IIO REPORT OF THE BOTANICAL DEPARTMENT OF THE 
There was no rot, even on the unsprayed rows. ‘The yield of 
small potatoes was at the rate of 19.7 bu. per acre on the sprayed » 
rows and 17 bu. per acre on the utisprayed. 
West test. The rows were 962 ft. long by 3 ft. wide, 15.1 rows 
being required to make an acre. The yields were as follows: 
Two sprayed rows (second one on each side), 1,768 lbs. marketable tubers. 
Middle two unsprayed rows, 1,052 Ibs. marketable tubers. 
Yield, sprayed, 222 bu. 28 lbs. marketable tubers per acre. 
Yield, unsprayed, 132 bu. 23 lbs. marketable tubers per acre. 
Gain, 90 bu. 5 lbs. marketable tubers per acre. 
There was no loss from rot either on the sprayed or the un- 
sprayed rows. The yield of small potatoes was at the rate of 8.4 
bu. per acre on the sprayed rows and 9.2 bu. per acre on the un- 
sprayed. 
By combining the results obtained in the two tests, the average 
gain in this experiment is found to be 80 bu. 51 Ibs. per acre. At 
the time of digging the east test the market price of potatoes in 
Bridgehampton was 60 cents per bushel, but when the west test 
was dug it had dropped to 55 cents. In computing the value of 
the gain an average price of 5714 cents per bushel has been used 
which makes it $46.49. After deducting $9.62, the expense of 
spraying, there remains a net profit of $36.87 per acre. 
Although the profit in this experiment was remarkably large, the 
experiment is believed to have been a perfectly fair one in all 
respects.
