CANADIAN FORESTRY ASSOCIATION 37 



This forest cover would not only give the settler the fuel and building material 

 he would need, but it would powerfully aid in maintaining the water powers with 

 which a provident hand has so liberally endowed our favoured Province. Indus- 

 tries dependent on cheap motive power would be assured, agriculture would be 

 enormously benefited, our settler would be free from any possible wood famine, 

 and nothing but good could result from the adoption of the policy I have but briefly 

 outlined. 



The suggestion I have made, may, I trust, find sympathisers amongst those 



' here to-day and I earnestly hope that this Association, in its wisdom, will take the 



necessary steps to draw the different Provincial Governments' attention to the 



reform I have attempted to advocate. Its adoption cannot be prejudicial to the 



country; it can only be a practical factor for good. 



The PRESIDENT. I think that this is the first paper which has been read to-day 

 which is based upon practical experience. Anything that has had thirty years 

 trial, as Mr. Joly de Lotbinidre says his experiment has had, must be worth con- 

 tinuing, and I think his concluding words of value, when he expressed the hope that 

 this Association would bring pressure on the Provincial Governments to induce them 

 to make an effort to put into force some such scheme as that which has been so 

 successfully worked on the Seigniory of Lotbiniere. 



I will now call upon Mr. A. H. D. Ross, of the Faculty of Forestry in Toronto 

 University, to read his paper. 



FOREST SURVEY METHODS. 

 A. H. D. Ross, M.A., M.F., FACULTY OF FORESTRY, UNIVERSITY OF TORONTO. 



Mr. President, Ladies and Gentlemen, When I was asked to prepare a paper 

 for this meeting of the Canadian Forestry Association, it seemed to me that the 

 members might be interested in a brief description of a few of the methods employed 

 by forest engineers to "take stock," at it were, of various kinds of forest properties. 

 Accordingly the title I have chosen for my paper is "Forest Survey Methods." 



DEFINITION. 



A complete Forest Survey includes, (1), A more or less accurate plane and 

 topographic survey of the tract under examination; (2), A careful estimate of the 

 amount of timber upon it; (3), A determination of the rate at which the timber 

 is growing; and (4), A study of the conditions of light, moisture, soil and other 

 factors which influence both the present and the future condition of the forest crop. 



DEGREE OF ACCURACY REQUIRED. 



The accuracy of the methods employed to bring together information of this 

 sort will, of necessity, be determined by (1), The use that is to be made of it; and 

 (2), The time and money allowed for the collection of the necessary data. For 

 example, if a woodsman is given a month to look over a township, and is required
