New York AGRICULTURAL EXPERIMENT STATION. 71 
The yield® per acre for the sprayed plants was at the rate of 
71,000 fruits, weighing 25,265 pounds; for the unsprayed plants 
at the rate of 40,650 fruits, weighing 12,860 pounds. Hence, the 
increase in the number of fruits per acre due to spraying was 
30,450 and the increase in weight 12,405 pounds. The sprayed 
plants suffered considerably from anthracnose, but not at all from 
downy mildew. 
EXPERIMENTS IN 1898. 
INTRODUCTORY. 
During the season of 1898 codperative spraying experiments 
on late cucumbers were conducted in four different localities on 
Long Island; viz.: at Greenlawn, Deer Park, Mattituck and 
Smithtown Branch. In each case an entire field was sprayed. 
At Greenlawn the sprayed field contained one and one-half acres, 
sprayed seven times; at Deer Park, two acres, sprayed eight times; 
at Mattituck, two acres, sprayed five times; and at Smithtown 
Branch, 2.15 acres, sprayed seven times. 
THE TERMS OF COOPERATION. 
The Station bore all expense of spraying and directed how and 
when it should be done. The owners of the fields experimented 
upon performed all of the operations connected with growing, 
gathering and marketing the crop according to their own judgment 
and at their own expense, and carried out the spraying under the 
direction of a representative of the Station. 
Therefore, the Station is responsible for the spraying only, and 
does not commit itself to the recommendation of any of the cul- 
tural methods employed on these experiment fields. 
THE SPRAYING OUTFIT. 
The spraying outfit used consisted essentially of a two wheeled 
cart which carried a spray pump mounted in a 50-gallon barrel 
and fitted with two leads of hose twenty feet long. Three men 

6 These yields are not comparable with the yields in the preceding experi- 
ment because the fruits were allowed to attain greater size.
