device, it is possible for sufficient pressure to be maintained to spray- 

 trees seventy to eighty feet high without climbing them. 



I trust as many of the members as possible will examine these spray- 

 ing devices, jvhich are being used in this section, and we should cer- 

 tainly be glad to receive any suggestions looking toward their further 

 improvement.

CARBON DI-SULFID FUMIGATON FOR THE RICE 



WEEVIL IN CORN 



By W. E. Hinds and W. F. Turner 



At the meeting of the Association of Economic Entomologists held 

 in Baltimore one year ago, announcement was made of a project for 

 the investigation of the use of carbon di-sulfid as a fumigant. An out- 

 line of this project was given, and also, in a separate paper entitled 

 "Carbon Di-Sulfid Fumigation for Grain Infesting Insects," a brief 

 statement was made as to results obtained up to that time. The work 

 of this investigation has been continued during the past year with a 

 gradual increase in the scale of the experimental work as the results 

 obtained have seemed to demand and warrant. 



In addition to the project upon fumigation, another project for 

 the investigation of the life history, economic relationships and injury 

 of the rice weevil {Calandra oryza L.) has been approved for the Ala- 

 bama station. The imperative need for work along the lines contem- 

 plated in each of these projects has been frequently emphasized dur-
