the appearance of having been well whitewashed. About noon 
of the second day the weather turned colder and remained so 
for several days. During the two days that the trees were being 
sprayed the temperature varied from 30° to 40°. The weather 
was, as a rule, cloudy, with light wind the first day and heavy 
wind the second. 
The spray was applied in this orchard as described for Orchard 
I, each tree being thoroughly sprayed once and carefully re- 
touched twice. The trees were not trimmed, however, after the 
spray had been applied. Owing to a leaky pump and poor noz- 
zles the amount of mixture averaged nearly three gallons per 
tree in this orchard. McGowan nozzles were used. The mixture 
was made in a large iron kettle holding about 60 gallons, which 
was heated by an open fire. 
During the thirty days immediately following the treatment 
the weather was usually cloudy, there being but seven days of 
fair weather. From April 3 to May 4 there was rain or snow on 
nine days, as follows: April 3, snow squalls; 6, light rain at 
night; 8, light rain afternoon and night with high wind followed 
by heavy rain and wind, lasting most of the following day; 10, 
light rain most of the day; 11 and 12, light showers; 26, heavy 
showers in the morning followed by light rains the remainder 
of the day; 29, moderately heavy rain at night followed by 
heavy showers the following night; May 8, light rain followed 
by heavy showers the following day. 
Results on plums.— The same general effect was noticed here as 
on Long Island. On the average the buds were about a week 
late in opening, but otherwise there was no apparent effect on 
the trees. Especial pains was taken to discover any injury to 
the fruit buds, but there was no evidence that they were injured 
in the slightest. The trees bore fully as much fruit and in some 
cases more than the uninfested trees. 
Results on peaches.— The effect on the peaches was practically 
the same as on the plums. 
Effect on the scale.—-The comparatively few trees in this 
orchard that were encrusted with the scale did not give as good 
opportunity for observing the effects on the scale as in some of
