side of the trunks and also on the underside of the larger 
branches. The condition of these trees was nearly as satisfactory 
as those of the experimental row sprayed by the writer. | 
A large number of trees below the experimental rows were also 
sprayed later with the lime, salt and sulfur mixture, which had 
been boiled till the amber color was very apparent, and the appli- 
cation was fully as thorough, according to the statement of the 
owner. <A considerably larger number of living scale insects 
occurred on these lower rows, which may possibly be due to the 
fact that these trees were somewhat more infested in the spring ; 
though this hardly seems an adequate explanation for the 
difference. 
The extended breeding period of the San José scale was strik- 
ingly illustrated by finding a few living young and a great many 
in the white stage at the late date of Nov. 25. All the treated 
trees were then in a very thrifty condition and bore immense 
numbers of fruit buds. 
Experiments at Warwick. The same mixture was applied Mar. 
24 and 25 to some old peachtrees in the town of Warwick, Orange 
co. The mixture was prepared according to directions given 
above, and, owing to its not being very thick on some trees, a 
number were resprayed the second day. The applications in both 
instances were made on bright, rather sunshiny days, though there 
was some wind in the afternoon. Rain commenced to fall in a 
slight drizzle Friday afternoon, the 28th, and during the night it 
rained very hard. An examination the following morning showed 
that very little of the mixture had been washed off. 
An examination of these trees July 8 showed little that was 
decisive. A few scales were living, and the same was true of 
untreated trees, and therefore no definite conclusions could be 
drawn. Fruit buds appeared not to have been affected by the 
application, and the trees did not seem to be harmed in the 
slightest. 
An examination Noy. 24 failed to give anything decisive with 
this material. The trees sprayed with this substance were in as 
good condition as those treated with the crude petroleum or the 
whale oil soap solution, but the difference was not marked enough 
to warrant the drawing of any conclusions unless it be that the
