brush in the infested woodland adjoining the park was cut, 

 the trees thinned, burlapped and thoroughly attended during the 

 summer. The result of the fall examination shows that the 

 numbers of the moths have been greatly reduced. 



At the present writing the street trees have been cleared of 

 the moths, and a large amount of roadside trimming and brush 

 cutting has been done. In connection with the work of clearing 

 private estates this winter, worthless hollow trees will be re- 

 moved and the cavities in those remaining cemented or closed 

 with tin. 



HANOVER. 

 W. S. STODDARD, Local Supcrinti ndcnt. 



In the town of Hanover, where the problem of the gypsy 

 moth in orchards reaches great importance, there were killed 

 last summer about 17,000 gypsy moth caterpillars. Seven thou- 

 sand yards of burlap were put on trees by the local superintend- 

 ent, and were well attended, as the above figure shows. 



Following the larval season over 2,400 egg clusters of the 

 gypsy moth were destroyed, 500 of these being on two pasture 

 oaks. In the fall of 1906, 90 estates in Hanover were known 

 to be infested with the gypsy moth; and since May 1, 1907, 66 

 additional infestations have been locate <!. 



There "are a number of badly infested localities, due mostly 

 to the existence therein of hollow, worthless old apple trees. 

 Operations against the gypsy moth in the town have been 

 pushed with very great energy by the local superintendent. 

 Under his direction infested walls have been worked over, and 

 eggs, larvae or pupa? hidden under the stones destroyed ; while 

 many trees have been either cut or trimmed, scraped, burned 

 out and cemented. Much orchard work yet remains to be done, 

 for the number of worthless or neglected trees is still great, and 

 these are a distinct hindrance to the work against the gypsy 

 moth. A continuance of the energetic orchard campaign in 

 1908 should show a great advance in the work of suppressing 

 the gypsy moth in Hanover next fall. 



The fall scouting of the town did not develop serious woodland 

 conditions. The known gypsy moth infestations are not many 

 or in bad shape to handle ; but the woodland area between
