Excerpt: ...year being 33.1 per cent of the total, while that of the Lake states constituted 23.5 per rent, that of New York 22.7 per cent, and that of Pennsylvania 8.5 per cent. SODA PROCESS. The bulk of the poplar has always been reduced by the soda process, and in 1908, 56.4 per cent of the total quantity of wood so reducedwas poplar. Pine supplied 12.7 per cent, and the miscellaneous woods 26.8 per cent. Because of the adaptability of the soda process to so many different woods, its use is widely distributed. Pennsylvania produced 28.4 per cent of the soda pulp; New England, 25.3 per cent; New York, 10.7 per cent; and "all other states," 35.6 per cent. The wood used in the Lake states is almost entirely hemlock and spruce, and thus far none of the mills operating there have reported the manufacture of pulp by the soda process. USE OF SAWMILL WASTE. An interesting result of the efforts of the pulp manufacturers to secure cheaper raw material is tlje increasing use of sawmill waste instead of cord wood and larger sized timber. Table 4 summarizes the reports upon this subject in 1908. Altogether over 250,000 cords of slab wood and other mill waste were used, at an average cost of $4.26 per cord, only about half the average cost of pulp cord wood. The bulk of mill waste was slab wood obtained from sawmills, though small quantities of sawdust, shavings, etc., were also reported. Spruce and hemlock supplied most of this material, while the remainder was chiefly pine. There is undoubtedly a large field for the development of methods which will profitably utilize mill waste in the production of pulp, and as the price of timber increases much progress may be expected in this direction.
