Forest Products of Canada, ipop: Pulp Wood. By H. R. 

 MacMillan. Bulletin 12, Forestry Branch. Ottawa, Canada. 

 1910. Pp. 9. 



From this compactly written bulletin we quote the following 

 figures which refer to domestic wood manufactured into pulp in 

 Canada. 



Reports were received from 25 mills in Quebec, ten in On- 

 tario, seven in New Brunswick, six in Nova Scotia and two in 

 British Columbia. The latter are new mills not yet running on 

 full time. Some ten other Canadian mills failed to report. These 

 fifty mills used 622,129 cords of wood and produced approxi- 

 mately 445,408 tons of pulp. The average value of the wood per 

 cord was $4.07 in Nova Scotia, $4.69 in New Brunswick, $5.72 

 in Ontario, and $5.83 in Quebec. In Ontario and Quebec, where 

 most of the wood was consumed, the price varied very little from 

 that of 1908. 



Of this pulpwood, Quebec manufactured 51.4 per cent., On- 

 tario 30.1 per cent.. New Brunswick 14.2 per cent., and Nova 

 Scotia 4.1 per cent. The consumption by species was: spruce 

 82.9 per cent., balsam 16.1 per cent, (a much higher percentage 

 than in 1908), and negligible quantities of poplar and hemlock. 

 The average prices per cord were: balsam $6.26, poplar $5.81, 

 spruce $5.41, hemlock $4.51. These prices, however, do not rep- 

 resent the relative value of the different species for pulp manu- 

 facture, as they are not the purchase price in all cases ; in cases 

 where the manufacturing companies own timber limits they indi- 

 cate only the cost of logging and transportation to the mill. Only 

 one pulpmill in Canada manufactures sawmill waste. 



Three reduction processes are used in Canada. Three-fifths 

 (60.8 per cent.) of the pulpwood was reduced mechanically, over 

 one-third (37.2 per cent.) by the sulphite process, and the re- 

 mainder by the soda process. In Quebec and Nova Scotia the 

 mechanical process is largely used ; New Brunswick uses the sul- 

 phite process mostly, while Ontario manufactures about an equal 

 amount of pulpwood by both processes. The soda process is 

 little used in Canada on account of the cost, though it can be suc- 

 cessfully used with a greater variety of woods than the other pro- 

 cesses. Of the wood used for mechanical pulp, spruce formed 

 nearly four-fifths (79.3 per cent.), the remainder being balsani;
