Comments on the table-—The most notable feature of this 
table, as compared with the table of yields for Geneva on page 
90, is ihe smaller difference in vield between sprayed and un. 
sprayed rows. This is due to the fact that in the experiment at 
Geneva late blight and rot wrought considerable havoc among the 
uusprayed plants, while in the experiment at Riverhead there was 
no attack of late blight. At Riverhead the increased yield of the 
Sprayed rows was chiefly due to better protection against flea 
beetles and to the stimulating effect of bordeaux on the foliage. 
There was no disease to combat in this experiment except, per- 
haps, a small amount of early blight. 
In section C, row 8, sprayed three times, yielded at the rate of 
20 bushels per acre more than row 7, sprayed seven times. In 
section 1}, row 12, unsprayed, yielded eight bushels per acre more 
than row 11, sprayed three times. These are plainly inconsisten- 
cies which we are unable to explain. Possibly they are due to 
errors in weighing, but we think not. Great care was exercised
