EXPERIMENTS WITH KHERSON AND SIXTY-DAY OATS. 
53 
growing districts are the Great Basin, the Snake River Basin, the 
Columbia Basin, and the central valleys of California. These include 
parts of the States of Utah, Nevada, California, Idaho, Oregon, and 
Washington. 
Varietal experiments with the Kherson and the Sixty-Day and 
other varieties of oats have been conducted at the following stations: 
Nephi, Utah; Aberdeen, Idaho; Burns and Moro, Oreg. ; and Chico, 
Calif. At each of these points, except Chico, the work has been con- 
ducted cooperatively by the United States Department of Agricul- 
ture and the respective State agricultural experiment station. At 
Chico the work has been conducted in cooperation with the Office of 
Foreign Seed and Plant Introduction of the Bureau of Plant Industry. 
The experiments at Pullman and Puyallup, Wash., were conducted 
and reported independently by the Washington Agricultural Experi- 
ment Station. The results of cereal experiments at the Oregon 
Agricultural Experiment Station at Corvallis have never been pub- 
lished. 
The climate of these basins and valleys, except that of Puget 
Sound, is exceedingly dry, varying from semiarid to arid. Table 
XLI contains a record of the altitude, annual and seasonal precipita- 
tion, mean temperatures for June, July, and August, and the general 
soil type at each of the seven stations in this section. 
As a rule, the precipitation of these sections is markedly low, and 
most of it occurs during the autumn, winter, and spring months. 
This is the reverse of the conditions in the Great Plains area, where 
the greater portion of the precipitation occurs during the summer 
months, the growing season. For this reason winter rather than 
spring grains are grown in this section.
