be excellent for fattening cattle and is one of the best 

 foods for milch, cows. The pushing northward of the 

 corn-belt has therefore directly affected agriculture in the 

 Prairie Provinces. The story of the northward advance 

 of the corn-belt seems to warrant the belief that eventually 

 vast tracts of land in northern Canada which have not yet 

 been plowed, will one day be made to raise early-ripening 

 varieties of wheat such as those which Dr. Saunders is 

 now perfecting.®' 



XVII. The Yield of Marquis in Western Canada 



In the greater part of Saskatchewan, on summer fallow, 

 one is safe in saying that the yield of Marquis over Eed 

 Fife is at least 20 per cent. The situation in Central and 

 IsTorthem Manitoba is about the same as in Saskatchewan. 

 In Alberta the climatic conditions are more complex than 

 in Saskatchewan and Manitoba, so that for that province it 

 is difficult to make exact statements of the yield of Marquis 

 compared with that of other varieties. 



On stubhle land Marquis often appears to be no better 

 than, or about the same as, Eed Fife, provided that the 



69 In Manitoba, the chief variety of com now grown is 'North- 

 western Dent, the next variety in importance being Minnesota No. 

 13. The cobs ripen in this Province only in exceptional seasons. In 

 1914, when the mean shade temperature for July was 70° F., the cobs 

 of certain Flint varieties (Quebec No. 28 and Free Press) ripened 

 well, while the cobs of the Dent varieties ripened only partially. 

 There are about 100 silos in Manitoba. Information supplied by 

 Mr. Allan Campbell at the Brandon Experimental Farm. 



'Northwestern Dent is a variety of Red Dent corn that is not re- 

 lated in any way to either Minnesota No. 13 or Minnesota No. 23. 

 It has been grown to a considerable extent in the two Dakotas, 

 Montana, and Minnesota, and to some extent in northern Michigan 

 and Wisconsin. There is no authentic history of this variety, and 

 no one appears to know where or how it originated. Information 

 supplied by Professor Andrew Boss of the University of Minnesota.
