W. E. Dove, who spent last summer in Alaska investigating insects 
affecting reindeer, returned to the field laboratory at Dallas, Tex., on 
November 19. Much valuable information concerning reindeer bots or grubs 
was secured. 
F. C. Bishopp left Washington, November 8, for a trip through 
the Southwestern States. Stops were made at Dallas, Uvalde, Sonora, and 
Menard, Tex., for conferences with employees stationed at these points. 
The farthest western point reached was Coachella, Calif., where investi- 
gations of the eye gnat, a species of Hippelates, are being carried on. 
On his return trip a stop was made at Phoenix, Ariz., and a short trip of 
inspection in company with T. P. Cassidy and F. A. Fenton was made to the 
cotton area in the Salt River Valley, which was recently found infested 
with the pink bollworm. Mr. Bishopp returned to Washington November 26. 
COTTON INSECTS 
B. R. Coad, in Charge 
Rev. Father Octave Piel, S. J., of Université l'Aurore, Shanghai, 
China, visited the Delta Laboratory on November 27 to obtain information 
that will be of assistance to him in his studies of the cotton insects of 
China. 
Mr. Coad returned to Tallulah in November, from a trip begun in 
August, in the course of which he covered the investigations of the pink 
bollworm in Texas, Arizona, and Old Mexico, as well as the investiga— 
tions of the Thurberia weevil in Arizona. Conferences were held at El 
Paso and Presidio, Tex., Tucson and Mesa, Ariz., and Tlahualilo, Durango, 
Mexico, to outline these investigations. Dr. F. L. Thomas, Entomologist 
of the Texas State Experiment Station, participated in the conferences. 
David Isler, Agricultural Engineer, spent a considerable portion 
of November in the Laguna district of Mexico, where he installed and test— 
ed mills and similar devices for rendering gin trash free from insects. 
The Mexican portion of this project was completed near the end of the 
month, and Mr. Isler returned to Presidio, Tex., to supervise the experi- 
ments in winter plowing and irrigation as measures in control of the pink 
bollworm.: 
Immediately after the discovery of the pink bollworm in the Salt 
River Valley of Arizona, Messrs. Coad, Cassidy, Fenton, and Isler vis- 
ited this district for a preliminary survey. Plans for an intensive 
Study of the situation were formulated and M. T. Young, R. L. MeGeuus 
A. J. Chapman, G. L. Smith, and H. @. Young have been assigned from 
the Tallulah field laboratory to assist in this Survey under the di- 
rect supervision of Mr. Cassidy.
