As soon as the fires are started, the canes should be syringed
with tepid water twice a day until the buds burst, and then all
syringing of the vines should cease until they have fully ex-
panded their first leaf. The temperature on starting should be
between 40° and 45° at night, rising to 55° or 60° during the
day. As soon as the buds are burst the heat may be increased
at night to 45° or 50°, and so gradually increase the night heat
a little, so that by the time the first leaves are wholly expanded
the night temperature may be as high as 50°, running up in the
day to 10° or 15° higher. The atmosphere should be kept suf-
ficiently moist by placing metallic trays, containing water, on the
pipes, and by sprinkling the border and paths, but never by
syringing’ the pipes when they are hot. This year, the lateral
shoots that start from the growing wood should be pinched at
one leaf from the main cane, and those from last year’s wood
stopped at the fifth joiht, and all the fruit taken off except one
bunch, or, at most, two, if they are small. When the leading
cane has reached two-thirds of the length of the rafter it may be
stopped, and when it starts again, stopped once more, after it has
made two more joints, repeating this process until growth ceases.
The laterals, must also be stopped every time they start, after
making one joint more beyond the last stop. Air should be given
more and more freely as the season advances, so that the wood
