 Sooth. Has glau- 



cous leaves, and ^^^^^^^ 

 appears to us to ' -^ 

 differ from A. (n.) 

 rubra only in the 

 colour of the cones. 



The cones are ra- 

 ther longer and red- 

 der than those of A. 

 nigra, and covered 

 xvith resin. Michaux 

 says that the red 

 spruce is in no way 

 inferior to the black 

 spruce in the quality of its timber, which " unites in the highest degree all 

 the good qualities that characterise the species." He also states that, instead 

 of being a low tree, it is superior in size to 

 the black spruce, as it generally grows in 

 richer soil ; and that the wood is reddish, 

 instead of being white. In Lawson's Manual, 

 it is stated that A. rubra differs essentially 

 both from A. nigra and A. alba in all its 

 parts ; and particularly in its leaves, which 

 are more slender and sharper-pointed than 

 in either of these species,
