where applied with bordeaux than where applied dry by means 
of a powder gun. Still there were not enough bugs on the un- 
sprayed rows to warrant a second application of poison. Flea 
beetles were quite plentiful and, as usual, injured the unsprayed 
rows more than the sprayed. Late blight appeared about August 
25. It spread slowly. From the time of the first spraying on, the 
foliage of the sprayed rows was better than that of the unsprayed 
rows. Toward the close of the season the difference became quite 
marked. At the time of digging the test rows, September 27, 
there had been no frost and many of the sprayed plants still retained 
much of their foliage while the unsprayed plants in both tests were 
dead. 
The items of expense for spraying six acres of potatoes twice 
were as follows:

The total cost of spraying was $4.02 per acre or $2.01 per acre 
for each application which is a little more than twice the average 
cost in the other twelve experiments. The method of spraying 
employed in this experiment is expensive because it requires so 
much man labor. Of course the spraying can be done very thor- 
oughly but it is doubtful if the gain is proportional to the extra 
expense. We are confident that, in most cases, horse sprayers with 
stationary nozzles will give larger net profit. On steep hillsides, 
such as were encountered in this experiment, it may be possible 
to spray by this method where a sprayer with stationary nozzles 
could not be used. 
Both sets of test rows were dug by hand September 27 with the 
following results: 
* This does not include paris green used before spraying was commenced. 
*TIncludes four hours consumed in damming brook and getting things 
ready; also four hours going after sprayer and returning it. 
* Includes four hours consumed in going after sprayer and returning it.
