326 ANNUAL REPORT 



full answers to all inquiries in regard to them, recommending 

 such remedies or tretment that are known to be most effective. 

 By the formation of biological collections of all insects found 

 to be injurious to some crop or industry, much would also be 

 done to disseminate a correct knowledge of insects among the 

 people; such collections to be placed for convenient study or 

 inspection to all it may concern, by being exhibited at the 

 meetings of the different societies, or at the annual fairs. To 

 give you an idea of what I mean by such biological collections, 

 let me call your attention to the two cases of insects that were 

 hastily put together from such material as was at hand, in order 

 to illustrate this point. The one containing insects injurious to 

 the cabbage, illustrating a paper on this subject in the thirteenth 

 annual report of the survey; and the other containing some of 

 the insects found to be injurious to the apple tree. As I have 

 not yet had opportunity to study the insects injurious to the 

 apple, I have most of these only in the imago state, though a 

 properly arranged collection of this kind would contain each 

 species in all its stages, from the egg, larva, or worm-stage, 

 during which most of the injury is usually done, the pupa or 

 chrysalis state, to the imago, or fully developed insect. Such a 

 collection properly named, and if reference to published articles 

 on species be added, would give a great deal of information in 

 the shortest time possible, and be profitable to every intelligent 

 observer. 



Although it is the ainj^ of the survey, in as far as it is able to 

 undertake the work of entomology at present, to reach the best 

 and most practical results that are consistent with good scien- 

 tific woi'k, yet I think the immediate wants are such, not only 

 for you as horticulturists, but for many others, as would call for 

 the appointment of a state entomologist with the necessary ap 

 propriations to enable him to devote his whole time to this 

 work. 



DOES IT PAY TO HAVE A STATE ENTOMOLOGIST ? 



From the conduct of such states that have already undertaken 

 this work, we would say that it does pay. Illinois has for the 

 past fifteen years had her state entomologist, and twice on the 

 death and once on his removing from the state, has his successor 

 been immediately appointed. New York, the Empire State, 

 had her state entomologist in the life-long work of Dr. Fitch,
