be kept stocked with the choicest hardy
fruit trees and the land will support
also certain vege tables. and some farm
crops, But trials viii be made in nd.

native wild flowers. A. part of the

WHY PRUNING rs NECEss MRY.
Many people object to regular
tree pruning, ON the ground
that il robs thees Of strong
and healthy limbs, and lis at
variance with natures methods: but
In the forest, trees undergo natural
pruning due to crow6ing, whereas. in
our orchards and among trees Guilt
waited for shade or ornament plants
are placed at distances which prevent
this natural pruning The increased
amount of food available to plants
under artificial conditions frequently
excites growth. so that the distance
becomes too great between the different
NhorlS of branches. which naturally
develop from near the end of the
growth of each season and gives the
plant an open form and the appearance
Of having been built by stories. BY
n Judiclous use OF the pruning knife the
agrdensr shortels his annual growth.
thus reducing the distance between the
branches formed In successive wears
The tree has then more compact and
symmetrical form is better suited to
serve the purpose OF am orchard or
ornamental tree Moreover some of
our most desirable ornamental trees
and shrubs have an unfortunate nat ural

each of which grows at about the same
rate. with q very narrow angle between

es increase In size the union between
them not being perfect, severe pressure
placed upon one of them has a tendency
to split them apart,
OTHER OBJECTS OF PRUNING.
Fruit trees should be pruned Ca) 10
check future growth and so insure The
production of larger or better fruit by
reducing It's quantity; Cb) to acceler-
ate future growth, as when weak muir
sery stock Is cut back In order TO con-
centrate the power of growth in one
compact and smaller stem; (c) TO re-
Jnyenate old trees, as when apple or
sha do trees are cut back In order to
induce a growth OF new branches cd
10 control plant diseases, as when in
the case of pear blight, the affected
branches are cut of and burned This
disease may be carried from tree to
tree by bees, which visit the fruting
spurs that appear on the young trunks.
Through the blossoms the disease
gains an entrance To the main body of
the tree and destroys It, but N the dis
ease enters only by blossoms borne at
the ends of the bra inches. these can
be cut Off, II the disease appears. and
the trees saved Ii follows that all
fTuiting spurs should be removed from
The body and main frame work OF pear
trees
In the case az plum and peach rot,
the disease can be stayed hy the re-
inovaI OF branches which interfere and
