 peculiar that 



the best spruce stands are found, not in the north, but in the 

 Appalachian Alountains, those in West Virginia taking the 

 palm. The average stand in Maine is about 3000 or 4000 

 feet to the acre, and the best stands seldom exceed 15,000

Spruces generally grow mixed with hardwoods or other conifers, in this case with balsam fir which has formed a 

 thick under-story. The fir is a less valuable tree than the spruces but is increasing in amount because it grows 

 faster than the spruces and takes its place in the forest when the wood is cut.

 similar in char-

 it is exceed-

 tell them apart. 

 Nor is it gen- 

 erally impor-

 of the plainest and most homogeneous of our woods. 

 Consequently it has no place as a cabinet or orna- 

 mental wood. 



Commercial Uses of Red Spruce 



SPRUCE was little used till the supply of pine began 

 to decrease, when its better grades came into the 

 market as a substitute for the pine. ^Vlthough it 

 now has an assured place of its own as a lumber wood 

 and even has substitutes, chiefly balsam fir, it has never 

 been pre-eminently noted as a lumber producer — not be- 



cause of any lack of value and adaptability, but because 

 it is of more value for something else — wood pulp, sev- 

 enty per cent of the cut being used for this purpose. 

 The spruces are the leading pulpwoods of the world 

 and red spruce the leading pulpwood of the United 

 States. .About 70 per cent of the pulpwood used in
