534 Forestry Quarterly 



Mr. T. Adams, of London, England, an expert of international 

 repute. 



Inventories of Canadian forests are still being compiled for 

 British Columbia and Saskatchewan. Much has been done dur- 

 ing the past year to lessen the number of forest fires along rail- 

 way lines. With but few exceptions, the Commission has had 

 the hearty support of the railways in this work. As a result, 

 great forest areas undoubtedly have been saved from the ravages 

 of fire. These and other phases of Canadian forestry questions 

 are considered in the report by such well-known authorities as 

 Dr. B. E. Fernow, Messrs. R. H. Campbell, H. R. MacMillan, 

 G. C. Piche, and A. D. MacTier. 



The agricultural surveys and illustration farms operated for 

 some years by the Commission have proved of such value that 

 the Federal Department of Agriculture has recently taken over 

 the work and is largely extending it. 



Canada's mineral resources are considered at length by Dr. 

 F. D. Adams, Dr. E. Haanel and Mr. W. J. Dick. In connection 

 with waterpowers, especially as applying to boundary waters, 

 interesting and valuable papers by Messrs. A. V. White and 

 L. G. Denis, are included in the report. 



The report is splendidly illustrated, and a carefully prepared 

 index makes it of unusual value for reference purposes.

Preservative Treatment of Timber. By H. F. Wqiss and C. H. 

 Teesdale. Advance copy of paper presented at meeting of the 

 International Engineering Congress, in San Francisco, Cal., Sep- 

 tember 20-35, 1915. Pp. 45. 



This paper presents a general review of the results obtained 

 in the United States in the artificial preservation of cross-ties, 

 piling, bridge timbers, mine timbers, poles, posts, and paving 

 blocks. The most valuable portion is the long table in which 234 

 of the most reliable durability records on timber located in the 

 United States have been included. This represents a vast amount 

 of painstaking compilation, and will prove of great practical 

 value. 



"The oldest records reported to the authors on the efficiency of 

 preservative treatment are on the full-cell creosote, Burnett, and
