IRRIGATING TREES 

 Sergl. B. M. Slitt, Canadian For- 

 estry Corps, France, formerly Chiel 

 Fire Ranger under the Dominion 

 Forestry Branch at Pas, Manitoba, 

 in a recent letter to the Branch says: 

 We are still hard at work over here 

 doing our best to supply the growing 

 needs of the front line trenches. We 

 have been cutting white poplar this 

 last two months, most of it going into

About one-third of the total acre- 

 age in the valley we are now working 

 is under reforestation and it is highly 

 interesting to note the growth and 

 system of planting the young trees. 

 We have cut some 5 ft. and over at 

 the stump. Most of the trees are 

 planted along creeks and between 

 every row of trees a ditch is dug 

 which is kept full of water regulated 

 by small gates or w'eirs. 



Finding New Uses For Our Woods 



By Dr. John S. Bates 



Siif>erinlendent, Forest Products Laboratories of Canada. An Address Delivered Before The 



Canadian Forestry Association, Montreal, February 7th, under 



title "Forest Products in Canada." 



My first intention was to survey 

 the whole field of forest products as 

 briefly as possible. However, this 

 has already been done in a paper | 

 read before the Canadian Society 

 of Civil Engineers, reprints of which 

 are available for anyone interested. 

 It seems unnecessary to repeat this 

 detailed discussion, and I shall there- 

 fore touch on only a few points which 

 stand out in prominence before those 

 who are concerned with the welfare 

 of our forests. 



Wood Exports vs. Munitions 



We must not lose sight of the 

 significance of wood in Canada's list 

 of natural resources. Forest pro- 

 ducts are next in value to agriculture, 

 the income being something over 

 $200,000,000 annually. In studying 

 pulp and paper industry now brings 

 into the country a larger income than 

 any other manufacturing industry 

 with the exception of munitions and 

 is an outstanding example of an 

 export business yielding real money in

distinction from war business largely 

 based on domestic credits. At the 

 present time it is out of the question 

 to ship large quantities of wood pro- 

 ducts across the water and we see 

 Europe being drained of its limited 

 supply to feed the war machine. In 

 the future the Empire will turn to 

 Canada for its supplies, particularly 

 for the valuable softwoods which 

 fortunately predominate in this 

 northern climate. 



In considering the economies of 

 forest products there are certain 

 methods of utilization which are the 

 main units and which are self-con- 

 tained, such a*s lumber, pulp and 

 paper, and wood distillation. The 

 tendency has been to start with round 

 wood from the forest for each pro- 

 cess, so that control can be more 

 certain and each plant can be inde- 

 pendent. The possibilities for econ- 

 omy by co-ordinating one indiistry 

 with another are becoming more 

 apparent every day. Tlie expansion 

 of the main industries wdll bring 

 about these new methods by very- 

 reason of their size, so that there will 

 be enough wood w^aste at one centre 

 to serve as raw material for a by- 

 product plant. Already the kraft
