

Now, we will attempt to multiply 2s. by 3s., but it is impossible
to comprehend how many times is 3s. times. The answer to 2s. x 3s.
usually given is 6s. On the same lines, we multiply 9d. by 10d., and
our answer is--90d., that is 7s. 6d.--a greater product than 2s.
multiplied by 3s.

Although it is stated that two concrete numbers cannot be multiplied
together, it should be borne in mind that we can multiply yards,
feet, and inches, by yards, feet, and inches (length by breadth),
which will result in square or cubic measure: 12 inches make 1 foot,
and 3 feet make one yard, 144 square inches make 1 square foot, &c.
12 pence make 1 shilling, but how many square pence make 1 square
shilling?

The argument generally brought forward in favour of the performance
of this problem is, that when the Rule of Three is applied to
financial questions (such as interests, &c.) money is multiplied by
money.

Example.--If the interest on £10 is 15s., what is the interest on £20?

  As £10 : £20 :: 15s. : _x_

       15
     ____
  10)300
     ----
      30      Ans. 30s.

The multiplication in the above is in appearance only, for all we get
in the Rule of Three is the ratio between the sums of money and this
ratio is an abstract number, and not concrete. On examination we find
the ratio between £10 and £20; that the latter is double, or _two_
times as much as the former, and not £2 times more than it.

We extend a general invitation to all our readers who hold a
different opinion to multiply three pints of Dewar’s Whisky by 6
quarts of soda-water, but in case they might plead inability to
perform this little feat, on conscientious grounds, we will extend
the invitation to three cups of tea by six spoonfuls of sugar. And if
any of them have a few pounds (say £10) in the Savings Bank we would
advise “Don’t _add_ any more deposits, but wait till you have £2,
then proceed to the bank and multiply the £10 by the £2, and prove
to the teller that you have £20 to your account. Be careful to take
no less a sum than £2, or the result might be a little surprising,
for if you take only £1, the teller might argue after he has received
your sovereign that “ten ones are ten,” and then your £10 would
remain the same.”


206. What is the difference between six dozen dozen and half a dozen

A TELL-TALE TABLE.

There is a good deal of amusement in the following table. It will
enable you to tell how old the young ladies are. Ask a young lady to
tell you in which column or columns her age is found, add together
the figures at the top of the columns in which she says her age is,
and you have the secret. Suppose a young lady is 19. You will find
that number in the first, second and fifth columns; add the first
figures of these columns--1, 2 and 16--and you get the age.

EUCLID.--THE FAMOUS FORTY-SEVENTH.

“_In any right-angled triangle, the square which is described
upon the side opposite to the right-angle is equal to the squares
described upon the sides which contain the right-angle._”

Here is a simple way of proving this proposition. Although perhaps
not exactly scholastic, it is none the less interesting.

Draw an exact square, whose sides measure 7 in.; then divide it into
49 square inches. Having done this, cut the figure in following the
big lines as shown by Fig 1. It will be observed that C is a complete
square, and that A and B will form a square: but as D is 1 in. short
of being a square, it is necessary to cut a square inch and add it on.

[Illustration: Fig. 1.]

[Illustration: Fig. 2.]

Then construct a right-angled triangle as shown by Figure 2.

We then see that the sum of the two small squares is equivalent to
the large square.

      D contains  9 small squares.
  A & B   do.    16     do.
                 --
                 25

And as we see that C has 25 small squares, it is thus proved that the
sum of the squares upon the sides which contain the right angle are
equal to the squares upon the side opposite the right angle.

THE GREAT FISH PROBLEM.

209. There is a fish the head of which is 9 in. long, the tail is as
long as the head and half the back, and the back is as long as the
head and tail together. What is the length of the fish?


210. How may 100 be expressed with four nines?


211. Two shepherds, A and B, meeting on the road, began talking of
the number of sheep each had, when A said to B, “Give me one of your
sheep, and I will have as many as you.” “Oh, no!” replied B; “give me
one of yours, and I will have as many again as you.” How many sheep
had each?


A BRICK PUZZLE.

ONE FOR BUILDERS, CONTRACTORS, &C.

212. Suppose the measurements of a brick to be:--Length, 9 in.;
breadth, 4½ in.; depth, 3 in. How many “stretchers, headers and
closures” can be cut out of one, and what would be the face area of
same?

For the benefit of the uninitiated we might say that

  “stretcher” = length of brick x depth
  “header”    = breadth         "
  “closure”   = half-breadth    "


213. A woman has a basket of 150 eggs; for every 1½ goose egg she
has 2½ duck eggs and 3½ hen eggs. How many of each had she?


The Great Chess Problem.

THE KNIGHT MOVE.

214. Move the Knight over all the 64 squares of the chess board so
as to successively cover each square and, of course, not enter any
square twice. This problem has always proved to be an interesting
one. Mathematicians throughout all ages have devoted a good deal of
time to it. To chess players it should be especially attractive.

ANSWER THIS.

217. Suppose it were possible for a man in Sydney to start on Sunday
noon, January 1st, and travel westward with the sun, so that it might
be in his meridian all the time, he would arrive at Sydney next day
at noon, Monday, Jan. 2nd. Now, it was Sunday noon when he started,
it was noon with him all the way round, and is Monday noon when he
returns. The question is, at what point did it change from Sunday to
Monday?


218. Start with 1 and keep on doubling for eight times, thus giving

together, horizontally, vertically, or diagonally, the product of
each row will be the cube of the number which must go in the centre
of the square.


The happiest year in a man’s life is 40; for then he can XL.


Bound to Win!

219. A certain gentleman, who was employed in one of our city
offices, purchased THE DOCTRINE OF CHANCE, which he studied
in his spare time, with the result that he sent in his resignation to
the head of the firm in order to try his luck on the racecourse.

At the first meeting he attended, there were only three horses in a
race. His brother bookmakers were crying out the odds--

“Two to 1 bar one.”

The odds on this latter horse which was “barred” he discovered to be
6 to 4 _on_. He determined to give far more liberal odds, and called
out--

“Even money, 2 to 1, and 3 to 1.”

How could he give such odds, and yet win £1, _no matter which horse
wins the race_?

AN INCH OF RAIN.

How many people really consider what is contained in the expression?
Calculated, it amounts to this:--An acre is equal to 6,272,640 square
inches; an inch deep of water on this area will be as many cubic
inches of water, which, at 277·274 inches to the gallon, is 22622·5
gallons. The quantity weighs 226,225 lbs. Thus, an “inch of rain” is
over 100 tons of water to the acre.

“THE EVIDENCE YOU NOW GIVE, &c., &c.”

221. Smith, Brown, and Jones were witnesses in a law case. The
first-named gentleman swore that a certain thing occurred; Brown, on
being called, confirmed Smith’s statement, but Jones denied it. They
are known to tell the truth as follows:--

  Smith, once in  3 times
  Brown,   "   "  5   "
  Jones,   "   " 10   "

What is the probability that the statement is true?

Which Hand is It In?

[Illustration]

A person having in one hand a piece of gold, and in the other a piece
of silver, you may tell in which hand he has the gold, and in which
the silver, by the following method:--

Some even number (such as 8) must be given to the gold, and an odd
number (such as 3) must be given to the silver; after which, tell the
person to multiply the number in the right hand by any even number
whatever, and that in the left hand by an odd number; then bid him
add together the two products, and if the whole sum be odd, the gold
will be in the right hand and the silver in the left; if the sum be
even, the contrary will be the case.

To conceal the artifice better, it will be sufficient to ask whether
the sum of the two products can be halved without a remainder--for in
that case the total will be even, and in the contrary case odd.


222. Which is the heavier, and by how much--a pound of gold or a
pound of feathers; an ounce of gold or an ounce of feathers?


223. Plant an orchard of 21 trees, so that there shall be 9

227. A man and his wife lived in wedlock, one-third of his age and
one-fourth of hers. Now, the man was eight years older than his wife
at marriage, and she survived him 20 years. How old were they when
married?


TO PROVE THAT YOU HAVE ELEVEN FINGERS.

Count all the fingers of the two hands, then commence to count
backwards on one hand, saying, “10, 9, 8, 7, 6” (with emphasis on
the _6_), and hold up the other hand saying, “and 5 makes 11.” This
simple deception has often puzzled many.


228. A man travelled a certain journey at the rate of four miles an

233.
       Suppose a bushel to be exactly round,
       And the depth, when measured, eight inches be found;
       If the breadth 18·789 inches you discover,
       This bushel is legal all England over:
       But a workman would make one of another frame,
       Seven inches and a half the depth of the same;
       Now say of what length must the diameter be,
       That it may with the former in measure agree.

Science, Paris, says that the most skilful calculator could not in
less than a month find within a unit the cube root of

A PROBLEM THAT WORRIED THE ANCIENTS.

Many profound works have been written on the following famous
problem:--

“When a man says ‘I lie,’ does he lie, or does he not? If he lies he
speaks the truth; if he speaks the truth he lies.”

Several philosophers studied themselves to death in vain attempts to
solve it. Reader, have a “go” at it.


THE CABINET MAKER’S PUZZLE.

234. A cabinet maker has a circular piece of veneering with which he
has to veneer the tops of two oval stools; but it so happens that the
area of the stools, exclusive of the hand-holes in the centre and
that of the circular piece, are the same. How must he cut his veneer
so as to be exactly sufficient for his purpose?


THE ARITHMETICAL TRIANGLE.

  1
  2,  1
  3,  3,  1
  4,  6,  4,  1
  5, 10, 10,  5,  1
  6, 15, 20, 15,  6,  1
  7, 21, 35, 35, 21,  7,  1
  8, 28, 56, 70, 56, 28,  8,  1

Write down the numbers 1, 2, 3, &c., as far as you please in a
column. On the right hand of 2 place 1, add them together and place
3 under the 1; the 3 added to 3 = 6, which place under the 3, and
so on; this gives the second column. The third is found from the
second in a similar way. By the triangle we can determine how many
combinations can be made, taking any number at a time out of a larger
number. For instance, a group of 8 gentlemen agreed that they should
visit the Crystal Palace 3 at a time, and that the visits should be
continued daily as long as a different three could be selected. In
how many days were the possible combinations of 3 out of 8 completed?

METHOD: Look down the first column till you come to 8, then
see what number is horizontal with it in the third column, viz., 56.
(For the method usually adopted for working out calculations like the
above, see DOCTRINE OF CHANCE.)


235. Why is a pound note more valuable than a sovereign?


KEEPING UP STYLE.

236. A certain hotelkeeper was never at a loss to produce a large
appearance with small means. In the dining-room were three tables,
between which he could divide 21 bottles of wine, of which 7 only
were full, 7 half-full, and 7 apparently just emptied, and in such a
manner that each table had the same number of bottles and the same
quantity of wine. How did he manage it?


A DOMINO TRICK.

Ask the company to arrange the whole set of dominoes whilst you are
absent in any way they please, subject, however, to domino rules--a
6 placed next to a 6, a 5 to a 5, and so on. You now return and
state that you can tell, without seeing them, what the numbers are
at either end of the chain. The secret lies in the fact that the
complete set of 28 dominoes, arranged as above-mentioned, forms a
circle or endless chain. If arranged in a line the two end numbers
will be found to be the same, and may be brought together, completing
the circle. You privately abstract one domino (not a double), thus
causing a break in the chain. The numbers left at the ends of the
line will then be the same as those of the “missing link” (say the
3-5 or 6-2.) The trick may be repeated, but you must not forget to
exchange the stolen domino for another.


237. A busman not having room in his stables for eight of his horses
increased his stable by one half, and then had room for eight more
than his whole number. How many horses had he?


AN ANCIENT QUESTION.

238. “Tell us, illustrious Pythagoras how many pupils frequent thy
school?” “One-half,” replied the philosopher, “study mathematics, one
fourth natural philosophy, one-seventh observe silence, and there are
3 females besides.” How many had he?


EVADING THE QUESTION.

239. A lady being asked her age, and not wishing to give a direct
answer, said, “I have nine children, and three years elapsed between
the birth of each of them. The eldest was born when I was 19 years
old, and the youngest now is exactly 19.” How old was she?


A ’CENTAGE “CATCH.”

240. A man sells a diamond for £60; the number expressing the profit
per cent. is equal to half the number expressing the cost. What was
the cost?


241. Having 5½ hours to spare, how far may I go out by a coach at
the rate of 8 miles an hour so that I may be back in time, walking at
the rate of three miles an hour?


The Cross Puzzle.

[Illustration]

242. Cut out of a piece of card five pieces similar in shape and
proportion to the annexed figures.

  1 piece  similar to 1
  3 pieces    "    "  2
  1 piece     "    "  3

These five pieces are then to be so joined as to form a cross like
that represented by 4.


Irish Counting.

An Irishman who had lately arrived in the colony was employed as
handy man at one of our large suburban mansions. The lady of the
house, hearing that some midnight thief had walked off with some of
her prize poultry, desired Pat to count them as speedily as possible
and to inform her how many there were; he accordingly left off
cleaning the buggy, and proceeded to enumerate the feathered bipeds.
The lady, getting impatient of waiting for him, repaired to the
poultry yard, and noticing him chasing a small chicken, enquired,
“Pat, whatever are you doing!” when the Irishman replied; “I’ve
counted all the chickens except this one; but the little varmint
won’t stand still till I count him.”


THE JEW “JEWED.”

243. An old Jew took a diamond cross to a jeweller to have the
diamonds re-set, and fearing that the jeweller might be dishonest
he counted the diamonds, and found that they numbered 7 in three
different ways. Now, the jeweller stole two diamonds, but arranged
the remainder so that they counted 7 each way as before. How was it
done?

      7
      6
  7 6 5 6 7
      4
      3
      2

244. A person wishing to enclose a piece of ground with palisades
found that if he set them a foot apart that he should have too few by
150, but if he set them a yard apart he should have too many by 70.

245. A mechanic is hired for 60 days on consideration that for each
day he works he shall receive 7s. 6d., but for each day he is idle he
shall pay 2s. 6d. for his board, and at the end he receives £6. How
many days did he work?


246. Take one from nineteen and leave twenty.


THE CAMEL PROBLEM.

[Illustration]

247. An Arab Sheik, when departing this life, left the whole of his
property to his three sons. The property consisted of 17 camels, and
in dividing it the following proportions were to be observed:--

The oldest son was to have one-half of the camels, the second son
one-third, and the youngest son one-ninth; but it was provided that
the camels were not, on any account, to be injured, but to be divided
as they were--living--between the three sons.

Thereupon, a great argument ensued. The eldest son claimed 8½
camels. The second insisted upon receiving 5⅔ of a camel; while
the youngest son would not be comforted with less than 1-8/9 of a
camel. The Cadi (or Judge) happened to appear on the scene. To him
the matter was explained. Without a moment’s hesitation he gave his
decision--a decision by which the claims of all three contestants
were fully satisfied.

How did the Cadi settle this knotty question?


248. A grocer has 6 weights--each one twice as much as the one before
it in size. If he weighed the first five against the largest, it (the
largest) would only be 2 lbs. heavier than the combined weights of
the rest. What are the weights?


249. A squatter said to a new manager, whom he wished to test in
arithmetic: “I have as many pigs as I have cattle and horses, and
if I had twice as many horses I should then have as many horses as
cattle, and I should also have 13 more cattle and horses than pigs.”
How many of each had he?


250. A gentleman a garden had, five score[2] long and four score broad;
     A walk of equal width half round he made, which took up half the
            ground--
     You skilful in Geometry, tell us how wide the walk must be.

[2] Feet.


251. Two boys, meeting at a farmhouse, had a mug of milk set down
to them; the one, being very thirsty, drank till he could see the
centre of the bottom of the mug; the other drank the rest. Now, if
we suppose that the milk cost 4½d., and that the mug measured 4
inches diameter at the top and bottom, and 6 inches in depth, what
would each boy have to pay in proportion to the milk he drank?


Weight-for-Age Problem.

252. There are 6 children seated at a table whose total ages amount
to 39 years. Tom, who is only half the age of Jack (the oldest) is
seated at the top, with Bob--who is a year older than him--next;
whilst Fred, who is four-fifths the age of Jack, is at the foot with
James, who is 1 year younger than Jack, next, him; the youngest, who
is a baby, is one-eighth the age of her brother Fred. Find the ages
of each, and weight of Fred, and by placing him third from the top
his initial and surname. You must express the ages in words, and use
the initial letters.


253.   A flagstaff there was whose height I would know,
       The sun shining clear straight to work I did go.
       The length of the shadow, upon level ground,
       Just sixty-five feet, when measured I found;
       A pole I had there just five feet in length--
       The length of its shadow was four feet one-tenth
       How high was the flagstaff I gladly would know;
       And it is the thing you’re desired to show.


254. Put 4 figures together to equal 30, and the same figures to

Although this is a very old puzzle it is often the cause of much
amusement.


GENEROUS.

262. A gentleman, having a certain number of shillings in his
possession, made up his mind to visit 17 different barracks and treat
the soldiers, and he did so in the following manner:--On going into
the first barracks, he gave the sentry one shilling and then spent
half of his shillings in the canteen amongst the soldiers, and on
coming out of barracks again he gave the sentry another shilling;
he repeated the same until he had finished with the seventeenth
barracks, and had no more shillings left. How many had he when he
commenced?

twelve, of course.” Then ask again, “Well, how many half-penny ones?”
He is almost sure to reply, “Twenty-four.”


Before he settles his account with nature, man charges the debit

THE PUZZLE ABOUT THE “PROFITS.”

Perhaps there is no form of commercial calculation so confusing
and so little understood as that of mercantile profits. It might
surprise many to state, nevertheless it is perfectly true, that it is
impossible to buy goods and sell them to show a profit as great as
100 per cent.

The correct method to calculate profit is to reckon on the
_return_--the price received for the goods sold--_not on the cost
price_, and as it is impossible to sell goods at 100 per cent.
discount, so also goods cannot be sold to show that percentage of
profit, unless they actually cost nothing.

Some time ago, in New Zealand, a well-known boot manufacturer had a
“GREAT DISCOUNT SALE.“ He had large posters displayed on the windows
of his shops, and advertisements in the newspapers, announcing the
fact that 5s. in the £ would be allowed as discount to all customers.
The profit he usually obtained in the ordinary way of trade was 25
per cent., and having had a good season, he was prepared to sell off
the balance of his stock at cost price. The selling price of his
goods was marked in plain figures. A pair of boots which cost him 8s.
was marked 10s., thus showing a profit of 2s., which he considered to
be 25 per cent. (2s. being a quarter of 8s.) Instructions were issued
to all his employees engaged in selling to deduct a quarter from the
marked price, the result being that a pair of boots which cost 8s.,
and marked 10s., was being sold at 7s. 6d. (2s. 6d., the quarter of
the marked price being deducted from 10s.) Although he imagined he
was getting 25 per cent. profit, he was in reality receiving only 20
per cent. It was not long before the posters were altered, announcing
that 4s. in the £ would be allowed to his customers.

The following question was asked some little time ago;--If a chemist
sold a bottle of medicine for 2s. 6d., which cost him 2½d., what
percentage would be his profit?

Many work out the problem and answer 1100 per cent., but this answer
is incorrect. He received 2s. 6d. for that which cost him 2½d.,
accordingly there was a profit of 2s. 3½d. We must now find out
what percentage is the latter amount of the selling price, 2s. 6d.,
and we discover that it is 91⅔ per cent.


266. A pork butcher buys at auction £100 worth of bacon at 4d. per
lb. and sells it at 8d. per lb.; also £100 worth at 8d. per lb.,
which he sells for 4d. per lb. Does he lose or gain? And if so how
much.


“THE JUMPING FROG.”

267. A frog, sitting on one end of a log eight feet long, starts to
jump into a pond at the opposite end. With his first jump he clears
half the distance, the second jump half the remaining distance, and
so on. How many jumps does he take before entering the pond?


OBLONG PUZZLE.

268. Cut out of a piece of cardboard fourteen pieces of the same
shape as those shown in the diagram--the same number of pieces as is
there represented--and then form an oblong with them.

269. If a man can load a cart in five minutes, and a friend can load
it in two and a half minutes, how long will it take them both to load
it, both working together?


270. A gentleman on being asked how old he was, said that if he did
not count Mondays and Thursdays he would be 35. What was his actual
age?


TOO SMART FOR DAD.

“Pa,” said a boy from school, “How many peas are in a pint?” “How can
anybody tell that, foolish boy?” “I can every time. There is just one
‘p’ in pint the world over.” He was sent off to bed early.


SIMPLE PROPORTION.

271. If it takes three minutes to boil one egg, how long will it take
to boil two?


“PUNCH’S” MONEY VAGARIES.

The early Italians used cattle as a currency instead of coin (thus a
bull equals 5s.) and a person would send for change for a thousand
pound bullock, when he would receive 200 five pound sheep. If he
wanted _very_ small change there would be a few lambs amongst them.
The inconvenience of keeping a flock of sheep at one‘s bankers’, or
paying in a short-horned heifer to one’s private account led to the
introduction of _bullion_.

As to the unhealthy custom of _sweating sovereigns_, it may be well
to recollect that Charles I., the earliest Sovereign, who was sweated
to such an extent that his immediate successor, Charles II., became
one of the lightest Sovereigns ever known in England.

Formerly every gold watch weighed so many _carats_, from which it
became usual to call a silver watch a turnip.

The Romans were in the habit of tossing their coins in the presence
of their legions, and if a piece of money went higher than the top of
their Ensign’s flag it was presumed to be “above the standard.”


“MARCH ON! MARCH ON!”

272. An army 25 miles long starts on a journey of 50 miles, just as
an orderly at the rear starts to deliver a message to the General
in front. The orderly, travelling at a uniform speed, delivers his
message and returns to the rear, arriving just as the army finishes
the journey. How many miles does the orderly travel?


“WITH A LONG, LONG PULL.”

[Illustration]

273. If eight men are engaged in a tug-o’-war, four pulling against
four, on a continuous rope, and each man is exerting a force of
100 lbs., what strain is there at the centre of the rope?


“FIND OUT.”

274. A gentleman in a train with a boy got into conversation with a
stranger, who asked him the lad’s age. The boy quickly replied, “This
gentleman, who is my uncle, is twice as old as me, but the sum of the
figures in my age are twice the sum of those in his.” What was the
age of each?


275. One of our squatters who had made his fortune in the “good
times” determined to sell his run and spend the rest of his days in
the old country. A new chum, possessing considerable wealth, and
desirous of settling down in Australia, hearing of the squatter’s
intention, interviewed him with the object of purchasing, when the
following conversation ensued:--

NEW CHUM: “How big is your run? What’s its area?”

SQUATTER: “Well, I’m blessed if I know, but I can tell you
it’s perfectly square and enclosed with posts and rails. Each of the
rails is 9 ft. long.”

NEW CHUM: “Oh, then, is it what you call a three-railed
paddock?”

SQUATTER: “Yes, that’s so, and now I remember that _the
number of rails in my run is equal to the number of acres_. If you
like you can take a horse and ride round and count the rails, then
you will know the area.” This advice the new chum acted upon.

Find out the length of his ride and the area of the run.


A Federal Problem.

It is well known to our readers that paper money--such as pound
notes--issued in one colony are depreciated in another; thus a one
pound note of N.S.W. is only worth 19s. 6d. in Victoria, and _vice
versa_. Some time ago a rather ’cute individual in Wodonga, on the
Victorian side of the border, bought a drink in a local hotel with a
Victorian note, and received in change a N.S.W. note, which was worth
then and there only 19s. 6d.; he thereupon crossed the Murray to
Albury on the New South Wales side, bought another drink for sixpence
with his N.S.W. note, and received a Victorian note equal to 19s.
6d. in change. He travelled backwards and forwards during the day,
getting his twentieth and last drink in Albury, on the N.S.W. side,
whereupon he returns to Wodonga with a Victorian pound note still to
his credit. He thus paid for all his drinks, which amounted to ten
shillings. Who lost the money?

We cannot advise readers to “go thou and do likewise,” for the simple
reason that such a proceeding would now be impossible, as exchange is
no longer charged in the two towns mentioned. It is not until we get
further from the border that the levy is made.


Doing Two Things at Once.

An inspector was examining a school in a country district some
distance from a railway station. He was afraid of losing his train,
so hurrying with his work he tried to do two things at once. Standing
in the doorway, he gave out dictation to Class III. in the main room,
and at the same time gave out a sum to Class IV. in an adjoining
room, jerking out a few words alternately.

The sum was “If a couple of fat ducks cost 19s., how many can he get
for £72 10s. 9d.” The dictation for Class III. began “Now as a lion
prowling about in search, &c.” Of course the poor children heard
both, and got a bit mixed. One little girl’s dictation began “Now a
couple of ducks prowling about in search of a lion who had lost 19s.,
&c.” While a Class IV. lad was scratching his head over the following
sum “If 72 couples of fat lions cost 19s., how much prowling could be
got for £72 10s. 9d.”


TWO CALENDAR CATCHES.

Ask a person if Christmas Day and New Year’s Day come in the same
year. The answer generally given is “Of course not, Christmas comes
in this year, and New Year’s Day in the next.”

Another question that often puzzles many. Have we had more Christmas
days than Good Fridays? The usual answer is “No, both the same.”

276. A brass memorial tablet in honour of the late Sir Charles Lilley
has been fixed in the centre of the eastern wall of the Brisbane
Grammar School Hall. The enthusiasm displayed by Sir Charles in
the cause of education generally, and his work on behalf of the
Grammar School, make this commemoration particularly appropriate.
The following is the inscription, to translate which should prove a
capital exercise to all Latin scholars. The tablet measures 50 inches
by 30 inches.

[Illustration: MEMORIAL TABLET TO THE LATE SIR CHARLES LILLEY]

It may be added that the lettering of the plate was designed by Mr.
R. S. Dods, architect, and the engraving was done in Brisbane by
Messrs. Randle Bros., the well-known engravers, of Elizabeth Street.


A Puzzle in Book-keeping.

277. A firm appointed an agent to do business on their account, and
gave him £32 17s. in cash for expenses, &c., and also supplied him
with a stock of goods, the value wholesale being £57 14s.; while in a
distant town he bought a job lot of goods for £59 19s., which he paid
cash for out of what he had realised on his first stock. He still
continued to sell, but very soon after the firm called him in, and
desired him to close his account and hand in a full statement.

His total retail sales amounted to £102 17s., and he returned goods
to the value of £31 17s., his expenses had been £25.

Question--What does the firm owe the agent, or the agent owe the firm?

THE AGENT’S STATEMENT BEING--

  Cash              £32 17
  Goods              57 14
  Paid for Goods     59 19
  Cash Sales        102 17
  Goods Returned     31 17
  Expenses           25  0

This puzzle first appeared in “HOW TO BECOME QUICK AT
FIGURES,” the answer being withheld. It is a record of
transactions that actually occurred in America, which were the
subject of litigation. Although we received thousands of replies,
not more than 5 per cent. were correct. It is a question that
individuals not conversant with book-keeping would be as likely to
solve correctly as the expert. For the convenience of those who are
unacquainted with American money we have been obliged to substitute
£ s. d., and would advise our readers to attempt a solution before
referring to the answer.

 Suppose a man and woman to marry, the man to have
       had a son by a former marriage (the gentleman who
       leaves the money); also the woman has a daughter
       by a former marriage. This son and daughter get
       married, and have a son. This is the scheme of

  My friends,--I have spare blankets, and I shall need no more;
  The tenth man can have my bed, and I’ll sleep on the floor.
  In room marked A two men were placed; the third was lodged in B;
  The fourth to C was then assigned, the fifth retired to D;
  In E the sixth he tucked away, in F the seventh man,
  The eighth and ninth in G and H, and then to A he ran
  (Wherein the host, as I have said, had laid two travellers by);
  Then taking one--the tenth and last--he lodged him safe in I:
  Nine spare rooms--a room for each--were made to serve for ten.
  And this it is that puzzles me and many wiser men.

(93) The difficulty is to determine what would have been
       the will of the testator had he foreseen that his
       wife would be delivered of twins. As he desired that
       in case his wife brought forth a son he should have
       ⅔ of his property, and the mother ⅓, it follows
       that his intention was to give his son a sum double
       to that of the mother; and as he desired in the
       other case that if she brought forth a daughter the
       mother should have ⅔ and the daughter ⅓, there
       is reason to conclude that he intended the share
       of the mother to be double that of the daughter;
       consequently, to unite these two conditions, the
       heritage must be divided in such a manner that the
       son may have twice as much as the mother, and the
       mother twice as much as the daughter. Thus we get--

          Son’s     share,  £4000
          Mother’s    "     £2000
          Daughter’s  "     £1000

       Sometimes the following difficulty is proposed in regard
       to this problem:--In case the mother should have
       two sons and one daughter, in what manner must
       the property be divided then? We refer you to the
       lawyers.

    To explain this often causes much confusion. We
       must take a simple illustration: I have a garden
       containing 10 appletrees, all bearing fruit. Now,
       there are more trees than any tree has apples on
       it; there must be at least 2 trees having the same
       number of apples--for instance, if No. 1 tree has
       1 apple, No. 2 has 2, and so on to No. 9; when we
       come to No. 10 tree, it must have the same as one
       of the other trees, as it could not have 10 or more

       This is one of those _impossible_ questions that
       one often hears. The fractions, when added together,

       The locomotive pushes No. 1 truck up to the points,
       then returns to the opposite siding and pushes No. 2
       up to No. 1 at the points; the two trucks are then
       pulled by the locomotive down the siding and pushed
       on to the main line to a position anywhere between
       the two sidings; No. 1 is then uncoupled and left
       standing, whilst the locomotive pulls No. 2 along
       the main line in order to push it up to the points
       where it is left; the locomotive returns to No. 1,
       and pulling it a short distance, in order to get
       on the proper siding, pushes it into its required
       position, uncouples, and proceeds up the other
       siding to the points to pull No. 2 into its proper

       eq. (50 plus 2_x_) miles, and is the total distance
       the Orderly travels.

    Now Orderly rides from A to D, while General marches
       from B to D, and Orderly returns from D to C, while
       General marches from D to E, and Orderly and Army
       travel at a uniform rate.

      Translation: The foundation stone of this
        building was laid in 1880 by Sir Charles Lilley,
        for many years Chief Justice, and formerly a
        distinguished member of the Government of this
        colony. He was prominent amongst those who worked
        for the first establishment of this school, and
        afterwards, by his generous gifts and by his wise
        counsel as a trustee, contributed greatly to its
        advancement. The trustees have, therefore, erected
        this tablet to perpetuate his memory here. A.D. 1898.
