PINE FAMILY 



The Hemlock is one of the most beautiful of the cone 

 bearing" trees ; and although similar in general form to the 

 spruces, rigiditv has transformed itself into ease and formality 

 into grace and beautv. The branches are slender and pliant, 

 heavilv clothed with foliage, drooping in habit and the lower 

 sweep the ground. As the tree becomes older they become 

 large and strong and stand out horizontally. The dilference 

 between youth and age is marked. The wood is not valuable, 

 it has neither strength nor durabilitv, but the bark is e.xten- 

 sivelv used in tanning and is the chief commercial product of 

 the tree.
