V. I. Safro of the Kay Laboratories, New York City, recently spent 
a day at the laboratory at Moorestown, N. J., discussing insecticidal 
problems with the members of the staff.

the larvae of the Japanese and Asiatic beetles, and the nurseryman was 
advised to treat his soil with lead arsenate. 
A conference was held at the Moorestown laboratory on May 9 to con- 
Sider the recommendations for spraying fruit trees and ornamental stock
