DISCOVERY OF MARQIHS WHEAT 249 



Marquis. Let us find out, therefore, what the masses of 

 wheat just distributed among the various varieties would 

 have been, had thej been actually yielded in 1917 by the 

 varieties to which they have been assigned (vide Table). 



The difference between the totals just given is 3,540,718 

 bushels. We thus see that if, in 1917, the 26,663,900 

 bushels of Marquis had been replaced by wheat from the 

 various varieties in the proportions in which they were 

 grown in 1914, the Minnesota wheat crop of 1917 would 

 have been reduced by 3,540,718 bushels. Instead of its 

 being 57,965,000 bushels, it would have been 54,424,282 

 bushels. 



Summing up the results of the foregoing calculation, we 

 may say that the increase in the raising of Marquis wheat 

 in Minnesota in the last three seasons has resulted in a 

 gain in the 1917 crop of 3,541,000 bushels. Taking two 

 dollars per bushel as the average price, we are justified 

 in concluding that the introduction of Ma(rquis iclieat into 

 Minnesota brought about a gain in wealth in 1917 of up" 

 wards of 7,000,000 dollars. 



By making use of the appropriate crop statistics,^^ and 

 by employing the method of investigation just explained, 

 gains corresponding to that just found for Minnesota, can 

 be found for the two Dakotas. 



So far as Montana is concerned, the statistics for the 

 relative contributions of the different wheat varieties to 

 the total crop of 1914 are not available. However, we 

 know that Montana in 1917 produced 17,963,000 bushels 

 of wheat, of which 45 per cent, or 8,083,000 bushels was 

 Marquis; and we also know that the estimated yields of 

 the spring-wheat varieties in bushels per acre in 1917 were 

 as follows: Marquis 9.3, Velvet Chaff 7.5, Bluestem 6.5, 

 Durum 9, and Fife 7.5. ^^ This allows us to conclude 



26 and 27 Loo. mt.
