northward and westward as the climate becomes too 

 severe for fall seeding. Roberts (1908, p. 147) ascer- 

 tained that " Red Texas oats tends to ' run out ' after 

 two years' growing in Kansas, giving way to a black 

 variety, the seed of which always appears in seed of the 

 red sort imported from Texas. In the latter state the 

 black-seeded plants are present, but do not supplant 

 the red sort as in Kansas."

102. Western Intermountain oat district. The inter- 

 mountain district includes scattered areas, largely irri- 

 gated, between the Sierra Nevada and the Rocky Moun- 

 tain ranges. The percentage of cultivation under dry 

 farming is rapidly increasing. The district is not so 

 well adapted for oats as for wheat and certain kinds of 

 barley. Late large-kerneled varieties, such as Swedish 

 Select, Banner, and Siberian, do best generally where there 

 is irrigation. Side oats are fairly well adapted, and occa- 

 sionally hulless oats are found. Very high yields are 

 obtained, particularly in the northern portion, and the 

 bushel weight is usually high. The Swedish Select is 

 especially well adapted for irrigation, but also does well 

 under dry farming, and is widely distributed. Kherson 

 and Sixty-Day do well on the dry farms. The total oat 

 production of the district is small. Winter oats is grown 

 to a small extent, particularly in Utah.
