232 Report OF THE BOTANICAL DEPARTMENT OF THE 
THE VICTOR EXPERIMENT. 
Conducted by C. E. Green, Victor, N. Y. Ten acres of 
potatoes were sprayed twice with a one-horse, home-made, four- 
row sprayer carrying one nozzle per row. ‘The dates of spray- 
ing were July 10 and 27. The bordeaux used was of the 
4-5-50 formula and the water used in its preparation had to 
be hauled about 150 rods. In the second spraying arsenite 
of soda was used with the bordeaux. On the same date the 
four check rows were treated with arsenite of soda in lime 
water. During the whole season there was no marked dif- 
ference between the sprayed and unsprayed rows. Some dam- 
age was done by flea beetles, but none whatever by blight. 
No rot was found at digging time. 
The expense account contained the following items:

The test rows were of the variety Sir Walter Raleigh. No 
representative of the Station was present at the digging. The 
rows were measured and the potatoes weighed by Mr. Green. 
The rows were 618 ft. long by 34 in. wide. 
The yields were as follows: 
One sprayed row, 234 lbs=97 bu. per acre. 
One check row, 189 Ibs.—=78.3 bu. per acre. 
Gain, 18.7 bu. per acre. 
The market price of potatoes at digging time being 60 cents 
per bushel the gain of 18.7 bu. had a value of $11.22. After 
deducting the expense of spraying, which is $1.93 per acre, 
there remains a net profit of $9.29 per acre.
