54 FIELD WORK AGAINST GIPSY AND BROWN-TAIL MOTHS. 



in an attempt to determine the extent of the infestation and to pre- 

 vent the spread of the pests from colonies along the highways. For 

 three years the greater part of this territory has been inspected in a 

 similar manner. 



During the summer thousands of people from all sections of the 

 country visit the State, which is noted for its summer resorts and 

 mountain scenery, and this has been a potent factor in dispersing this 

 insect. Many automobile parties tour the State, and not infre- 

 quently trips are made from Boston and vicinity to the White 

 Mountains and lake resorts. During the time the gipsy moth was 

 allowed to develop without interference in Massachusetts, excellent 

 facilities were offered for its dispersion throughout New Hampshire. 

 Travel is unusually heavy at the opening of the vacation season, 

 which is the time when the larvse are small and most easily carried. 



The scouting operations have resulted in locating many colonies in 

 and around summer camps and country houses frequented by vaca- 

 tionists who come from badly infested districts in Massachusetts. 



The most serious feature of the problem in New Hampshire is the 

 undoubted infestation of a large part of the thickly wooded area in the 

 southern part of the State. Remedial measures are entirely imprac- 

 ticable, as it is impossible to apply them to such large areas of low- 

 priced forests, owing to the great expense involved. 



The greater part of the area is not yet badly infested, but unless 

 the people of the State become aroused and exert themselves to 

 check the gipsy moth serious injury will be caused to the trees and 

 enormous loss is bound to result. 



In the residential sections the people will, when the moth increases 

 to an extent to cause serious injury, undoubtedly awake to the situa- 

 tion, and exert themselves to preserve their trees. 



The brown-tail moth has been found in an area covering over one- 

 half of the State, and in the entire section east of the Connecticut 

 River watershed and south of Lake Winnepesaukee it is most abun- 

 dant and is causing great damage. Its presence has caused much 

 complaint from residents and summer visitors, and this has led to 

 effective work being done along the roadways and in some of the 

 towns. Colonel Dearborn has succeeded in awakening considerable 

 interest in this work in certain sections of the State, and some relief 

 from this troublesome pest has been secured where it has been pos- 

 sible to sufficiently arouse public sentiment. 



The State has spent $37,500 and the Bureau of Entomology about 

 $90,000 in the work in New Hampshire.

The presence of the gipsy moth in Providence was discovered in 

 1901, and some effort was made by the city and property owners to
