DRY-LAND CROPS 



Spring Wheat Zone. 



The Hard Spring Wheat Zone takes in 

 North and South Dakota and a portion 

 of northwestern Nebraska. Of the com- 

 mon varieties the two best known are 

 Blue-stem and Red Fife. The famous 

 wheats known as "No. 1 Hard" and 

 "No. 1 Northern" which usually com- 

 mand the highest price on the markets of 

 the world have been developed from 

 these two varieties. The growing of 

 winter wheat is not possible in this zone 

 owing to the long severe winters, light 

 rains in the fall, and severe freezing and 

 thawing in the early spring. But this 

 section may also be spoken of as the 

 home of the durum wheats in America; 

 and as they seem destined to become the 

 leading spring varieties throughout the 

 whole semi-arid West, a short accoimt 

 of their origin may not be out of place.
