New YorK AGRICULTURAL EXPERIMENT STATION. 103 
There was no rot. The yield of small potatoes was at the rate 
of 16.7 bushels per acre for the sprayed rows and 24.8 bushels 
per acre for the unsprayed. 
Test No. 3— The rows were 374 ft. long by 32 in. wide, 43.66 
rows being required to make anacre. The yields were as follows: 
Second sprayed row on the south, 167 lbs. marketable tubers. 
Second sprayed row on the north, 182 Ibs. marketable tubers. 
Middle unsprayed row, 54 lbs. marketable tubers. 
Yield, sprayed, 126 bu. 58 lbs. marketable tubers per acre. 
Yield, unsprayed, 39-bu. 18 lbs. marketable tubers per acre. 
Gain, 87 bu. 40 Ibs. marketable tubers per acre. 
There was no rot. The yield of small potatoes was at the rate 
of 16 bushels per acre for the sprayed rows and 25.5 bushels per 
acre for the unsprayed. 
By combining the results of the three tests the average gain 
is found to be 75 bu. 39 lbs. marketable tubers per acre. Spray- 
ing increased the yield 134 per ct. At 40 cents per bushel, the 
market price at time of digging the test rows, the gain would have 
a value of $30. 26. After deducting $4.24, the expense of spraying, 
there remains a net profit of $26.02 per acre. 
THE WOODBURY EXPERIMENT. 
This experiment was conducted by A. and F. Van Sise, Wood- 
bury, Long Island. It included two fields of potatoes, one of 
3.75 acres and another of 5 acres. ‘The potatoes were of the 
variety Green Mountain. Both fields were sprayed with bor- 
deaux mixture three times — June II, 25 and July 14. The spray- 
ing outfit used was a home-made one consisting of a Spramotor 
hand pump mounted in a 50-gallon barrel on a two-wheeled, one- 
horse cart. The eight nozzles (two for each of four rows) were 
catried on a Spramotor telescoping-pipe attachment at the rear 
of the cart. One man did both the pumping and the driving. 
Another man assisted with the preparation of the bordeaux mix- 
ture. The water required for making the bordeaux was obtained 
from a pond adjoining the smaller field but about sixty rods 
from the larger one. About 85 gallons of bordeaux mixture per 
acre were applied in each spraying. 
Four unsprayed rows were left in each field. ‘These were 
kept free from “bugs” by two applications of paris green in 
water made on June 11 and 25. On the same dates paris green
