25 and 26. The seed pieces were placed exactly 15 inches apart 
in the row. They were covered four inches deep by means of 
hoes. 
The seed was of the variety Rural New Yorker No. 2, selected 
from the rows sprayed every two weeks in the experiment of 
1903. On May 11 the seed tubers were given the formalin treat- 
ment for scab.° Twenty-four hours before planting they were 
cut into pieces weighing about! one ounce each (11 bushels per 
acre) without regard to the number of eyes except that each piece 
bore at least one good eye. Although much care was taken to 
reject all tubers showing signs of rot, undoubtedly an occasional 
diseased piece was planted. 
During the season the field was harrowed once (as the plants 
were coming through), hoed once and cultivated four times. 
The plants were not hilled at all. 
At Riverhead.—The previous crop was cauliflower. The land 
was plowed 6 to 8 inches deep April 20. After treatment with 
formalin for scab, planting was done by hand on May 4 with 
pieces of hen’s egg size placed 15 inches apart in the row and 
the rows three feet apart. The seed used was of the variety Car- 
man No. 1, selected from the sprayed rows in the experiment of 
1902. 
The trenches for planting were opened with a shovel plow. 
Home mixed fertilizer’ costing $25 per ton was: sown in these 
trenches by hand at the rate of 1,000 pounds per acre, or 25 pounds 
per row. Before planting, the fertilizer was mixed with the soil 
by running a cultivator through the trenches. The seed was 
covered to a depth of about four inches by means of the shovel 
plow used in opening the trenches. 
The cultivation consisted of two harrowings (one before the 
plants were visible and the other as they were breaking through), 
six cultivations with a horse cultivator (once before and five 
times after the plants were up), and one hoeing. In the last 
cultivation the plants were well ridged. On August 8, large 
weeds in the rows were pulled and three weeks later a hoe was 
used to remove the few remaining weeds in the rows so that
