 PINUS L. 



P. Strobus L. White Pine. 



Reported from a few counties in the southern, and a few in the 

 northern, part of the State, also found in various hill regions through 

 the central counties. The tree in this State does not reach its full 

 development, and is much less valuable than farther north. Its 

 scant distribution gives it no local value, although it is the most 

 common and valuable buildiDg material of the northern States, and 

 is used for an almost infinite variety of other purposes. 



P. divaricata (Ait) Sudw. Gray or Northern Scrub Pine. 

 (P. Banksiana Lamb.) 

 In the central and northern part of the State, occurring in scant 

 numbers. A small tree from thirty to sixty feet high and rarely 

 exceeding two and one-half feet in diameter. Too local to be of 

 economic value. 



Lake (Hill); Putnam (MacDougal). 



41-Geol.
