Several conditions and causes are responsible for the great 
difference in yield between the different plots.. The potato 
beetles became numerous and were working badly on all the 
plots when the first application of Paris green was made, July 
7. Where the Bordeaux and Paris green were used together, 
the beetles disappeared in a day or two. Where the Paris 
green was used alone, but few of the beetles were killed. By 
the time it was evident that the poison alone was not going to 
destroy the beetles, much of the foliage from plots 1 and 2 had 
been damaged quite seriously. As soon as the weather would 
permit, a second application of Paris green was given, the 
poison being used this time, at the rate of 1 pound of Paris 
green to 80 gallons of water. Even this did not destroy all 
the beetles, so the old fashioned way of ‘‘ bugging’’ with a pan 
and stick was resorted to at the same time that the third appli- 
cation of Bordeaux was given to plot 4. Plot 1 was so badly 
damaged that it never fully recovered its foliage. Plot 2 re- 
covered its foliage and kept green till within about two weeks 
of the time when plot 4’s foliage died. The black flea beetle 
worked badly on the unsprayed potatoes at different times 
through the season. Fungi did not show seriously on any of 
the foliage, but early blight was present, and probably more 
or less late blight, though neither worked rapidly enough to 
cause noticeable damage. None of the potatoes showed signs 
of blight rot when dug, nor afterwards in the cellar. 
CAN DISCOLORED POTATOES BE PREVENTED FROM ROTTING 
AFTER DIGGING? 
A quantity of potatoes from the 1904 crop that showed dis- — 
colored spots but that were not spoiled for immediate use were 
taken from the field at the time of digging, washed, and placed 
in crates for treatment to determine whether they could be pre- 
vented from rotting. Part of these were thoroughly sprinkled 
with dry, air-slacked lime, and part of them were left un- 
treated. 7 
On January 11 these potatoes were examined. The discol- 
ored spots on both the treated and untreated were sunken and 
black, and the diseased areas were considerably enlarged. No 
soft rot had appeared, and nearly every potato had one or more 
apparently Healthy sprouted eyes. It is hardly probable that -
