at Atlantic City, N. J., January 22-26, 1923, having charge of the Bu- 
reau of Entcmology exhibit on the European corn borer, Japanese beetle, 
pea aphis, and other truck-crop insects, A profitable contact was es- 
tablished with many representative canners who had encountered insect 
problems in connection with the production and preservation of their 
crops. The exhibit and demonstration was well attended by delegates to 
the canners' and associated conventions, and it is believed that it has 
more thoroughly exemplified the service which the Department of Agricul- 
ture is attempting to offer to the various specialized agricultural 
~ industries of the country.
