that more will be in the field before the opening of the cater- 

 pillar season, thus giving us a better chance to check the moths 

 in these localities. In the generally infested section it will be 

 well to keep a close watch on the woodlands, that the infesta- 

 tion there may not become serious, thus saving the costly work 

 under such conditions, which several of our cities and towns 

 have been obliged to undertake. In the slightly infested locali- 

 ties the work should have extermination in view at all times, 

 and, if -possible, all small infestations should be stamped out. 

 It is also very necessary that the snow-line cleaning should be 

 carried on as in the past, as it relieves all engaged in the work 

 of much anxiety, if we are fortunate enough to have a large 

 amount of snow during the winter months. It is also necessary, 

 where funds will permit, to carry on as extensively as possible 

 the tin patching and cementing of cavities in infested orchards, 

 and also the removal of decayed trees. There is no other method 

 of work that will assist us so much in putting our colonies into 

 good condition in the residential sections as this work. 



Speciax Work in Paeks. 



During the year 1908, as in 1907, this office has, with the 

 approval of His Excellency the Governor, deemed it wise to 

 give assistance to several municipalities in which were located 

 badly infested parks, and where the cost of clearing would be 

 more of a financial burden than the city or town could stand. 

 The following places were given consideration: Pine Banks 

 Park, Maiden and Melrose; Prospect HiU Park, Waltham; 

 Lynn Woods, city of Lynn; Shaker Glen, Woburn; Mt. Ann 

 Park, Gloucester. 



In Pine Banks Park it was necessary to do a considerable 

 amount of thinning, and the greater part of the egg clus- 

 ters ivere treated. This was done with the understanding 

 that the trees would be sprayed by the cities of Maiden and 

 Melrose, but when the time arrived it was impossible to get 

 them to do this work. We were fortunate enough, however, 

 to have the assistance of the United States government, and the 

 larger part of the park was sprayed by them. During the fall 

 more thinning was done, and the park at the present time is
