FOREST TREES. 39 
not otherwise protected, should have screens planted 
near them. Experience has shown that sheltered 
orchards, other things being equal, are the most 
productive; besides, their fruit is less likely to be 
shaken from the trees by violent winds. 
Cattle should be carefully debarred all access to 
evergreens, as they are fond of amusing themselves 
by twisting and breaking the branches with their 
horns. In making forest plantations on the plains 
towards the Rocky Mountains, the propriety of 
previously planting screens of Cottonwood and White 
Willow for their protection has been suggested. It 
seems quite likely that this may be found expedient, 
if not necessary. ‘These trees, particularly the 
Cottonwood, are more hardy when young than many 
of the more valuable kinds of timber, and may answer 
a good purpose in sheltering them from the scorching 
winds which, in Summer, sweep over those regions. 
Both are easily grown from cuttings, which should 
be set as early in the Spring as practicable. The 
Cottonwood is found on the banks of streams every- 
where throughout the West, and is therefore easily 
obtained. : 
The best method of managing tree plantations on 
the Western plains is, however, yet to be learned by 
experience. The practicability of raising timber in 
that region can scarcely be doubted, since it seems 
certain that where grass will grow treesmay be made 
to grow also.
