In counties having no county agent, local leaders should be found if 
possible and the work done through them. In Kansas, local men who 
through our visits have acquired a good knowledge of spraying are 
constantly called upon for help by others in their community. 
Preliminary to the project work the extension entomologist must 
gather and systematize information from all sources that will be of 
value in his state. Much of this must come from co-workers in his 
college and this necessitates close cooperation with the departments of 
the college and especially the Department of Entomology. He 
should not overlook valuable information from other institutions and 
must serve as a sieve to separate out the published results of research 
work which will be of value in his state, and also see that the control 
measures selected thereby, before given to the farmers, are practical 
for them to use. 
Planning the annual project in the field calls for a yearly program 
that will be continuous and efficient in addition to being in advance of 
emergency calls. The greatest part of the project work will consist in 
securing the application on a practical basis of the control work out¬ 
lined, and this will call for perhaps 90 per cent of the time of the en¬ 
tomologist engaged in extension work. At the same time he will want 
to make some part of his control work research in nature to keep alive 
in him the love for new facts, and as Prof. R. A. Cooley states in his 
excellent paper read before the Special Meeting of this Association 
at Berkeley, California, in 1915, 1 to keep alive in him the true spirit 
of the scientist'. 
The extension entomologist has an excellent opportunity to see the 
results of control measures secured under different methods of farm or 
crop management, and, with his experience and training back of him, 
to wisely interpret the results secured by the average farmer under 
average farm conditions. This is illustrated by the work of a re¬ 
search nature done by the extension entomologist in Kansas during the 
season of 1916 with respect to the relation of Hessian fly damage to the 
presence of volunteer wheat in the seed bed at seeding time. 2 In 1917 
an excellent opportunity was afforded to secure results of a research 
nature in demonstrating control work against grasshoppers in western 
Kansas. A comparison of the use of the Kansas poison bait against 
the hopperdozer showed that one application of poison bait killed 4.1 
bushels of grasshoppers per acre, while repeated use of the hopperdozer 
under the same field conditions caught but 1 bushel per acre. Such 
work fits in well with the regular extension work in entomology and
