so as to lap slightly and then are fastened in place by a string 

 tied around the center of the burlap. The upper half is then 

 turned down making a double fold. The caterpillars are noc- 

 turnal in their habits, feeding by night. While they are small 

 they remain near their feeding ground but as they grow larger 

 they crawl down the tree in order to find a hiding place. On 

 reaching the burlaps they congregate under the folds away from 

 the light. Here they are found and destroyed. This was the 

 principal method employed during the past season and proved 

 eminently satisfactory. Each field man has as many trees as he 

 can conveniently attend to, turning the burlap each day. One 

 can readily see that this is no place for an unscrupulous man. 

 Only strictly reliable men can be employed in such an important 

 work as this. 



During the past season two thousand one hundred and twen- 

 ty-one trees were burlapped in the infested district. Work was 

 begun at Togus on May J3th, where eighty trees were treated. 

 The most of the burlapping was done during the third week in 

 May. 



The first gipsy larvae were taken under the burlap May 31st 

 at York. 



The first pupa seen was at Eliot on August ist. 



It often occurs that the caterpillars are found pupating under 

 the burlaps. 



SCOUTING DURING THE SEASON. 



The first scouting done in the State was in the fall of 1906 

 when Mr. D. M. Rogers, the National Field Agent, came to 

 Kittery with twelve men for the purpose of covering the prin- 

 cipal highways from Kittery to Portland. They were divided 

 into two squads of six men each. 



These men had been employed in Massachusetts as special 

 scouts in this work. They did not attempt any woodland scout- 

 ing for two reasons, one the lack of time and the other that 

 it was thought that the infestation would occur along the main 

 traveled highway and not in the wood lots. Beginning with 

 Kittery the following towns were scouted with egg-clusters as 

 noted : — Kittery, 226 egg-clusters, Eliot 27, York 182, Wells 47, 

 Kennebunk 9, Kennebunkport 3, making a total of 494 new 

 egg-clusters to date and 22 old ones. The scouting was con- 

 tinued to Biddeford, which was reached on January 28, 1907.
