New York AGRICULTURAL EXPERIMENT STATION. 257 
THE INTERLAKEN EXPERIMENT, 
monauccedeby P.)C.-and 22°B. Bradley, Interlaken;-N.'Y., who 
sprayed 8% acres of potatoes (in two lots) four times — July 13, 
24, August 7 and 23. The sprayer used was a two-horse, four-row 
‘Watson ”’ sprayer carrying one nozzle per row in the first and last 
sprayings and two nozzles per row in the second and third sprayings. 
The bordeaux used was of the 4-4-50 formula. In the first two 
sprayings paris green was added at the rate of one-half pound to 50 
gallons. Water was obtained from a stream 25 rods distant. Three 
check rows were left in each lot. In the east lot the checks were 
864 feet long by three feet wide; in the west lot, 726 feet long by 
three feet wide. The checks received paris green twice, July 13 and 
24. Atno time during the season was there any contrast in appear- 
ance between sprayed and unsprayed rows in either lot. There 
was no blight, no rot and no damage done by bugs. Flea beetles 
caused some damage and there was much tip burn.
