The group of soft winter wheats includes numerous 
varieties grown extensively in the famous wheat 
districts’ of California, Oregon, Washington, and 
northern Idaho. The main varieties are Red Russian 
and Palouse Blue Stem, in Washington and Idaho; 
Red Chaff and Foise in Oregon, and Defiance, Little 
Club, Sonora, and White Australian in California. 
These are all soft, white, and rather poor in gluten. 
It is believed that under given climatic, soil, and cul- 
tural conditions, all wheat varieties will approach 
one type, distinctive of the conditions in question, 
and that the California wheat type is a result of pre- 
vailing unchangeable conditions. More research is 
needed, however, before definite principles can be laid 
down concerning the formation of distinctive wheat 
types in the various dry-farm sections. Under any 
condition, a change of seed, keeping improvement 
always in view, should be beneficial. 
Jardine has reminded the dry-farmers of the United 
States that before the production of wheat on the 
dry-farms can reach its full possibilities under any 
acreage, sufficient quantities must be grown of a few 
varieties to affect the large markets. This is espe- 
cially important in the intermountain country where 
no uniformity exists, but the warning should be 
heeded also by the Pacific coast and Great Plains 
wheat areas. As soon as the best varieties are found
