EARLY VARIETIES. 
The Sixty-Day and Kherson varieties are the only early oats that 
have been tested at Moccasin during the entire seven years. 1 The 
Sixty-Day variety was introduced from southwestern Russia into the 
United States by the United States Department of Agriculture in 
1901. The Kherson was imported from the same general locality a 
few years earlier by the Nebraska Agricultural Experiment Station. 
Plats of the Kherson and Sixty-Day oats at the Judith Basin sub- 
station are shown in figure 12. The two varieties are practically 
identical. The straw is rather short and fine and the heads loose 
and spreading. The grain is yellow in color, small, long, and rather 
slender. The hull is thin, and under favorable conditions the weight 
per bushel is high. In the Judith Basin these varieties usually reach 
maturity in 95 to 105 days and are about 10 days earlier than the 
midseason varieties. At Moccasin the average yield of the Sixty- 
Day is slightly larger than that of the Kherson. Two pure-line
