financially in getting a better forest product, both in volume and qual- 

 ity, than would have happened had the insects never appeared. 



From the experience gained already, we have demonstrated that 

 where we have a clean stand of pine the forest can easily be pro- 

 tected against the gypsy moth. There are few species of forest prod- 

 ucts worth more than white pine to grow commercially at present here 

 in Massachusetts. What is true of the pine is more or less true with 

 other evergreens, hence in the gypsy moth infested territory it is good 

 forestry to grow these species. 



The first thing to be done, therefore, with all woodlands is to prac- 

 tice modern forestry management for the benefit of future products 

 regardless of gypsy moths or other depredations; then let come what 

 may conditions are of the best to overcome them. 



There is little to be gained in treating egg clusters and combating 

 moths on dead or ill shaped and weed trees and stumps, as one's 

 efforts ought to be centered on those that have prospective value. 



We are recommending, therefore, that everyone begin at once to 

 practice modern forestry management and then the insect warfare 

 will be greatly reduced.

SOME INSECTICIDE METHODS USED IN COMBATING 

 THE GYPSY MOTH 



By A. F Burgess, Washington, D. G. 



From the time that the gypsy moth first became destructive in 

 Massachusetts and active measures were begun to secure its control 

 and suppression, an effort was made to devise cheap and effective 

 means of attaining that end. The results of a large number of experi- 

 ments have brought about the adoption of a system of treatment 

 throughout the year, which is very effective in controlling the pest, 

 although the expense involved precludes its use in woodland areas of 

 low valuation. The purpose of this paper is to point out some of the 

 methods which have been found effective, and draw attention to their 

 possible utility in combating other insect pests. It is hoped that this 

 may lead to a discussion of the methods used and that it will be pos- 

 sible for some of them to be tried experimentally in other parts of the 

 country. 



Treatment of Egg-Clusters. The egg-clusters of the gypsy moth 

 are laid in masses which are covered with hair from the bodies of the
