out to took at the conditions. The infestation was much more 
severe and had spread to adjoining fields. A few dcays later 
I demonstrated o.i a fev/ stools of cane how easily the rymphs 
and adults ccu3d he killed with calcium cyanide dust. However, 
the manager was afraid he might also kill some Haitians, which 
would he an expensive matter, and nothing was done in the way 
of control. About a month ago I visited the field and found 
that the infestation had almost disappeared, so much so indeed 
that the class demonstration that I had planned was not an entire 
success. More recently the manager reports the insects all gone, 
Or at least so nearly gene as to he causing no damage,

PERIODICAL CICADA ftPlbiclna' sentendecim L.) 
Louisiana W. E. Hinds (July 22): With reference to the possible appearance 
of the periodical cicada in Morehouse Parish, I would-. say that I 
did not see specimens and am not positive as to the ieeutif icatio 
of the species. Professor Horned has written raising a question
