.«". P. Flint (August).: ... .The annual survey which was carried 
on by the 'Natural History Survey and the Bureau of Entomology 
has been completed. This year the survey covered 57 counties 
and the infestation is about the same as last year 7.1th slight 
increase of the fly in parts of the State.' Dry weather has 
reduced volunteer wheat and considerably retarded fly development,

C. M. Packard (July 26): In general, the Hessian fly 
infestation in the East Central States was too light to 
affect yields. There does not seem to be much danger of 
serious infestation this fall in the northern part of this 
region, "he somewhat greater abundance of the fly in the 
southc-rn part of Ohio, Indiana, nnd .Illinois, ^.nd in 
Kentucky and Tennessee, indicates heavier infestations.
