quis outyielded Velvet Chaff, on thie average throughout 

 the spring-wheat region, by from 1. 4 to 2, or more exactly 

 by 1.8 bushels per acre. 



The superior productiveness of Marquis entails in- 

 creased farm values of the wheat crop. A recognition of 

 this fact, no doubt, has been largely responsible for the 

 rapid rise of the new variety into favor with farmers dur- 

 ing the past four years, and for the corresponding diminu- 

 tion in the cultivation of Velvet Chaff, Bluestem, and Fife. 



In concluding this Section, we may compare the rela- 

 tive yields of Marquis and Fife in the United States and 

 Canada. It will be remembered that it was found in long- 

 period tests that Marquis outyielded Eed Fife : at Indian 

 Head in Saskatchewan by almost 40 per cent, and at 

 Brandon in Manitoba by over 20 per cent.*^ A calcula- 

 tion made from the Table shows that, as an average for 

 three years, Marquis outyielded Fife : in South Dakota by 

 41 per cent., in !N"orth Dakota by 29 per cent., in Montana 

 by 24 per cent., and in Minnesota by 13 per cent. It thus 

 becomes obvious that the advantage of replacing Eed Fife 

 by Marquis is nearly equal in the two countries. 



XIX. The Favorable Grading of Marquis 



As a rule, but especially in unfavorable seasons, the 

 increased yield of Marquis over Red Fife on summer 

 fallow is associated with a higher weight per measured 

 bushel and a greater plumpness of kernel. Consequently 

 Marquis tends to obtain a higher grade than Eed Fife. 

 This often results in a considerable difference in price 

 apart from the difference in yield. If, for instance, Eed 

 Fife were to produce 20 bushels to the acre grading No. 4 

 and Marquis 25 bushels grading 'No. 2, the difference in 

 value would be greater than 25 per cent, in favor of Mar-
