Imports of soda pulp, and of book paper, of which it is an important con- 
stituent, from both Canada and Europe are negligible. The United States 
exports offset imports in all forms by about one-fifth. The general trend of 
requirements and of the relative amounts of the raw materials secured from 
domestic and foreign sources is shown in Figure 8 and Table 16.

Fig. 8.— The United States is more independent of foreign sources for soda pulp than for any other kind. 
Eighty per cent o Ithe pulp wood required is secured from American fo] s 
SULPHATE PULF. 
About 1,220,000 cords of wood, or 14 per cent of the requirements of 1922 for 
all paper, went into sulphate pulp. The use of sulphate pulp in the United 
States began as recently as 1904, and the first domestic production was four years 
later.

Via. 9. .Sulphate pulp was first used in the United States about 1904, and production in this country 
' pulp-wood requirements are now more than a million cords, 68 per cent 
of which comes from other countries. 
The imports of pulp wood for sulphate pulp are very small, amounting to 
lees than 2,000 cords in 1922. Imports of wrapping paper arc also small, 
aggregating in 1922 a little less than 33,000 tons, half from Sweden and the 
remainder from a number of countries. With small amounts of Null pulp 
wood and paper, it follows that imports must eonsist largely of wood pulp. 
Pulp, in fa<t, aggregated in 1922 more than 330,000 tons (Table 31) out of a
