the purpose in view and Lo keep up 

 a sustained yield. This may mean 

 that more trees must be left Ihan 

 under the present system with a 

 slight increase in present logging ex- 

 penses but a large decrease the ex- 

 pense in future operations. In chang- 

 ing over from an unregulated to a 

 regulated forest the expenses for log- 

 ging will be larger for the first felling 

 but thereafter should gradually de- 

 crease as the stand of merchantable 

 timber increases. 



We also want to utilize every pos- 

 sible tree. At present we have a 

 large amount of hardwood which is 

 left in the woods and as I have said 

 before hinders the growth of the 

 coniferous trees. It is quite possible 

 to use this ior pulp with the soda or 

 sulphate processes but I understand 

 that it cannot be utilized with the 

 sulphite process. I visited a mill in 

 Austria which used beech entirely 

 and made a good quality of pulp. 

 There is, it seems to me, no reason 

 why hardwood should not be used 

 for ground wood; the fibre is, of 

 course, shorter, but it ought to make 

 a good filler. The objections are 

 that it is difficult to float and some 

 difTiculty might be encountered in 

 barking it. The first difficulty can

be overcome by spring cutting and 

 he second might be overcome by 

 peeling in the woods as is done with 

 poplar. This would lengthen the 

 time over which our supply of spruce 

 and balsam w^ould last and add much 

 to the value of our timber limits. 

 The Laurentide Company in co- 

 operation with the Forest^ Products 

 Laboratories hopes to try some ex- 

 periments along these lines this winter. 



31,000 Cords Wasted. 



Then there is the elimination of 

 logging wastes which are at present 

 larger than they should be. The 

 lumber companies usually take logs 

 from a tree until a diameter of six 

 inches is reached but the pulp com- 

 panies take down to four inches. 

 However, a very bad custom still 

 holds .of using logs thirteen and one 

 half feet long and as it is often im- 

 possible to get a log that length out 

 of a tree top much good wood is 

 wasted. We have measured up over 

 two thousand tops and we find that 

 in the St. Maurice Valley about 31,- 

 000 cords of wood are wasted each
