6 STUDIES OF TREES 



mental tree, the white pine is an excellent tree to plant 

 on abandoned farms and for woodlands and windbreaks 

 throughout the New England States, New York, Pennsyl- 

 vania, and the Lake States. 



Commercial value: The wood is easily worked, light, 

 durable, and will not warp. It is used for naval con- 

 struction, lumber, shingles, laths, interior finish, wooden 

 ware, etc. 



Other characters : The fruit is a cone, four to six inches 

 long. 



Comparisons: The tree is apt to be confused with the 

 Bhotan pine (Pinus excelsa), which is commonly grown as 

 an ornamental tree. The Bhotan pine, however, has needles 

 uch longer and more drooping in appearance. 



THE PITCH PINE (Pirns rigida) 



Distinguishing characters : Here there are three needles 

 to each cluster, Fig. 4. They are dark, yellowish-green 

 needles about four inches long. The rough-looking branches 

 of the tree may be seen studded with cones throughout the 

 year, and clusters cf leaves may be seen sprouting directly 

 from the trunk of the tree; see Fig. 5. The last two are 

 very characteristic and will distinguish the tree at a glance. 



Form and size: It is a low tree of uncertain habit 

 and extremely rough looking at every stage of its life. 

 It is constantly full of dead branches and old cones which 

 persist on the tree throughout the year. 



Range: Eastern United . States. 



Soil and location: Grows in the poorest and sandiest 

 soils where few other trees will grow. In New Jersey 

 and on Long Island where it is native, it proves so hardy
