Seventeen rows 29014 feet long were marked out three feet 
apart. Immediately before planting the furrows were opened with 
a plow. Commercial fertilizer at the rate of 500 pounds per acre 
(ten pounds per row) was scattered in the furrows by hand. 
The soil was fine and in excellent condition for planting which 
was done May 26. The seed pieces were placed 15 inches apart 
in the row and covered about 4 inches deep by means of hoes. 
The seed was of the variety Rural New Yorker No. 2 selected 
from the sprayed rows in the experiment of 1905. On May 21 
the seed tubers were given the formalin treatment for scab. The 
following day they were cut into pieces of hen’s egg size in 
such manner that each piece contained at least one good eye. 
During the season the plants were harrowed twice, cultivated 
three times and hoed once. Up to about August 15 the weather 
conditions were favorable but after that date the potato crop was 
considerably injured by heat and lack of rain. 
At Riverhead.— The land used at Riverhead was a level plat of 
sandy loam on the farm of H. HH.” Hallock. The soil was of 
about the same character as that used for the experiment in 1905. 
The previous crop was potatoes. A mixture composed of 1500 
pounds of commercial fertilizer (4-10-5 formula) and 500 pounds 
flowers of sulphur (for scab) was applied to the land at the rate 
of 2000 pounds per acre by means of a fertilizer drill which 
opened a furrow about two inches deep. Furrows for planting 
were made by deepening the drill furrows with a shovel plow. 
The seed potatoes were of the variety Green Mountain and 
came from an unsprayed field in which there was considerable 
rot. After the formalin treatment for scab the seed tubers were 
cut and dusted with sulphur. The seed pieces were planted 
April 26, 15 inches apart in the row, at the rate of 20 bushels 
per acre, and covered by means of a horse hoe. The experiment 
included 15 rows 290% feet long. ° 
Cultivation was sufficiently thorough to keep the field entirely 
free from weeds throughout the season. 
PREPARATION AND APPLICATION OF THE BORDEAUX MIXTURE. 
Both at Geneva and Riverhead the bordeaux mixture used 
was made by the 1-to-8 formula, approximately, and applied very 
thoroughly as in former years. At Geneva, the first spraying of 
Series I and the first two sprayings of Series II were made with 
a barrel spray dump, all others with a knapsack. At Riverhead 
all of the spraying was done with a knapsack.
