mated at 20 per cent. Making these correc- 

 tions, the average daily production would 

 be approximately 2,800 tons, which may 

 be estimated as equivalent to 2,800 cords. 



The soda process was first introduced 

 into this country in 1860, the first mill

being near Philadelphia. The number of 

 mills in 1899 had increased to 21 in opera- 

 tion in 9 states, having an estimated daily 

 capacity of 5 24 tons, distributed as f ol lo ws :

Estimating two cords of wood to a ton 

 of pulp, this would indicate a daily con- 

 sumption of about 1,048 cords. This esti- 

 mate is probably nearly correct. This 

 wood is largely Poplar. 



The sulphite process was invented in 

 America in 1867, but the pulp was first 

 made by it in the United States at Provi- 

 dence, R. I., in 1884. The number of 



mills in 1899 was 68, in operation in 16 

 states, having an estimated daily capacity 

 of 1849 tons, distributed as follows: 



From data at hand giving the actual 

 production of sulphite during the first half 

 of '98, this estimate of capacity appears to 

 be much too high, and should probably be 

 cut down to 1,400 tons. 



Estimating two cords to a ton of pulp, 

 this would indicate a daily consumption of 

 about 2,800 cords. 



Assembling these estimates, we are en- 

 abled to form some idea of the amount of 

 wood required for pulp-making, and as- 

 suming that the soda process requires Pop- 

 lar wood mainly, we have an annual con- 

 sumption of other kinds of wood used in 

 the mechanical and sulphite processes 

 amounting to about 1,680,000 cords 

 (counting 300 working days to the year), 

 or, allowing two cords to the thousand 

 feet, approximately 800,000,000 feet, in 

 addition to 310,000 cords, or 155,400,000 

 feet, mostly Poplar. 



From this figure, representing the con- 

 sumption of wood, to determine the annual 

 cut in the United States, there must be de- 

 ducted that which is brought from Canada, 

 the quantity of which we clo not know. 

 A very rough estimate indicates that it is 

 from 10 to 15 per cent, of the total quan- 

 tity consumed in pulp making. This 

 would bring the cut in the United States 

 down to from 860,000,000 to 810,000,000. 

 While this may seem to the uninformed a 

 large quantity, yet compared with the 

 quantity used for other purposes, it be-
