lots or forests in such ways as to obviate the difficulties. Through 

 our observations we have found that many of our hardwoods 

 species also are comparatively immune from these moths. The 

 ash, locust, hickory and others, if selected and planted inde- 

 pendently of those trees most coveted by the moths, would be 

 relatively free. (See table, page 285.) If, in addition to 

 silvicultural methods, as indicated, we also practice up-to-date 

 forestry management by keeping the stand thinned out of dead 

 wood and inferior and weakened trees, the results would be appre- 

 ciable. Forest fires running through woodlands leave them in 

 an unhealthy and unprofitable state, and it is here that moths 

 and other depredations get their start, as the owner loses interest 

 in such growth and feels it is not worth working with. These 

 become the breeding places that later cause so much trouble. 



With modern methods of management our forests will improve 

 in every way. A forest properly thinned is more easily cared 

 for, no matter what attacks it. Wherever we find wild, neglected 

 woodlands, thickets and tangles along highways, or run-down and 

 neglected estates, there are invariably the places where we expect 

 to find the gypsy moth entrenched. 



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

 to practice modern forestry management for the benefit of future 

 products, regardless of moths or other depredations; then let 

 come what may, conditions are of the best for overcoming them. 



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

 insects on dead, decaying or ill-shaped and weed trees and stumps, 

 as one's efforts ought to be centered on those that have pro- 

 spective value. 



The State Forester and his staff of trained assistants stand 

 ready to assist any and every one in the State in the practice of 

 modern forestry management. This once well established we 

 predict that the insect depredations will be largely under control. 



Forest Trees resistant to the Gypsy Moth. 

 With a view to finding out which species of trees are most 

 resistant to the gypsy moth under general forestry conditions, 

 the following data as to the feeding habits were collected by a 

 trained forester. The work extended from July 10 to July 24, 

 in areas which had been stripped by the gypsy moth. Sixty-
