The White Pine (pinus Strobus)




Distinguishing characters: The tree can be told at close range by the

number of needles to each cluster, Fig. 2. There are *five* needles

to each cluster of the white pine. They are bluish green, slender,

and about four inches in length.



At a distance the tree may be told by the *right angles* which the

branches form with the main trunk, Fig. 3. No other pine shows this

character.



Form and size: A tall tree, the stateliest of the evergreens.



Range: Eastern North America.



Soil and location: Prefers a deep, sandy soil, but will grow in almost

any soil.



Enemies: Sucking insects forming white downy patches on the bark and

twigs, the _white pine weevil_, a boring insect, and the _white pine

blister rust_, a fungus, are among its principal enemies.






Value for planting: Aside from its value as an ornamental 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, Pennsylvania, and the Lake States.



Commercial value: The wood is easily worked, light, durable, and will

not warp. It is used for naval construction, 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 much longer and more drooping

in appearance.
