SILVICAL CHARACTERISTICS OF THE FIFTY-SIX MOST 

 IMPORTANT CANADIAN FOREST TREES. 



The data were gathered and compiled by members of the classes of 

 1913 and 1914, Faculty of Forestry, University of Toronto. The sources 

 of information were varied, including Dominion Forest Service Bulletins, 

 U.S. Forest Service Silvical Leaflets, forest planting leaflets, circulars 

 and bulletins, and the works of Sudworth, Sargent, Britton, Jepson, etc. 

 Growth figures were furnished by Mr. A. H. D. Ross, M.A., M.F. ; the 

 diameters in all cases being "breast high", that is, \\ feet above ground. 



In general the botanical sequence and nomenclature followed by 

 Sudworth in U.S. Forest Service Bulletin 17 have been adhered to. For 

 each tree the information is arranged according to the schedule below. 



For ready reference a table is appended to show relatively, by means 

 of symbols, the most important silvical characteristics of the trees. 

 Three grades are made for each silvical characteristic, and a tree's grade 

 for that characteristic is indicated by a symbol. The method of using 

 the table is explained at the end of the description of abbreviations used 

 in the table.
