future serve as one of our best methods of educational work with en¬ 
tomology extension. Farmers’ institutes and movable schools not 
only make the work continuous throughout the year, but also serve to 
prepare a community for demonstration work to follow. Many of our 
orchard demonstrations have been located as a result of these lectures 
and through which the communities were made ready for the spraying 
demonstrations. 
Traveling exhibits have just been installed in Kansas and are ex¬ 
pected to speak for themselves and give information at the right time 
for control. They are made up by the extension worker from material 
collected in the community and exhibited at public places only in com¬ 
munities where need for control is known. They are on display in one 
locality as long as the control method suggested can be applied during 
that year. The next year fresh exhibit material will be placed in that 
or other localities as the need for them is apparent. Care must be used 
in determining the places they are exhibited. In our eagerness to 
serve we are often forgetful of the fact that medicine is intended only 
for sick people and scatter our information in localities where it is not 
needed. The writer has often viewed the patriotic advertisement of 
an enterprising fertilizer company which copied the drawings and sug¬ 
gestions of the U. S. Bureau of Entomology in a publication on the 
Hessian fly and incorporating this with their fertilizer advertisement, 
had posters put up under glass in depots in western Kansas where the 
Hessian fly has never been known and where commercial fertilizers are 
not needed. 
We find that exhibit material collected locally and showing the loca¬ 
tion of insects during the time of year they can be most easily destroyed, 
such as grasshopper eggs and chinch bugs, not only attract more at¬ 
tention than posters, but the suggestions accompanying are more apt 
to be used on the farms and thus an outbreak of insects disposed of in 
its incipiency. 
Newspaper articles are of great value when timely and reach the 
largest number of people with least effort. Unfortunately we have no 
way of knowing how much good they do. 
The demonstrational work gets the visible results and stands as 
an object lesson to the community. Work of demonstrational char¬ 
acter must have the right of way and if possible be scheduled well in 
advance. Plans can be made for the control of fruit insects in advance, 
and one knows pretty clearly how niuch time the work will take. In 
Kansas spraying demonstrations for the control of fruit insects have 
been going on for seven years and are distributed throughout the 
eastern part of the state, orchards being accepted for this purpose 
under written contract with the owners.
