INSECT PEST SURVEY 
Fr. D. Butcher, Extension Entomologist, is making an extended trip 
through a large portion of his territory. He will visit Missouri, Kan- 
sas, Colorado, Wyoming, Montana, Iowa, and Illinois. During this trip 
special attention is being given to the control of botflies. On August 
13 to 16, he attended the meeting of the Great Plains Crop Pest Com- 
mittee at Bozeman, Mont. He will return to Washington about September 30. 
M. P. Jones attended the "potato tour" of the Eastern Shore of Vir— 
ginia on June 18, of Maryland on June 19, and the 14th Annual Long Island 
tour on June 24 to 26. Several farms were visited on each tour and on each 
farm the operator had a demonstration plot to portray some of the better 
practices in potato growing, including seed selection, fertilisation, 
and the control of insects and diseases. Mr. Jones considers the potato 
tour one of the best methods of passing experiment station results to the 
growers. He states that it is very gratifying to see the close coopera— 
tion which exists between the farmers, the extension workers, the re— 
search workers, and the commercial men.
