GIPSY MOTH WOBK IN NEW ENGLAND. 25 



efficiency, the careless and negligent men being dropped from the 

 rolls. When large colonies are found crews of woodchoppers are 

 employed temporarily to cut out the worthless trees and clean up the 

 undergrowth in order to render the area in condition for effective 

 operations. 



The accompanying map (PI. X) shows the territory which was. 

 known to be infested by the gipsy moth in the fall of 1913. In organ- 

 izing the work a large party of scouts was sent to Maine for the pur- 

 pose of determining whether the infestation had spread beyond this 

 line. The results of the examination show that a large number of 

 towns are infested outside the border previously established. The 

 work was continued until late in December, when it was necessary to 

 transfer the men on account of deep snow and extremely cold weather, 

 the temperature for a number of days being as low as 20° to 25 a 

 below zero. In all, 155 towns were scouted in Maine, and of these 81 

 were found infested. The increase in the number of towns over that 

 of previous years is largely explained by the fact that during the 

 winter of 1912-13 the scouting work was not completed on account, 

 of snow and also because of the undoubted dissemination of the moth 

 by means of the spread of the small caterpillars by the wind. The 

 manner of this kind of spread has already been explained in this 

 report. Suffice it to say, the general trend of dispersion of this insect 

 has been toward the north and northeast on account of the fact that 

 the prevailing warm winds during the time the caterpillars are 

 hatching blow from the south and southwesterly directions. The work 

 was continued from January until April in New Hampshire, Massa- 

 chusetts, Rhode Island, and Connecticut. 



On February 3, 1914, a report was received that several gipsy-moth 

 egg clusters had been found on an estate at Bratenahl, Ohio, a suburb 

 of Cleveland. The matter was at once investigated and two experi- 

 enced scouts were detailed to make an examination of the estate and 

 the surroundings. At the time the work was done there was con- 

 siderable snow i on the ground, making inspection work difficult. 

 Seven new egg clusters were found and treated and later in the season 

 the colony was burlapped and the trees sprayed. The work in Ohio 

 was done in close cooperation with the Ohio Agricultural Commis- 

 sion, and work in the colony since the original scouting was done has 

 been carried on by the assistants of Mr. N. E. Shaw, State nursery and 

 orchard inspector. 



On May 7, 1914, a report was received from Mr. George G. Atwood, 

 chief of the division of horticulture of the State of New York, that a 

 gipsy-moth colony had been found at North Castle, Westchester 

 County, N. Y. Inspectors from this office were detailed to treat egg 

 clusters, and several experienced scouts were transferred to assist in 

 stamping out this colony. The principal infestation occurred on a 

 large estate, and the caterpillars began hatching soon after the first
