cause of hail. In 1913 and 1914 crops were produced under nearly 

 normal conditions, although in 1914 the dry weather in July reduced 

 the yields somewhat. The only year in the period when the late 

 o9.ts outyielded the early ones was 1915, when the rainfall for the 

 growing season was 2 mches above normal and the yields obtained 

 were the highest recorded at the station.

1 Crop destroyed by hail in 1912. 



2 Made second growth during rainy weather in August; not ripe when the fixst frost came. 



In 1908, 1909, 1910, and 1913 the varieties were grown m unrepli- 

 cated tenth-acre plats and in 1911 and 1912 in unrephcated twentieth- 

 acre plats. In 1914 and 1915 they were grown in fiftieth-acre 

 plats replicated five times. 



LEADING VARIETIES. 



The varieties of oats that have been grown at Moccasin may be 

 divided into three groups according to their date of maturity — 

 early, midseason, and late. The early oats have given the best 

 average results. 



Data on average dates of headmg and of maturity, height, weight 

 per bushel, and yield of grain and of straw for some of the leading
