tinyiiish between "In-eeding'' and " rearin^i. " ' We are doing a great 

 deal of breeding, generation after generation, the offspring of per- 

 haps one pair, and there is no waj^ that we can do that ont of doors. 

 Yon have got to have some place where yon can follow the little 

 creatures, almost microscopic, and breed the progeny through the 

 different hosts. We can't follow out matters like parthenogenesis 

 and polyembryony in the field or stud}^ a great many of the more 

 minute points under tield conditions. 



Mr. F. L. AVashburn: Mr. President, it is not right to throw 

 stones when you live in a glass house, but it seems to me that the 

 statement of Professor Sanderson reminds us of the fox and the 

 grapes. He has no insectary, and we have. We have an insectary, 

 and in our cold room the conditions are just the same as outside 

 during winter, fall, and spring. We can control the insect so that 

 we can observe it, which we cannot do if we depend upon outside work. 



]\Ir. Bruner : The persons who have been talking up to this time 

 have spoken entirely on the experimental side of the work. From the 

 standpoint of the teacher, I believe an insectary is indispensable. 

 You have your students in the fall, winter and early spring, when 

 outdoor conditions do not enable them to study the life history of the 

 insect. If you live in the West, you sometimes have insect attacks 

 or outbreaks three, four or five hundred miles away from headquar- 

 ters, and you must have an opportunity to bring the insects in to study 

 and rear them under observation. The insectary in both of these 

 cases is absolutely necessary. 



INIr. J. B. Smith : I do find that when it comes to the question of 

 merely observing the life history of an insect and trying practical 

 methods for its extermination, I can do better in the field than I can 

 indoors or in an insectary. For certain kinds of research work, an 

 insectary, I can conceive, is absolutely indispensable. For mere eco- 

 nomic work and for ascertaining means for insect control. I don't 

 think the insectary is necessary. I started out with the idea that I 

 wanted one the worst way, and for five or six years I worked very 

 hard to get one, but I did not succeed, and I finally concluded that 

 I did not want one. I have none at the present time, and I get along 

 just as well without it. On the other hand, I do not do a great deal 

 of the kind of work that requires close attention, and "breeding," as 

 Professor Webster defines it. If I were doing work of that kind, I' 

 should feel that it was aljsolutely necessary. 



AIr. H. T. Fernald: Mr. President. I think Professor Smith has, 

 in a way. struck to the root of the matter. ■ Everything depends upon 

 the subject upon which you are at work. I have come to feel the
