Taken from Dept. Bull. No. 1241 "How the United States Can Meet Its Present and Future Pulpwood 
Requirements," by Earle H. Clapp and Chas. W. Boyce. 
1 Contains no allowance for deduction in stand by spruce bud worm, which amounts to 40 per cent or 
about 27} _ million cords in Maine. 
In order to make clearer the advantages to be gained by extending 
the pulp-wood supply to other species, Tables 3 and 4 are presented. 
These show the amounts of pulp wood consumed in each process in 
the United States in 1922 and the production of paper by types, 
together with observations as to the species pulped and the pulps or 
other raw materials used in the various types of paper.

Easily ground, white, long-fibered species such as spruces and firs. 
Nonresinous long-fibered species such as spruces, firs, and hemlocks. 
Process may be applied to many of the pines and hardwoods. 
Easily pulped, easily bleached hardwoods, such as poplars, birches, 
Sulphate 
maples, beech, and gums. Process may be applied to the conifers. 
Any species of conifer. Process may be applied with advantage to hard- 
woods also.
