New YorK AGRICULTURAL EXPERIMENT STATION. 229 
THE WILLINK EXPERIMENT. 
Conducted by M. J. Buntin, Willink, N. Y. Twenty acres 
of potatoes, variety Snowflake Jr., were sprayed three times 
with a two-horse E. C. Brown Co. “ Auto” sprayer carrying 
one nozzle per row and covering four rows at each passage. 
The water used in the preparation of the bordeaux was pumped 
by hand from a stream about 80 rods distant from the potato 
field. Three rows 80 rods long were left unsprayed for a 
check. So few bugs appeared that poisoning of the check 
rows was not required. AS a precautionaly measure arsenite 
of soda was used with the bordeaux in the first spraying, but 
this seems to have been quite unnecessary. 
The expense account contained the following items:

The check rows were 80 rods long by 32 in. wide. Owing 
to the weather being disagreeable at digging time the test was 
confined to a representative section 500 feet long. The yields 
were as follows: 
Average of two sprayed rows, 121 Ibs==109.8 bu. per acre. 
Middle unsprayed row, 113 lbs==102.6 bu. per acre. 
Gain, 7.2 bu. per acre. 
What caused the greater yield on the sprayed rows is not 
clear. There was no blight of any kind and only a few flea 
beetles. 
The market price of potatoes being 70 cents per bushel 7.2 
bu. have a value of $5.04. After deducting the expense of 
spraying there remains a net profit of $2.26 per acre.
