The Red Pine occasionally attains the height 

 of 80 or 100 ft. with broad irregular pyramidal 

 head and dark green foliage tufted in thick 

 needles at the ends of its rough branchlets. 

 It is an upland tree, being found on dry sandy 

 soil and is distinctly northern in its distribu- 

 tion. Never forming e.xclusive tracts of forest 

 of any size, it is scattered in open groves 

 where conditions favor its development, and 

 many of the slopes and ridges which overlook 

 the lakes of the Adirondacks and New England 

 are beautified by the presence of this tree. 

 Its straight columnar trunks, rarely over 2 

 or 3 ft. in diameter, are vested in a reddish 

 brown bark (hence the name) fissured into 

 broad irregular plates and ridges which flake 

 oft' in irregular scales. 



The wood is moderately heavy and hard and 

 is valued for the spars of vessels, piles, sills, 

 and lumber for genera! construction purposes. 

 A cubic foot of the dry wood weighs 30.2.5 Ibs.i 

 The bark is occasionally used for tanning pur- 

 poses.
