grown there with great success for many years previous to the origin 

 of this hybrid. Preston has proved to be a better variety than either 

 of its parents, both in yiekl and in range of adaptability- The region 

 in Avhich its parent varieties grow is very humid. Doctor Saunders 

 chiinis that Preston ripens its grain from three to four days earlier 

 than either of its parents. In view of this fact it is reasonable to con- 

 clude that it is better adapted to regions having diminished rainfall 

 during the latter part of the season, and experience has justified the 

 conclusion. Preston has given the best results of all the spring 

 wheats introduced into the Northwest. It is to-day grown success- 

 fully in the southern part of Canada and in a part of the United 

 States that includes North Dakota, eastern Montana, Minnesota, 

 South Dakota, and Wisconsin." 



TURKEY. 



Turkey Avheat {Triticiim vvlgare) is considered the hardiest vari- 

 ety grown at the present time in the United States. It is a bearded 

 sort, with white chaff, small head, and red grain. It is especially 

 Avell adapted to semiarid regions, as is readily seen from the region 

 in which it is grown. This variety was introduced into Kansas 

 about twenty-five years ago. For a while it was confined to a small 

 district of that State, but during the past twelve or fifteen years its 

 excellent (puility has become generally known, and consequently it 

 is grown on a much larger area. It came originally from Crimea 

 and other i)ortions of Taurida, in southern Russia. That country 

 does not differ greatlv from the section of the United States in which 

 the variety has given such good results. Though it is not a variety 

 giving unusually heavy yields, it is well adapted to resist droughts 

 and may be depended upon for a greater average yield than any other 

 variety grown in Kansas. It ripens rather early, and thus escapes 

 the excessive droughts which frequently prevail during the latter 

 part of the wheat season in that district. It is especially adapted 

 to the Great Plains region, including, roughly, Kansas, Okhthoma, 

 southern Nebraska, southern Iowa, northern Texas, and portions of 

 Missouri and Arkansas.'' 



ZIMMERMAN. 



The variety known as Zimmerman {Triticum indgarc) is grown 

 to some extent in the same region as the one just described. How- 

 ever, it has a number of essential points of difference and some char-
