BULLETIN 204, U. S. DEPARTMENT OP AGRICULTURE. 



egg clusters were found. A considerable area was scouted around the 

 infestation, and egg clusters or caterpillars were found over an area of 

 about three-fourths of a square mile. Many of the trees were growing 

 on rough and rocky soil, so that it was very difficult to do thorough 

 work. About 1 5,000 egg clusters were treated during the month of May. 



In addition to the scouting work already mentioned, a special 

 examination was made of the entire town of Geneva, N. Y., but no 

 gipsy-moth egg clusters were found. In 1912 a small colony was 

 found in this city. It has been very thoroughly treated by the 

 assistants of the commissioner of agriculture, and it is now believed 

 that the insect has been exterminated. The scouting party detailed 

 for the Geneva work spent one week in examining trees in Seneca 

 Park, Rochester, N. Y., but no traces of the moth could be found. 



Special scouting work was carried on in the towns of Lenox, Stock- 

 bridge, and Great Barrington, Mass., during the winter. Infestations 

 have previously been found in these towns, but the examination 

 resulted in finding but one egg cluster in Great Barrington, one in 

 Stockbridge, and two in Lenox, indicating that good results have been 

 secured from the treatment which had been applied during the pre- 

 vious season. A careful inspection was also made in the town of 

 Wallingford, Conn., which was found infested some years ago, but no 

 egg clusters were discovered. 



The following table shows the number of towns which have been 

 scouted for the gipsy moth and the number of new towns which 

 Were found infested during the winter of 1913-14.

In nine towns in New Hampshire and two in Massachusetts, infested 

 in 1912-13, no infestations could be found the following winter, and 

 recommendations were made that these towns be excluded from the 

 quarantined area. This was approved by the Federal Horticultural 

 Board, and the border towns of the area quarantined for the gipsy 

 moth include only those that have been found infested during the 

 past winter. 



The plan of the work has been to examine the territory in Maine 

 chiefly for the purpose of securing data as to where the quarantine 

 line should extend. It is impossible to prevent the spread of the 

 small caterpillars by the wind, and it has therefore been deemed 

 advisable to confine the clearing-up work along the border to the ter- 

 ritory in New Hampshire, Massachusetts, Rhode Island, and Connec-
