Darling states that the sprayed rows lived about four weeks longer 
than’ the unsprayed. The contrast was very marked. 
THE SPENCERPORT EXPERIMENT. 
This experiment was made by F. E. Gott, Spencerport, Monroe 
county. Mr. Gott conducted a similar experiment for the Station 
in 1904. In 1905 the experiment field contained fourteen acres 
planted with three different varieties. Owing to washing out and 
rotting of the “seed” in several places the crop on about four 
acres was practically worthless. In spraying it was necessary to 
drive the sprayer over nearly the whole of the fourteen acres, but 
in going across the bare areas the spray was shut off. This makes 
it difficult to determine accurately the expense of the spraying. Mr. 
Gott is of the opinion that the total expense, $24.40, should be con- 
sidered as being the result of spraying ten acres three times. ‘This 
would make the total expense per acre $2.44 or 81 cents per acre 
for each application. ‘The items are as follows:

The spraying outfit was the same one used in the 1904 experi- 
ment; namely, a home-made, two-horse rig spraying three rows at 
a time with one nozzle per row.1® Two men are required to operate 
it— one to pump and one to drive. The dates of spraying were 
August 7, 23, 25 and September 6. 
Three rows 664 feet long and of the variety White Giant were 
left unsprayed. 
Before spraying was commenced one application of paris green 
was made, wherever needed, over the whole field including the un- 
sprayed rows. Further than this no poison was required either on 
the sprayed or the unsprayed rows. 
As late as September 1 there was no difference between the 
sprayed and unsprayed rows, but by September 15 there was a
