310 REpoRT OF THE HorTICULTURAL DEPARTMENT OF THE 
TRE SDER AEA RSs 
Wood ashes were applied to the four treated plats at the rate 
of 100 pounds per tree annually, with the exception of two 
years, 1901 and 1902, when the applications were omitted. As 
there are 48 trees per acre, 4,800 pounds were applied per acre. 
The ashes were thoroughly mixed, weighed separately for each 
tree, and applied broadcast to a line midway between adjacent 
rows. Applications were made in the spring and were well 
worked into the ground. No other fertilizer was applied to 
any part of the orchard during the first five years of the ex- 
periment; cover crops were plowed under as follows: 
1893—Oats and peas 
1894—Crop not stated 
1895—Crop not stated 
1896—Sweet clover 
1897—-Mammoth clover 
1898—Crimson clover
