Improving Canadian agriculture, J. W. Robertson (Com. Conserv. Canada 

 Rpt., 3 (1912), pp. SU-IO.j). — Observations are here made regarding systems of 

 agriculture in Canada and methods of improving them, as the result of a sur- 

 vey of 1,212 Canadian farms by the Commission of Conservation, appointed 

 to inquire into and report on questions relating to conservation of soil fertility, 

 agricultural labor, health, and prosperity of the country- 

 It is noted that a varying number of farms in each of the 9 Provinces in- 

 vestigated reported increases in the yield of crops as compared with 10 years 

 ago except in ^Manitoba where no farms reported an increase, but 46 out of 100 

 reported a decided decrease. The general conclusion reached by the commission 

 is that where a systematic rotation of crops prevailed there has been from two 

 to three times the profit to the farmers and a conservation of fertility.
