the varieties, though the Winter Turf is several days later than any 
of the others. The average height of the Bicknell, Culberson, and 
Red Rustproof is about the same, 34 inches at Arlington Farm and 
35 to 38 inches at College Park. The Winter Turf is about 4 inches 
taller than the other varieties at both places. The Winter Turf has 
produced the highest yields of straw and the Bicknell the highest 
weight per bushel. The Red Rustproof has been lowest both in yield 
of straw and in weight per bushel. 
Descriptions of the more important varieties and selections are 
given in the following paragraphs. Heads of these varieties are 
shown in figure 5.

Bicknell. — The Bicknell oat, C. I. No. 206, was obtained from 
Argentina by the United States Department of Agriculture in 1902, 
through Mr. F. W. Bicknell. The panicles are small and rather dense. 
The short, buff kernels are usually very plump, so thai the weight per 
bushel is high. This variety is one of the earliest to mature, usually 
ripening about June 12 to 15. The Bicknell has yielded slightly 
more than any other variety for the six years it has been grown at 
College Park, where it has produced quite consistently high yields 
every year. At Arlington Farm the original variety has averaged 
10.2 bushels less and the best selection 4.43 bushels less in a 4-year 
test than the highest yielding variety in the test, which was a Red
