they do not shell out and may be allowed to get 

 fully ripe in the field so they may be harvested 

 with combined harvesters and threshers, or 

 headed and taken at once to the threshing ma- 

 chine. In the northern portion of the mountain 

 region the Fife and Blue Stem, known as North- 

 ern Hard wheats are the best milling sorts. For 

 the southern half of this region wheats of the 

 Defiance type or White Touse are the leading 

 varieties. For dry farming the most successful 

 and valuable spring wheat is the Kubanka type 

 of Durum wheat. For feeding purposes, the 

 Macaroni, Polish, and Egyptian wheats are val- 

 uable drouth resistant kinds. As yet there is 

 only one variety of winter wheat which can be 

 recommended for general planting. This is 

 Turkey Ked, which is a fine milling wheat, and 

 succeeds under both systems of dry farming and 

 irrigation. Karkof winter wheat is being tried 

 and so far all reports are most favorable. The 

 Silver King, which is a beardless winter wheat, 

 has succeeded fairly well in some sections of the 

 West. 



PLANTING Seed wheat should be plump, heavy, true to 



type, clean, free from weed seeds or other grain, 

 and treated for smut. (See Chap. 18.) The 

 average amount of seed to use per acre on irri- 

 gated farms is about seventy pounds. Of the 

 larger standard kinds, like Macaroni or Polish 

 wheat, ninety to one hundred pounds may be
