On che planting of tree you will want to pro-
coed with the greatest care. For the best results,
organize tree-planting program in your town. Ii

interest yourself in the proposition. In selecting
trees for street planting the following qualities
should be considered in about the order named:
Form hardness adaptability, rapidity of growth
shade protection, neatness and beauty If there is
any doubt on the question 1t is advisable to con-
suit the state forest commission the local forester
other authority who can tell what
rieties are best for given locality.
No general rules, of course, can be given, but in
larger part of the eastern United States it will
be found that for narrow streets the red MAPLE
red gum or ginkgo can be recommended; for wider
streets. Norway maple Eastwood. horse chestnut
or pin oak; and for wide avenues. white elm,
white oak. red oak and tulip poplar.
Qualities Needed in Street Trees.
Street trees should have hardness and adapta-
bility. They should be vigorous, be able to re-
cover from mechanical injuries and be as re-
sstant possible against insect attack and dis
1t is not desirable to have trees which cast
too much shade, particularly on narrow streets.
Houses and sidewalks need sun, in summer.
Deciduous, broadleayed trees are most satisfac-
tory. Again, the question of neatness should be
be considered and the tlees which will break up
the pavement such as silver naples. or those
which ef-the pavement with Their bloom In the
spring, such as cottonwoods and psplars should
Ue avoided. Black locust should not be planted
because it is likely to be destroyed by the borel
worm Beech is slow grower and casts too
dense shade for any street.
Trees planted along street should be of the
same kind, the same size and uniformly spaced.
On narrow streets trees planted every 40 feet
apart, and alternated opposite sides of the
street, will be found sufficiently close. On Wider
streets they should be from 40 to GO feet or even
farther apart. the distance being determined partly
by the size which the tree is likely to attain and
by other habits.
Every tree should have at least six square feet
Of earth above its roots. 1t is more important that
there be plenty of space where the pavement and
roadway are paved with concrete than If brick or
other loose onted materials are used.
Keep the Roots Moist.
In planting tree, move many of the roots ms
possible cloudy day is better for transplanting
tree than bright, sunny one because a bright
sun quickly eXhauss the stored-up moisture An
important point is in regard to packing the earth
around the roots. They should have close contact
with the ground. To do this, fill in around the
roots with finely pulverized earth, working IT
under and around the roots by hand and compact
ing it. the earth is wetted down rs 1t is put in II
will make much better contact
Many trees which are unsuited for one reason or
another for sidewalk are most attractive and
ornamental in park or on lawn. The beech for
instance, which has no value for street planting.
