points. We need more knowledge with regard to the sensory reac- 

 tions of insects, their relation to chemicals, to temperature, to light, 

 to vibrations. We need to know more about the mouth structures, the 

 foot structures and the actual method of disease-transmission. It 

 is essential that the student become familiar with the habits and hab- 

 itat of the insect in the field, its life history under normal and un- 

 usual conditions. This plan has been followed out in our study of 

 the housefiies and the flesh flies, and it is upon such knowledge that 

 our present campaign against the housefly in Berkeley rests. Thus 

 we are also developing our work on the fleas, the mosquitoes, the fruit 

 flies, the stable fly, and the Texas fly. 



PUBLICATIONS OF THE STATION ENTOMOLOGIST

The matter published by the Station Entomologist divides itself 

 naturally into three classes — that published primarily for the informa- 

 tion of his constituents and embodying matter which does not neces- 

 sarily originate with him ; second, reports of experiments and investi- 

 gations made ; and third, technical scientific articles. This matter 

 is published in a variety of forms, as circulars, press circulars, bul- 

 letins, annual reports and articles in technical periodicals. The 

 whole matter of the best methods and system for Station publications 

 is now in such a state of development that it is impossible to lay down 

 any principles with which all will agree, and the speaker merely 

 wishes to attempt to outline some principles which seem to be gener- 

 ally supported by the Stations having the better class of publications. 

 First let us consider the bulletin, for it is ''par excellence" the 

 publication characteristic of the American Experiment Station. In 

 the past the bulletin has included almost anything from a general 

 compilation of various injurious insects, with the remedies for the 

 same, to a bibliography of some group of insects or an account of 

 some pest, giving its anatomy, embryology, etc. etc. More and more 

 we have come to feel that the bulletin should be essentially a farmer's 

 publication. In its construction the writer should constantly strive 

 t6 put the matter in such shape as to attract and interest the reader. 

 'We should prefer a bulletin not over 32 pages long, certainly never 

 -Oven' 48 pages and preferably a single form of 16 pages, except where 

 a general handbook, such as a manual of all the insects injurious to 

 -frtiit^'oi'' gaMen crops, or something of that sort, is to be published for
