average yield of tlie Marquis exceeds that of the Kubanka by about 

 15 per cent, and that of the best Preston by more than 18 per cent. 

 It much excels the Bluestem varieties and nearly doubles the yield of 

 the Glyndon Fife. 



RESULTS AT ST. PAUL, MINN. 



The experiments recorded in Table VI were conducted independ- 

 ently by the IMinnesota Agricultural Experiment Station, and the 

 results are presented here through the courtesy of the director and 

 other officers. 



Table VI shows that in the two years when data on winter wheat 

 are available, the Turkey variety outyielded all the leading varieties of 

 spring wheat. In the 3-year average yield, the Marquis slightly out- 

 yields all other varieties of spring wheat. The quantities by which it 

 exceeds the Preston and Glyndon, however, are too small to be 

 significant, amounting to 2.5 and 4 per cent, respectively. The 

 advantage of the Marquis over the Haynes and Kubanka is about 15 

 per cent in- each case. The 2-year average yield of the Turkey is 

 about 35 per cent higher than that of the Marquis. 



In correspondence. Profs. Andrew Boss and A. C. Arny state that 

 these varieties were grown on small duplicated plats, 3 by 132 feet, 

 with cultivated 2-foot alleys on either side. The yields, therefore, are 

 higher than those obtained on larger plats and in fields, but are com- 

 parable one with another.
