38 GYPSY AND BROWN-TAIL MOTHS. [Jan. 



orchards. A thorough cleaning was given the town in the 

 early part of the year. This was followed by excellent work in 

 burlapping and spraying. During the fall months, brush cut- 

 ting along roadsides, cementing and tinning of cavities in badly 

 infested orchards and the destruction of the nests or webs of 

 the moths, occupied the attention of the local force. At the 

 present writing the cleaning of the street trees is in progress. 



An excellent showing has been made in this town, consider- 

 ing the amount of money expended. The purchase of a power 

 sprayer for the 1908 campaign would be highly desirable, par- 

 ticularly in view of the number and size of the woodland

CAMBRIDGE. 

 J. F. DONNELLY, Local Superintendent. 



Excellent results have been obtained from the work against 

 the moth in this city, due very largely to good management on 

 the part of the local superintendent. In the most seriously 

 infested sections burlaps were freely used, and -a considerable 

 amount of spraying was done during the caterpillar season. 

 The street trees, generally speaking, are in excellent condition 

 as regards the gypsy moth, and the same is true of many private 

 estates, so that the cost of the winter and spring work will be 

 much less. With the bulk of the gypsy moths practically wiped 

 out in Cambridge, more general use of burlap will be desirable 

 during the coming summer. Spraying operations will be re- 

 quired wherever the caterpillars are found in unusual numbers. 



Cambridge is particularly liable to reinfestation from outside 

 sources. Many thousands of persons annually visit the Harvard 

 College grounds, Mt. Auburn Cemetery, the Washington Elm 

 and other places of s]>ecial interest ; and the chances are highly 

 probable that a very large number of gypsy moth caterpillars 

 are annually brought into this city as unwilling passengers mi 

 the vehicles or persons of these visitors. This point is men- 

 tioned to emphasize the need of constant watchfulness, which 

 shall detect and suppn-s .-my incipient colonies that may be- 

 come established.
