although so far as bugs are concerned the experiment seems to have 
‘been a fair one. There was no rot.

The test rows gave the following yields: 
Average of two sprayed rows, 373 lbs.==286.8 bu. per acre. 
Middle unsprayed row, 197 |lbs.===151.5 bu. per acre. 
Gain due to spraying, 135.3 bu. per acre. 
The market price of potatoes being 65 cents per bushel 135.3 
bushels would have a value of $87.94. Deducting the expense of 
spraying, $5.24, there is left a net profit of $82.70 per acre. 
THE GREENWICH EXPERIMENT. 
Conducted by P. C. Billings, Greenwich, N. Y. Ten acres of po- 
tatoes were sprayed all over three times and six acres were given 
a fourth application. The sprayer was a two-horse, six-row “ New 
Model Aroostook” carrying one nozzle per row. In the first spray- 
ing 4-4—-50 bordeaux was used; in the later ones, 6-6—50 bordeaux. 
The water used was dipped from a tank filled by a windmill. It 
had to be hauled about 75 rods. Paris green was used with the 
bordeaux in three sprayings and the entire fiell was treated twice 
besides with paris green in lime water (one pound to 50 gallons). 
The three check rows, 665 x 3 feet, were treated four times with 
paris green — June 20, July 1, 13 and 23. The dates of spraying 
with bordeaux were June 29, July 10, 23 and August 14. The 
contrast between sprayed and unsprayed rows was not great, but 
toward the close of the season it was plain that the unsprayed 
plants had lost more of their lower leaves. However, both sprayed 
and unsprayed plants carried some green foliage through to frost. 
They suffered but little from insect or fungus enemies of any kind.
