THE GIPSY MOTH IN NEW HAMPSHIRE. 229 



until every locality in the state is definitely known. The 

 destruction of isolated colonies will also be undertaken, but 

 the state should make provision for a certain proportion of 

 the work and should adopt a law similar to the law now in 

 force in the state of Massachusetts in order that exter- 

 minative work may properly be enforced and in order that 

 the state may not be left defenseless should the appropri- 

 ations by the general government be insufficient in the 

 future as at present to handle the whole case, or should they 

 lapse entirely. A law based upon that of Massachusetts 

 will also enable New Hampshire to handle the brown-tail 

 moth question, and, as explained in various publications 

 of the bureau of entomology of the United States depart- 

 ment of agriculture, the government campaign against this 

 latter insect can at no time assume much more than educa- 

 tional proportions, since the actual prevention of the spread 

 of this insect into new territory now seems not to be feasible. 



Cost of Work Against the Gipsy Moth. 



As the result of a very considerable experience, ]\Ir. 

 Hogers estimates the cost of work against the gipsy moth 

 in a general way about as follows : 



For preliminary scouting work from $100 to $150 per 

 town; for effective work like fall and winter cleaning, cut- 

 ting the brush and worthless trees, putting on burlaps and 

 attending them for two months, he estimates at about $1,000 

 per town; while the more exacting work, looking towards 

 extermination, which would require a careful inspection 

 after the cleaning, spraying in some of the bad places, 

 <?ementing and tinning holes in trees, and following all 

 phases of the work every month in the year, he estimates at 

 about $2,000 per town. 



The details of the expenses of the moth work may be esti- 

 mated about as follows, basing them upon a cost of $2 per 

 day of eight hours for each laborer, 10 to 12 cents per 

 pound for arsenate of lead, and one and one-half cents per 

 yard for 8-inch burlap :
