bran mash. Would it have been equally efficient if the foliage had 

 been succulent? 



Mr. George A. Dean: The drouth conditions in my opinion 

 aided greatly. These grasshoppers had come two or three miles 

 and were very hungr3^ It was very hot in Kansas and they sought 

 shady places. They preferred to do their feeding in the shade and 

 the drouth conditions aided greatly in getting the grasshoppers to the 

 poisoned bran mash in shady places. 



Mr. J. G. Sanders: Has a test been made of artificial or syn- 

 thetic orange flavor? This material is verj^ cheap. 



Mr. George A. Dean: I have used extract of lemon and other 

 things, but believe that if the orange fruit is ground up with the peel- 

 ings, that it is more attractive to the hoppers. 



President P. J. Parrott: The next paper on the program is by 

 Mr. Z. P. Metcalf on "Report of Field AVork on the Southern Corn 

 Bill Bug."

Mr. a. F. Conradi: I would like to ask Mr. Metcalf what he would 

 recommend in practice to avoid the ravages of the corn root worm. 



Mr. Z. p. Metcalf: In North Carolina, as far as my observa- 

 tions and experiments have gone, the dates for planting to avoid 

 infestation of the corn bill bug coincide exactly with the dates for plant- 

 ing to avoid the corn root worm. Very early plantings seem to escape 

 injur}'^ and the same is true of very late plantings. 



President P. J. Parrott: We will now have a paper by Mr. 

 A. F. Burgess on "The Present Organization and Methods Used by 

 the Bureau of Entomology on the Gipsy Moth Work."
