ture during July is about 70° F. at ail 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.
