De W. ‘pee in charge of the investigations of parasites affecting 
the European corn borer at Arlington, Mass., recently visited Washincton 
for the purpose of consultation with the parasitologists of the Bureau. 
W. R, Walton, ae: Worthley, and D, 0 Caffrey visited thenwestor 
New York area of infestation duri ng the week of March 21. The party 
was engaged for. the greater part of the time in going over the control 
work which is being carried on in the Silver Creek sweet corn district 
for the purpose of reducing the intensity of the infestation and the pos 
sible prevention of spread. It was found that the work was progressing 
very fadorably under the personal supervision of L. H. Wotthley, as the 
weather conditions were very favorable for burning, and about three 
fourths of the material has been disposed of in this manner. It is 
believed that this work will be completed during the first week of April. 
The area actually treated comprises some 800 oe he te OO acres over which 
the cornstalks and stubble were removed and ¢ x burned or crushed. 
Members of the party also visited the Thoras Indian School in 
company with Doctor Bates of the Cornell Station staff, who is interested 
in persuading the Indians to clean up the infestation on the Reservation. 
It is believed that through his efforts their full cooperation will be 
secured.
