thirty miles of the various points of liberation. The drift was largely south- 

 easterly, widely scattering individuals landing here and there over the intervening 

 territory to both eastern and southern New England coasts. Several were found 

 on Long Island. There were 285 balloons which drifted a total of 9,419 miles, 

 less than 2 per cent, being in a westerly direction. The distribution of the 

 recovered tags is shown on a map of New England published in the Thirteenth 

 Annual Report of the New York State Conservation Commission for 1923. See 

 insert facing page 168. 



The important point in this work is that practically all the drift was easterly, 

 northerly or southerly, there being less than two per cent, in a westward direction. 

 An examination of the data, see page 165 of above cited report, shows perceptibly 

 more westward drift from the Connecticut valley stations than from any on 

 either the eastern or western sides of the Berkshire Hills, and this in spite of the 

 fact that a number of balloons released west of the range drifted over it. One 

 was observed drifting over the summit of Mt. Everett, elevation 2,624 feet, in 

 southwestern Massachusetts. 



Both wind records and balloon data of 1923 indicate considerable less 

 probability of young gipsy-moth caterpillars being carried westward by the 

 prevailing winds than in any other direction, and present indications in this 

 respect are therefore favourable to the maintenance of a barrier zone. 



WILL THE GIPSY-MOTH CROSS THE INTERNATIONAL 



BOUNDARY ?

It is possible that this has already happened, or will in the near future. If 

 it has not, it surely will unless immediate action is taken to determine whether 

 or not it is present, and necessary funds furnished for extermination, wherever 

 it is located. 



The traveller, regardless of his mission, if crossing the international boundary 

 is subjected to certain international regulations. Will insects be privileged in 

 this respect, especially so in the case of the gipsy moth, which has already located 

 near the border? 



International laws can be quite efficiently enforced in so far as the public is 

 concerned. Insects seem to make a special effort to evade laws and regulations. 

 An immediate exceptionally strenuous effort must be made if the gipsy moth is 

 to be prevented from becoming firmly established in the Dominion of Canada. 



There are at this time in New England many who have been continuously 

 engaged in gipsy-moth work for twenty or more consecutive years. It is doubtful 

 that one can be found who, twenty or in fact ten years ago, realized that we would 

 be continuing the gipsy-moth fight on the northern border of the United States 

 to-day. 



As reference has been made to the period of years that gipsy-moth sup- 

 pression work has been carried on in the New England states, it is only natural 

 that many will consider — is this problem worth further consideration? 



Probably a few figures on the cost of the gipsy-moth suppression campaign 

 in New England will clearly indicate that the problem is not only worth consider- 

 ation, but more serious consideration than it has ever received.
