The Gray Pine is the Scrub Pine of northern latitudes. In 

 good soil it makes a fair tree, but in barren soils one finds 

 miles and miles of scrub. The leaf is bluish green covered 

 with so marked a gray bloom that the foliage rnass is posi-

 yellow, more conspicuous than those of the White Pine, not 

 so large as those of the Red Pine, and for the few days they 

 are in bloom the tree is noticeable. Cones are small, twisted, 

 and look not fully developed for they do not open evenly. 

 They are Hght gray ; sometimes they shine almost silvery 

 out of the grayish mass of foliage.
