EVERGREENS OF COLORADO 



25 



The cones of the Engelraann spruce are usually about one and one-half 

 inches in length and composed of red-brown scales somewhat broader and 

 more rounded than those of the blue spruce. This is one of our most 

 valuable native lumber trees in Colorado. The wood is light, soft and 

 nearly white in color and while not very strong, it is extensively manu- 

 factured into native lumber, mine timbers and is used to some extent for 

 poles, posts and fuel. The bark is sometimes used in the tanning of 

 leather. 



While this tree is not often planted for ornament, it is well adapted 

 to such use in this state and well selected specimens are nearly equal in 

 beauty to the blue spruce. It is not adapted, however, to dry situations, 

 for under such circumstances, the foliage is apt to take on a yellowish 

 color, which detracts much from its appearance. 



3. GENUS Pseudotsuga DOUGLAS FIR, DOUGLAS SPRUCE. 



The name of this genus means "false hemlock," which is taken from 

 the partial resemblance which these trees bear to the hemlocks. They 

 are nearly intermediate, however, between the true spruces and the firs. 

 They are tall, stately evergreens with much the same form as the spruces,
