JACK PINE 
Jack pine is hardy and rapid growing. It will grow on poor soil, 
but requires plenty of light. The wood is light, moderately strong, 
coarse grained, and suitable for rough construction and for posts 
when treated with a preservative material. 
The jack pine will grow well even on south slopes where there is 
little moisture and where many other trees have failed. (Fig. 6.) 
From the standpoint of utility it is not the most desirable tree, but 
its ability to grow on poor soil makes it valuable. Because of its 
shallow-root system, it may die out during the periods of extreme 
drought in open stands where grass is abundant. Overcrowding 
also will cause the weaker trees to die. It can not be recommended 
for heavy loam or clay soils. 
WESTERN YELLOW PINE 
Western yellow pine is one of the hardiest of the trees that can 
be grown in this region. It will do well on ridges and north slopes

or in the pockets, and responds to cultivation with increased growth. 
It thrives best in pure stands (that is, unmixed with other species) 
and grows rapidly enough to establish itself within a few years. It 
is probably the most valuable tree that can be grown in this part of 
the country and should give more uniform success than any other 
species. The growth for the first few years is slow, but after the fifth 
year it may grow from 12 to 18 inches annually. The growth of this 
tree is often set back by the pine-tip moth, an insect the larvae of 
which bores through the buds and tender shoots and kills them. 
SCOTCH AND AUSTRIAN PINES 
Scotch and Austrian pines have been planted extensively in the 
eastern and central parts of the State, and they will do well in the 
western half if planted on north and east exposures. If available, 
the Riga or northern European variety of Scotch pine should be 
planted. Scotch pine planted at Halsey on a north exposure aver-
