April, '13] WEBSTER: LOGICAL BULLETIN ARRANGEMENT 181 



synonymy, which is followed by an account of the generations and the 

 stages, and which concludes with a discussion of the natural enemies 

 and the control measures. In using such an arrangement the entomol- 

 ogists in this country seem to have followed the custom of Fitch, Riley 

 and Lintner. Both Riley and Fitch used this general arrangement to 

 a considerable extent but it was most used by Lintner, whose ento- 

 mological articles were almost entirely written up in this historical 

 order. 



Now this is a logical order from the standpoint of pure science. It 

 is perfectly intelligil)le to the entomologist and in consequence it seems 

 proper to use. It is quite natural to lead up to the control measures 

 for an insect after a full discussion of its habits and life history, upon 

 which the control measures depend. 



But an entomologist should write not only for his fellow-entomol- 

 ogists, but for all his readers, and especially for the man to whom his 

 writings ought to be of most use, the man whose crops are damaged 

 by insect pests. Our bulletins are sent to a very large number of 

 people, of whom only a very few know much about insects. The whole 

 mailing list at the Iowa Experiment Station amounts to something like 

 20,000, of which not more than 400 at the most are entomologists. 

 So it seems to me that it is my business to wTite my bulletins, if I am 

 able to do it, for the whole 20,000, rather than only for the 400. 



You cannot expect the average farmer to become an entomologist; 

 the best educated farmer will have difficulty in wading through an 

 entomological bulletin containing any great amount of technical 

 matter. It appears to me that it is the place of an entomologist to 

 become a farmer, so far as he is able, when he attempts to write an 

 article which he expects the farmer to understand. It certainly is 

 not beneath his dignity to attempt such a thing, in fact it is quite 

 possible that he might become a better entomologist and be more 

 appreciated by those who read his bulletins if he should do something 

 of this kind. 



In this connection I may well refer to a portion of the presidential 

 address given before this association in 1893, by Dr. S. A. Forbes. 

 Dr. Forbes said " ... I am inclined to think that we are very 

 likely to forget, W'hen we prepare our reports, that we are writing 

 largely for men to whom entomology is a perplexing, obscure and dis- 

 pleasing subject, of w^hich they know little or nothing, and especially 

 nothing good; but on the other hand, they are frequently experts in 

 crop inspection, far quicker, as a rule, to observe injuries to their crops 

 than we are, and more likely to discriminate them nicely. If we had 

 always borne this fact in mind, I think that our economic articles 

 would usually have taken quite a different form. The crop injury, and
