necessity for an iiiscctni-y, hceause such an amount of work in Massa- 

 chusetts is related to the yrowing- of greenhouse crops. There is a 

 large amount of crop raising under glass in that state, and the insects 

 are particularly abiuidant on house-raised crops. For such cases as 

 that, insectary conditions are not abnormal, but entirely normal, and, 

 therefore, an insectary or a greenhouse, where you can raise the very 

 crops that are being raised in the forcing houses in the state and 

 apply methods of control to the insects on those crops, is just what 

 you want. If it were out-of-door insects, I should favor the method 

 made use of at the Uypsy i\Ioth Laboratory. I would ver}^ much 

 object to doing without a greenhouse under my own control. On 

 the other hand, there are many months, perhaps, in each year, dur- 

 ing which I may have no use whatever for that house. It simply 

 amounts to this. When I do not want the insectary greenhouse. I 

 do not want it at all. and when I want it. I must have it. 



A. D. HOPKINS: ]\lr. President. ^Ir. Fernald has just covered part 

 of the remarks I was going to make, that tlu^ character of work will 

 determine the kind of insectary. I may say. that in our forest insect 

 work, we have very little use for a glass house insectary. We do need 

 lots of glass, tin cans, tin boxes and paraphernalia of that kind, which 

 are extremely useful in rearing insects from wood and bark. 



Mr. Titus : Mr. President, I want to emphasize Professor Bruner's 

 point, and that is in regard to the distance some of us have to travel. 

 Now, I can go from here to Ogden nearly a day quicker than I can 

 go the length of my own state, so that when it comes to a question of 

 handling plants that live in the southern part of lUah, which do not 

 grow in the northern part of the state, we need a greenhouse in order 

 to have these plants growing, so that when the insects come in we will 

 have something to feed them on, as we never could secure them under 

 ordinary out-of-door conditions. 



Mr. Jones : Mr. President, I would like to pass around some pho- 

 tographs of the type of breeding house that has been used for the last 

 four or five years by the Bureau of Entomology in rearing deciduous 

 fruit insects. Briefly described, it is a shed with a roof covered with 

 shingles or tar paper and with sides of wire screen, such as is used 

 for fencing chicken yards. The interior is provided with shelves 

 to accommodate jars and breeding cages and in the center is a table 

 for similar use. The floor is made of earth, and in it cylinders and 

 flower pots are placed containing insects which pass a part of their 

 development in the gnmnd. This type of house is used at all of our 

 field stations for miscellaneous breeding work. Special devices often 

 have to be made for investigating special insects.
