Wood light, strong, hard,- rather coarse-grained, compact ; bands of small summer cells not broad, very resinous, 

 conspicuous, resin passages few, not large; medullary rays numerous, obscure; color, light red, the sap-wood pale 

 yellow or nearly white ; specific gravity, 0.5206 ; ash, 0.26 ; largely manufactured into coarse lumber. 



Abietine, a volatile carbo-hydrogen possessing powerful anaesthetic properties, is probably obtained by distilling 

 the resinous exudation of this species, and not of P. Sabiniana ( Waifs Diet. Chemistry, 2d Suppl. 1. Am. Jour. Pharm.
