Orchard IIT: Plums.—tIn the early spring the trees treated 
with the self-boiled lime-sulphur-salt wash showed more injury 
than the trees sprayed with the other washes. On some of the 
trees there was a destruction of nearly one-half of the leaf-buds. 
The remainder of the plums showed fewer leaves on the lower 
and inner spurs than the checks. However, the increased growth 
of the new wood caused a great improvement in the appearance 
of the sprayed trees which subsequently fully equalled the checks 
in quantity of foliage and fruit yields. The previous yield of 
plums was practically worthless from scale injury, but this year a 
clean crop was marketed. 
Orchard IV: Plums.—The self-boiled caustic soda wash caused 
severe. injury to a tree which was evidently weakened by scale in 
the previous year. Otherwise the condition of the sprayed trees 
was satisfactory and remained so throughout the summer. 
It is well to mention that applications of the kerosene-lime 
washes in this orchard gave varying results and in some instances 
caused very severe injuries. A number of trees were killed and 
the remainder were so injured that they produced only about 
one-quarter of a crop of fruit. The trees treated with the sulphur 
wash yielded a full crop of fruit and on Aug. 15 were.in much 
better condition than those treated with other sprays. 
Orchard V: Peaches.—Karly in the spring a comparison of 
sprayed and unsprayed peaches showed no apparent differences 
with respect to fruit and leaf buds. The varieties treated with 
the self-boiled caustic soda wash were the more exposed to the 
severe winds and on March 27 Mr. Sirrine reported a consider- 
able shriveling of the young wood. Checks under similar ex- 
posure were less severely injured, while the trees receiving an ap- 
plication of the boiled sulphur wash were somewhat less exposed 
and consequently the injuries from this source were not as con- 
spicuous. An examination on May 6 showed that 75 per ct. of 
the spurs on all the trees were killed, and it was evident from the 
condition of the checks that less than 10 per ct. of the injury 
on the treated trees was due to the spraying. 
Effect on curl.—Peach leaf curl was present on both sprayed 
and unsprayed trees. The sprayed section had 1.5 per ct. of 
curled leaves as compared with 85 per ct. of curl on the checks.
