44 JOURNAL OF ECONOMIC ENTOMOLOGY [Vol. 3 



Mr. Headden : The only record I have along this line is the ease of 

 an ehn tree which had been sprayed. Analysis showed a large amount 

 of arsenic in samples taken from this tree. 



Mr. Gillette: It is probable that orchards will ordinarily suffer 

 more than forests, for the reason that most of them are cultivated, 

 which serves to work the poison into the ground and bring it in con- 

 tact with the roots more rapidly than would be the case in forest 

 areas. If the orchard is irrigated, this would also tend to convey the 

 poison to the roots more readily than if artificial watering was done. 



President Britton: While we are discussing the gypsy moth, I 

 think it will be well to hear from the officials in various New England 

 states who are engaged in the work- of suppressing this insect, and I 

 will now call on Professor Hitchings from Maine. 



Mr. Hitchings: Our work in Maine has followed along the same 

 lines as that in Massachusetts. We, in ]\Iaine, have felt that we could 

 not improve on the system adopted in Massachusetts, where the insect 

 has been fought for many years, as our conditions are quite similar, 

 and therefore we have been carrying on the work in the same way. 



In Maine, the field Avork is in charge of a special agent appointed 

 by the Commission of Agriculture, who has charge of the men. The 

 force is divided into sections, and we feel that very effective work has 

 been done in controlling the insect and keeping the infested section 

 in good condition. 



The situation at the present time is a serious one, and it is neces- 

 sary for every effort possible to be put forth, in order to hold our own 

 in the conflict. Our investigations lead us to believe that in some 

 localities the young larvfe of the gypsy moth must have been carried 

 by birds or four-footed animals. The locations of some of the colonies 

 in the woodlands gives strong evidence that this is the case. 



President Britton : I notice that Captain Philbrook is in the audi- 

 ence, and as he is the special agent, having charge of the field work 

 in Maine, I know you will all be glad to hear from him. 



Mr. Philbrook: I don't know as there is anything to add to that 

 which has already been said. 



I might mention one point which has not been touched upon — in 

 regard to the spreading of the moth — and that is that invariably in 

 woodland colonies we find that at some time previous a portable saw- 

 mill has been temporarily located in the vicinity. In some cases these 

 sawmills have been shipped from localities badly infested with the 

 gypsy moth, and this evidence shows that the insect can be distributed 

 in this way.
