EXPERIMENTS WITH KHERSON AND SIXTY-DAY OATS. I 
ture during July is about 70° F. at all stations and above this point 
during August at all except a few. The mean temperature during 
June ranges from 61.9° at Orono, Me., to 78.7° at Denton, Tex., 
exceeding 70° as far north as Indiana, Illinois, and Nebraska.

RESULTS IN THE NORTH ATLANTIC STATES. 
In New England, the agricultural experiment stations of Maine 
and New Hampshire report varietal experiments with Sixty-Day and 
Kherson oats. The former station has conducted a rather extensive 
series of experiments with oats since 1910, including both commer- 
cial and pure-line strains of the Kherson variety. No recent varietal 
work has been reported by the New Hampshire station, but a limited 
number of varieties, including the Sixty-Day, were tested in 1904 
and in the 4-year period from 1906 to 1909, inclusive.
