HOW UNITED STATES CAN MEET PULP-WOOD REQUIREMENTS. 17 
total dependence of 376,000 tons (Table 18). This is the only grade of wood 
pulp in which we are more dependent on Europe than on Canada. European 
countries, chiefly Sweden, Finland, Norway, and Germany, furnished in 1922 an 
equivalent of 35 per cent of our requirements in pulp wood. American forests 
furnished 41 per cent, and Canada 28 per cent. 5 (Table 17.) Exports were small. 
Our relative dependence upon foreign countries in 1922 for sulphate imports 
in pulp form was as follows: Canada, 46 per cent; Sweden, 42 per cent; Finland, 
8 per cent. Only these countries made shipments of importance. 
A complete shutting off of pulp-v/ood imports would therefore affect only 
about 2,000 cords of wood used for sulphate pulp, on the basis of 1922 data. 
The general trend of requirements and the relative amounts of raw material 
from domestic and foreign sources are further shown in Figure 9 and Table 18.

the chemical process. Wood requirements for sulphite have increased nearly 
five times since 1899, and by more than 3| million cords. (Table 19.) 
Native forests supplied only 48 per cent of the pulp wood needed for sulphite 
in 1922. This is in striking contrast with 1899, when these forests furnished 75 
per cent. Our largest imports are from Canada, which in 1922 shipped as 
pulp wood, pulp, and paper the equivalent of more than 1| million cords of 
pulp wood, approximately one-third of total requirements and 63 per cent of 
imports. Exports were small. 
Unlike either soda or sulphate, a large volume of the sulphite pulp consumed 
is imported in paper. Approximately 1,030,000 tons of newsprint paper, con-
