HABITS Of Trees.

HABITS Of Trses.
William J.. Hall. OF the Bureau o!
reatry, United States Department
Asricu,ture, writes thus Of the
bits OF trees:
free CUmpanlonship,-ln almost
cry region certain kinds Of trees
e found together. This is due to u
nllori,y of preferences in regard to !
I, heat, moisture ard light. Two !
ses adapted to the same conditions
u thrive best In the same situation
10 White Ash and Black Walnut are
cd examples. Having similar pref
ences, they have almost Identical
nges and are very generally associ'
ed. There Is also another reason
by trees accompany one another
tree may so influence its surround
IS as 70 make them favorable to an
her tree where otherwise they would
unfayorable. AS an example OF
ch influence, The Chestnut on sterile
ndy plains In portions Of New Eng
nd forms a much.branched tree
hlch shades the ground and keeps II
DIST and cool. Such conditions are
vorsb.e TO the termination OF the
'hite Pine in that region; consequent
II Is found coming up abundantly
snea'h the Chestnut. but not so abun'
antly on the open, unprotected
round.
Eject Of Change in surroundings
change in the surroundings OF
rec always modifies its habit OF
rowth II The change Is toward more
avorable surroundings the result Is
cen in increased yigor, rate Of growth
nd size; II toward unlavorable sur
oundtngs. the reverse will be true
he stately Tulip.tree of the central
EASTERN states Is said TO be mere
hrub In Florida. The reason Is that
b ere II Is out OF its range Of adapta'
ion. The White Elm, which grows
With tall ard vase.likc form In New
England, in the semiarid parts OF Kan
as and Oklahoma is low and spread
ng liEc an apple tree. Nor is form
he only variable character. On the
western elm the leaves are fewer IN
iumbcr, smaller, thicker, and mucl
oughc. than on the New England tree
n oih.r parts of the tree there are
ilfferDa. OF the same Kind, thous.
hey are 10, so noticeable as those
n The form and foliage These vara
ions have resulted from the differ
snces u SOL and climatic conditions
% Will D.. tree has been subjected
Gradu.t Change The difference II
form l.'w,.n two trees Of the SAINT
kind 30 Different localities has COM
about through gradual divergence o
chaia.,g.i....s. To a certain dcgre,
chances .. this kind can be brough
about iu practice. When a gradua
chauc made in the surroundings o
a tree corresponding change take
place In the tree itself Thus II stoc
OF the New England elm he slowi
moved Sc ward through many ger
era,,ous. S, viii gradually change 4
form and other characteristics TO b
like the western tree; and II must b
assumed hat this change is necc'
sary TO enable 1t to live under 1t
new conditions.
Sudden Changes Sudden change
IN the surroundings OF tree frequen
Ii cause IS death, because It can NJ
anickly change itself to meet the r.
ouircments OF its new conditions. tn
New England elm moved at once
tho sem.arii west is likely to die, b
cause Il IS not adapted to the cond
lions Of soil, light. heat, and moistul
OF that region, In the prairie marsht
OF northern Indiana there are occ
slona, knobs which once supportC
thrifty oaks OF moisture.loying kind
Now that the marshes have bee
Drained the drying out of the soil hi
causaG the oaks to die The chani
Was too sudden, Sutdenness al
Intensity Of change often account 4
the failure Of trees TO thrive whit
moved away from the region to whit
they were adapted. This is also wi
eastern trees so often die when NOV,
10 the west. This is why nursery sto,
grown near by can be more safe
planted than that grown in a dista
region. It Is a practical matter, al
should be generally understood.
