The test rows (Twentieth Century) yielded as follows: 
Average of two sprayed rows, 203 lbs.=122.3 bu. per acre. 
Middle unsprayed row, 225 lbs.==135.5 bu. per acre. 
Loss, 13.2 bu. per acre. 
Believing that there had been no late blight Mr. Hayt was sur- 
prised to find many rotten tubers — 33.7 bu. per acre on the sprayed 
rows and 39.1 bu. on the unsprayed. Probably, there was a light 
attack of late blight late in the season. Perhaps a couple of ad- 
ditional sprayings would have prevented this and made the spray- 
ing profitable. Why the unsprayed rows outyielded the sprayed 
ones is not known. It can scarcely have been due to the spraying. 
With potatoes at 80 cents per bushel and the expense of spraying 
$2.32 per acre the apparent loss was $12.88 per acre. 
THE JAMESPORT EXPERIMENT. 
Conducted by Henry A. Hallock, Jamesport, Long Island, seven- 
teen acres of potatoes (in two lots) were sprayed five times. The 
sprayer used was a one-horse, four-row “ Hudson”’ sprayer carry- 
ing two nozzles per row. The dates of spraying were July 1, 13, 
25, 31 and August 7. The water used in preparing the bordeaux 
was pumped with a gasoline engine and hauled from 10 to 8o rods. 
In the first two sprayings paris green was used with the bordeaux. 
The four check rows in each lot were treated with paris green 
twice — July 1 and 13. The unsprayed rows died two weeks earlier 
than the sprayed ones owing to the ravages of flea beetles which 
had been much lessened by spraying. There was no blight or rot.
