The few data given in Table XII are not very conclusive. The 

 Sixty-Day variety apparently has decidedly outyielded the Kherson, 

 but the difference is due to an unexplained wide variation in yields 

 in 1906. The best midseason white varieties, Myrick Banner and 

 Lincoln, have yielded sUghtly less than the Sixty-Day. Typical pani- 

 cles and spikelets of three leading midseason white varieties of oats 

 are shown in figure 5.

In a letter dated December 20, 1917, Prof. A. C. Arny, agronomist 

 of the Minnesota station, states that in an experiment with heavy, 

 medium, and light seed in which Ligowo and Sixty-Day (Minn. No. 

 261) were used, the Sixty-Day consistently outyielded the Ligowo- in 

 an cases in 1914, 1915, and 1916, but that the yields were reversed 

 in 1917. He further states that the Victory oat has been the leading 

 variety at the Minnesota station in recent years, and that a selection
