working singly. It is certainly advisable that the nests of these 

 valuable allies <it' man should not be disturbed by the cranberry 

 grower, and these observations' suggest the possibility of developing 

 the use of ants as a means of combating these pests on dry bogs, either 

 by encouraging the species already present, possibly by the use of ar- 

 tificial nests, or if possible, by the introduction of some closely allied 

 but more prolific species. 



President Forbes : Any discussion of this paper ? 



Mr. K. L. Webster : ]\lr. President, I was very much interested 

 in the remarks on the cranberry worm, inasmuch as I have just fin- 

 ished some experiments on its life history in Iowa, where the insect 

 is a pesf on apple stock in the nursery. In southern Iowa, and as far 

 north as Des Moines, this species is three-brooded, and there was 

 no indication of the difference in the color, either in the head or in 

 the general color of the larva?. I found no larvte on apple, which I 

 could call red-striped, in any sense of the word. The three broods, 

 as far as I could see. all had the same appearance. 



Early in the spring, I found eggs only on the lower part of the 

 apple trees in the nursery. They seemed to be deposited before the 

 leaves had come out very far on the trees, all on the lower part of 

 the trees, perhaps within a foot or six inches from the ground. In 

 this way, only the lower limbs on the trees were infested. The leaves 

 higher up did not have anj^ larvae at all. The remaining two broods 

 deposited eggs, as far as I could determine, on the leaves. I saw 

 none at all on the limbs, as in the case with the first brood. In 

 the second and third broods the larva? seemed to be feeding all over 

 the trees, principally in the tips of the young growing leaves. The 

 first and second broods of moths were the orange form, and the last 

 brood the slate form as in New Jersey. 



President Forbes: Anything further on this subject? 



Mr. Hopkins : Mr. President, I think the matter has come up 

 before this Society before, and while we are considering the matter 

 of nomenclature, we ought to settle on the use of the terms " brood '^ 

 and "generation." Sometimes it is necessary to refer to the parti- 

 cular brood. It seems to me there ought to be a certain uniformity. 



President Forbes : The following paper will now be presented : 

 "An Example of Forest Insect Control at a Profit," by j\Ir. A. D. 

 Hopkins. 



A. D. Hopkins: Mr. President, I did not expect to present this 

 paper, but, owing to the fact that a rather striking example was
