throughout with the variety Green Mountain. In the latter field 
two four-row strips were left unsprayed. A part of the 21 acres 
was sprayed four times, a part three times and a part twice, the 
total amount of spraying being equal to 66% acres sprayed once. 
The spraying was done with a Spramotor hand-power pump 
mounted on the truck of a discarded Aspinwall sprayer and rigged 
to spray four rows at a time with three nozzles for each of the 
two outside rows and two nozzles for each of the two inside rows. 
The items of the expense of the spraying were as follows:

The cost per acre for each spraying was $1.36%. This high 
cost is largely due to the expense of hauling water to the field. 
Although the work was light, the team while thus employed was 
not available for any other purpose so it is necessary to charge for 
full time. 
In the eleven-acre field containing the two strips of unsprayed 
rows the plants made a luxuriant growth and seemed to be doing 
well until about the middle of July when they were seriously 
injured by drought. On July 20 Mr. Burke wrote that the crop 
had been so much injured by drought that he thought it might 
not pay to spray any more. Up to that time there seemed to be 
no benefit from the spraying. In fact Mr. Burke was of the 
opinion that the unsprayed rows were superior to the sprayed 
ones. On July 22 rain came and at the same time flea beetles 
appeared in swarms. After this rain the plants revived and another 
spraying was made early in August. [From the time of the out- 
break of flea beetles the sprayed rows made a better appearance 
than the unsprayed. Probably the increased yield on the sprayed 
rows was chiefly owing to the better protection against flea beetles. 
Early blight did not enter into the problem to any extent and late 
blight appeared only at the close of the season. bugs were kept 
well under control both on the sprayed and the unsprayed rows
