Mr. Gossard: When I w.is located at the Florida station. I think 

 we hardly needed an insectary, except large wire cages or something 

 of that description. 



I agree that an insectary is, at least, a great convenience at times, 

 and either that or a building of some kind is a necessity. I believe 

 the insectary is useful, but it should not be relied upon too nuich. In 

 other words, you cannot depend upon results that you get in a green- 

 house for out-of-door conclusions. I like, when I am working upon 

 life histories, to have cages in the insectary, because you can isolate 

 your insects, and if they, as they nearly always do, come out a few 

 days earlier, it gives you warning to look for them outside. A great 

 amount of glass I do not think is needful. At the same time, we 

 have a large greenhouse at the Ohio station, and there have been times 

 when I have had it completely filled. Again, it would be vacant for 

 six months at a time. 



E. D. Sanderson : ]\lr. Chairman, I may have misstated this <iues- 

 tion. It should have been possibly. "Do we need a glass insectary?" 

 There, seems to be a difference of opinion on that point. I think Pro- 

 fessor Bruner's point about the desirability of a glass insectary for 

 instruction w^ork is a good one, but it seems to me that there is quite 

 a question whether a more open insectary, giving more natural condi- 

 tions than the glass house, is not better for breeding purposes. As 

 far as parasites are concerned, they are handling as many parasites 

 at Melrose Highlands as any place, and I don't believe that you can 

 get life histories that are worth anything in a glass house when you 

 check them up with what you actually find out of doors. What is 

 the use of making lengthy life history studies which we know do not 

 take place out of doors? We certainly do want a glass insectary for 

 some classes of work, but it does seem to me that we have done a great 

 deal of life history work in glass houses, and if we had cheeked up 

 carefully, we would have found a good deal of ditt'ercnce between 

 what occurs there and out of doors. 



Mr. Slingerland: Mr. President, I must object to some of these 

 points. I don't think ray indoor life histories are so very much dif- 

 ferent from those secured out of doors, and the indoor work gives 

 me experience that helps a good deal out of doors. 



Mr. Hinds : Mr. President, the remarks made have been very in- 

 teresting to me, because we have that question under consideration; 

 that is the establishment of an insectary. I have been very much 

 interested in the plans of Mr, Woodworth, of California, for he is 

 going to have an open court, walled in and a roof to cover a part of 

 the court, so that in rainy weather he can examine the specimens un-
