REPORT OF THE STATE ENTOMOLOGIST 1901 TOL 
There has been an unavoidable break in the office caused by 
the resignation of my first assistant, Mr C. S. Banks, who severed 
his connection with the office July 15, a particularly unfortunate 
time, since it is the season when insect activities are at their 
hight. Miss Margaret F. Boynton was promoted to the position 
of first assistant, and Mr C. M. Walker, who has been an ad- 
vanced student in entomology for nearly two years under Prof. 
©. H. Fernald of the Massachusetts agricultural college and who 
was the special assistant in the preparation of the collection for 
exhibition at the Pan-American exposition, was appointed second 
assistant. 
Special investigations. Three lines of work mentioned in my: 
previous report have been prosecuted during the past season. 
1 The series of experiments with insecticides for the control 
of the San José scale have been carried on in the same orchard 
as last year, and the results obtained in 1900 have been largely 
confirmed. Fuller details of this work will be found on sub- 
Sequent pages, 
2 The study of forest and shade tree insects has been con- 
tinued, and many of the observations of previous years have 
been prepared for publication, and those of this season will be 
put in a similar condition as soon as possible. 
3 The special study of aquatic insects, begun in 1900 has also 
been continued. It is noticed in the following paragraph. 
Entomologic field station. The work commenced at Saranac Inn 
in 1900 was continued at Ithaca N. Y. in cooperation with the 
Cornell university authorities. Dr James G. Needham of Lake 
Forest university, Lake Forest Il. was in charge of the work, 
as last year. It was largely supplemental to the studies of the 
previous season, and Dr Needham’s report will therefore include 
a rather full account of the damsel flies, Odonata-Zygoptera, 
and of the fish food material collected by him at Saranac Inn. 
A family of small flies (Chironomidae), very important so far 
as fish food is concerned, has received special study by Mr O. A. 
Johannsen, an advanced student at Cornell university, and his 
account will also be included in this report.
