7. Some form of stock raising, combined with crop
growing, will furnish manure for making humus and
building up the soil. The old English adage, " No

grass, no cattle; no cattle, no manure; no manure, no
grass," is true everywhere.
Special farming, as orchard, berry, truck or garden
farming, cannot follow the rotations general farming
must practice for success and profit.
WHAT GENERAL IRRIGATION FARMING SHOULD IN-
CLUDE.
General farming under irrigation should include in
its rotation :

1. At least one money or cash crop.
2. At least one cultivated crop.
3. At least one legume crop.
4. At least one livestock or feeding crop.
5. These crops should be grouped so as to most eco-
nomically distribute farm labor throughout the year.
6. The farmer should arrange his rotation so he
shall be able to turn cheap, bulky feeds into milk, poul-
try or meat products.
7. We should, through a carefully worked out ro-
tation, practice factory methods on the farm, turning
ordinary waste products into profits. The meat
packer so utilizes the calf, lamb and pig that nothing
is now lost but the bleat and the squeal. The adop-
tion of a definite crop rotation and the practice of fac-
tory methods are tending more and more to stop the
leaks that leach away a part of the profits on far too
many farms, while it will increase the quantity and,
at the same time, improve the quality of the output of
every irrigated farm.
