 three times that for softwood saw timber. Similarly, in total volumes,

the hardwood ratio is about two times. This is consistent with the 

 generally known fact that depletion is proceeding more rapidly in the 

 hardwoods than in the softwoods, and that the problem of adequate 

 hardwood supplies is more acute. 



In annual drain (in cubic feet) for all classes of timber (table 11 and 

 fig. 12) the forests of the East account for three times as much as 

 those of the West; more than half of the volume of the eastern cut is 

 from hardwoods, while that from western hardwoods is insignificant. 

 The large excess of the South over the Pacific coast consists principally 

 of hardwood saw timber and cordwood trees. Total southern dram is
