of settlers' slash is pointed out, with special reference to the 

 situation in Canada. There is urgent necessity for some progres- 

 sive action on the part of both Dominion and Provincial govern- 

 ments to meet the situation. The various methods of disposal are 

 discussed, mainly from the standpoint of advantages and dis- 

 advantages, and the conditions under which each is preferable. 

 The practice in this respect on the United States National forests 

 is summarized. 



An account in considerable detail of the working of the Top- 

 Lopping Law in the spruce forests of New York state is given, as 

 a result of a field trip last autumn. The future applicability in 

 Canada is considered. 



In the discussion of the question of using crude oil as fuel for 

 locomotives we note that in the United States oil is used exclus- 

 ively on 20,910 miles of railway line and partially on 4,720 miles, 

 and that already oil is in use in Canada on 587 miles of line 

 (1912). Its use in British Columbia is to be still further ex- 

 tended. A map of the United States and Canada is given, show- 

 ing the lines using oil and those using coal. There are extracts 

 from reports of the various railway companies using oil, which 

 give their experience as compared with coal. 



The remainder of the volume is given over to a brief account, 

 by various authors, of forest planting in the different provinces ; 

 and the report of the Committee on forests presented at the an- 

 nual meeting of the Commission of Conservation. Various ap- 

 pendices are added. 



The report is admirably got up, with illustrations that illus- 

 trate, and contains much useful information that heretofore was 

 not readily available in Canadian forestry literature. In future 

 reports, we would like to see not only an account of the Com- 

 mission's work in forestry, but also a chronicle of the year's de- 

 velopment in each province, including private enterprise.
