Tho climate controls vegetation
in a great degree, is quito evident,
and IL is equally true that vegeta
ton itself has n marked effect up
on the climate. In the first place
II exerts an influence upon the
wind. Where the land is bare Of
trees, the wind has an unobstucted
sweep and where this prevail 3,
and is violent, the climate is not
only pleasant to man and beast but
Is uniavorable TO vegetation.
Western farmers know how this is
upon their broad unshcltered prai.
ries, AMI New Englanders know
how il is along their bleak sea
coasts. The only way to grow
handsome and healthy trees in
such localities, is first to surround
ones farm or garden with a belt
of coarse trees like willow. silver
poplar, and evergreens. Outside
of such verpant barriers, tho trees
and shrubs. IL planted grow lean,
lopsided and stunted F; inside they
stand erect, well developed and in
vigorous. Without this protection
there is unpleasantness Of having
gale forever blowing about ones
cars, the ccaseless roar Of the wind

the windows and doors, tho in

the discomfort of cattle at all sea.
sons, but especially in winter put
these and the like things together,
aud we find that whatever serves
q break the violence of the wind,
or to change its direction, is n
thing of considerable importance.
1t should not be forgotten that air
in motion produces more chillncss
than the RDme air at rest. Wet
your finger and hold it up in the
etill air, and you will hardly feel
the cold ; but swing il around, and
the hand will bo rapidly chilled.
The difference between the climate
ofa windy region and one sheltered
from driving currents of air, is
equally great.

declared that men in all climates,
by stripping tho hills of trees,
were preparing for themselves to

and want OF water. The eyapor-
alton from trees produces u cool
and moist local atmosphere. The
ovcrhanging boughs prevent the
too rapid evaporation of moisture
from the ground, and dissipation
by the wind. Tho sources ofnear-
ly ali brooks and creeks are to be
found in springs among the hills;
and by cutting oiF the trees which
have always overshadowed them,
the moisture is rapidly evaporatcd
and the springs lowered, it not
dried up.
