There are several different results to
be obtained by pruning fruit trees,
namely:
/. To keep the tree within bounds,
80 that the work Of spraying and of
picking the fruit can be done with the
greatest fa :ility.
2. To rellove dead or interfering
branches.
3. To open the top of the tree to ad.
nit air and sunshine, and to reduce
the struggle for existence among the
branches.
4. To thin the fruit and stimulate
the development of fruit buds.
5. To make the tree stocky and
increase its vigor.
There are differences Of opinion as
TO the best ways of pruning to secure
the results desired, but most success
full growers admit that regular prun-
ing is desirable. Each grower in prun-
ing his trees has in mind the securing
Of some definite objects, though he
may not know ;ust what the principles
of pruning are. Zach tree furnishes
problem in u self, but If the prin.
ciples are understood these problems
can be solved.
Avoid Bad crotches.
After tree is planted it is headed
back to single unbranched stem OF

ing on the size and age Of the tree
The second season several of these
stubs or new branches are selected to
form the scaffold limbs of the tree
Care should be taken to have these
three or four spread out we'll along
the main stem SO as to avoid bad
crotches later. The branches selected
are headed back 10 or IL inches. The
third season two or three branches are
allowed to remain on each of these
scaffold limbs, and all others cut off.
The branches selected this time should
be located so as to balance evenly and
keep open the top of the tree. The
fourth season the operation is repeat.

sons growth. In all later prunings
care should be used to save fruit spurs
and keep the bearing wood low and
well distributed throughout the tree
In pruning, all cuts should be made
close to the parent branch, leaving nc
stubs which might later decay back
and injure the tree. All wounds of
more than an inch in diameter should
be painted.
The correct principle seems to be t.
do the least cutting possible and yet
get the results desired. A great deal
of the cutting done in winter may be
avoided by little judicious pinching
back Of buds during the summer, This
pinching back prevents the growth of
branches that must be removed later
and permits better growth in the
branches that are desired.
Thinning.
The purpose of thinning is to reduce
the quantity Of fruit which tree sets
to quantity that it can mature and
ut the same time develop fruit buds for
the next years crop. An excessive
crop usually means small and often
poorly colored fruit, and the overload.
Ing frequently breaks down the limbs
of the tree. The development of seeds

fruits; thus thinning relieves the tree

winter apples it is quite likely that

Summer varieties of apples require
