Mr. J. J. Davis: At 165 pounds to the acre it sometimes burned 
the grass slightly, but it did not destroy it outright, excepting where 
there were holes and where the solution stood for a length of time. 
There is no effect on any future crop; the cyanide disappearing 
within ten days to two weeks. We cannot apply it where there are 
growing, cultivated crops, like corn, without injury.

OUTLINE OF PROJECT WORK IN EXTENSION 
ENTOMOLOGY 
By E. G. Kelly, Extension Entomologist of the Kansas State 
Agricultural College 1 
Extension work in entomology means the carrying to the farmer, 
the ranchman, the gardener and the fruitgrower information as to 
the how, when and where of the methods of controlling his insects 
pests. In order to do this a definite plan must be made by the leader 
Furthermore, to put over a plan or project of so much importance as 
the one herewith presented it is necessary to have an effective organi¬ 
zation. In Kansas we have such an organization in our Extension 
Service, namely the County Farm Bureau. Each County Farm 
Bureau has a county agent who is a member of the Extension Division. 
The extension entomologist, who is the leader of this project, is also a 
member. The county agent is the medium through which the ento¬ 
mologist reaches the farmers. 
You will please note that the project deals first, with the combative 
period—meaning the time control measures may be effected—and 
second, with the educational period. The combative time may be 
during the active period of the insect or may be during the dormant 
period; the educational time should be any time convenient for a 
gathering of farmers. 
Where there are a large number of county agents in a state, the time 
the entomologist can devote to each agent must be necessarily limited. 
In Kansas we have 60 county agents with the state divided into con¬ 
venient conference districts. Definite dates are set on which to hold 
a conference each month; a special conference may be called any time 
in case of an emergency. The entomologist attends these conferences 
whenever it is desired and gives the county agents definite instruction 
as to handling the insect problem at hand. These conferences are 
held in the office of the Farm Bureau near the district center. The
