Expenditures for the control of the gipsy moth and brown-tail moth 

 in certain toivns and cities in Massachusetts. 



The foregoing figures indicate in a general way the ex- 

 penditures that are likely to be necessary in towns and cities 

 in uninfested States, in case the gipsy moth becomes estab- 

 lished. It shows conclusively the amount of protection 

 which other sections of the country are receiving as a result 

 of the gipsy-moth work which is being done in New Eng- 

 land. A large part of the funds expended by towns and 

 cities has been used for the protection of shade and orna- 

 mental trees, it having been found impossible to carry on 

 extensive work in woodlands, owing to the extreme cost of 

 these operations. 



The beauty and attractiveness of most cities and residen- 

 tial sections depend on the trees. These not only make the 

 region attractive and a desirable place to live, but also add 

 money value to the property. American cities are coming 

 more and more to realize the importance and value of shade 

 trees, and any step that can be taken for their protection 

 or to prevent injury from insects is most desirable. 



To prevent the introduction of serious pests into a region 

 where they are unknown is far more important than to ex- 

 pend large sums of money in an attempt to bring about their 

 control after they have been introduced and have success- 

 fully established themselves. This is precisely the work 

 which is being attempted in New England on the gipsy- 

 moth problem, and a record of expenditures from a few 

 localities which may be considered as average samples indi- 

 cates the benefit that other parts of the United States are 

 deriving from this important work.
