The fariiier will know him better and will soon have more confidence

The entomologist, too, will have more respect for the farmer and 

 h.is methods, and more interest in him and his particular problems 

 because of the contact. It Avill prove mutually advantageous. 



The literature of economic entomology has been discussed several 

 times in the meetings of this Association, but I wish to mention it here 

 on account of its bearing upon my subject. Some official entomologists 

 publish annual reports. Others publish in the reports of the institu- 

 tions with which they are connected, and such reports appear to be 

 a fit place to publish the full accounts of any experiments or inves- 

 tigations, or descriptions of methods and technique. Descriptions of 

 new species or important facts regarding the life history or habits 

 of an insect should be published in monographic treatises or in ento- 

 mological journals. These publications are of great service to other 

 workers, but do not as a rule appeal to the popular mind, especially 

 if somewhat technical in their nature. 



The popular bulletin or circular fills a distinct place in the list of 

 publications of any official entomologist or experiment station worker 

 — and I believe this has been conceded by those who have previously 

 discussed the matter. Such a bulletin should give a brief, concise, 

 non-technical account of the insect and directions for its control. 

 Though we can place no definite limits as to the size of such a bulletin 

 or circular, in general it should be brief. Often all that it needs to 

 contain can be told in four or six, and seldom requires more than 

 twenty-four pages. If very long, it should be provided with a table 

 of contents and a brief summary. Illustrations are of the utmost 

 importance in the popular bulletin, but they should be good ones. 

 Photographs of insect injury are usually better than drawings, and 

 the larger species can be shown very well in photographic illustra- 

 tions. There are many details, however, that can be shown only by 

 drawings, and zinc cuts are often used for all the illustrations. 



Such a bulletin as I have mentioned is usually sent to all names 

 on the mailing list. But there is frequently a demand for another 

 form of imparting information, and some experiment stations issue 

 special bulletins or circulars either to convey brief, timely information 

 or to assist in the correspondence. Several forms of these have been 

 given a trial at the Connecticut Station at New Haven. For instance, 

 aside from our numbered series of reports and bulletins, we issue 

 occasionally the "Bulletin of Immediate Information," which is 

 mailed, not to the names on the regular list, but to a certain class, 

 such as fruit growers, truck growers, dairymen, or nurserymen. This
