Winter wheat was a total failure at the Garden City station every 
year from 1909 to 1918, inclusive. During these years no method 
of tillage overcame the unfavorable conditions. As no cultivated 
land borders on the station, pests, such as rabbits, grasshoppers, and 
birds, often reduce the yields as much as and sometimes more than 
unfavorable climatic conditions. Green manuring has never pro- 
duced profitable yields. Early fall plowing, late fall plowing, and 
summer tillage produced profitable yields in 1915, while subsoiling 
yielded a profit in 1914. Disked corn and potato ground and listing 
were profitable in 1914 and 1915. No method has averaged a profit 
for the seven years. The average losses per acre range from $1.94 on 
disked corn and potato ground to $10.32 from green manuring. 
DALHART FIELD STATION. 
The soil at Dalhart, Tex., is a sandy loam. In some respects it 
behaves like sand. In other respects it exhibits the characteristics 
of a heavy clay soil. Its water-holding capacity is comparatively 
limited. The crops appear, however, to be able to utilize its water 
to the depth of a normal root development. 
At the Dalhart station the crop of winter wheat was totally de- 
stroyed by hail in 1910 and 1912, and these years are not used in the 
averages. In 1909, 1911, 1913, and 1916 no yields were produced 
from any of the methods. In 1914 all the methods, except summer 
tillage, produced profitable yields, but that is the only year when
