He has sprayed the trees on 26 acres of homesteads lying 

 between Main Street, Mystic Avenue and Hancock Street, to 

 destroy moths and elm-leaf beetles. He has sprayed a lot of 

 24 acres of woodland on Forest Street, and has treated the 

 gypsy moth egg clusters, to a distance of 15 feet from the 

 ground, on about one-half the trees. 



In the Middlesex Fells reservation he has sprayed about 327 

 acres of forest land, and has treated the egg clusters to the 15- 

 foot limit on the trees. 



He has sprayed 145 acres, mostly woodland, owned by the 

 city of Medford and bounded by Forest, Elm and Fulton streets 

 on the west and east and partly by Half Mile Eoad on the 

 north; and has thinned the trees and underbrush and removed 

 the dead limbs and dead trees thereon, cutting about 200 cords 

 of wood. He has treated the egg clusters to the 15-foot limit 

 on all the trees, and intends, if possible, to complete on them 

 this winter the destruction of both gypsy moth eggs and brown- 

 tail moth nests. 



The total number of acres of land cared for by General 

 Lawrence in 1906 was 1,441, or 2 1 / 4 square miles of seriously 

 infested territory.

 of illustrated lectures have been given by the superintendent and 

 by the agents, while the public lectures by Prof. W. L. Underwood 

 of Belmont and the Hon. C. O. Bailey of ISTewbury have been 

 most helpful. Our Bulletin No. 1, which gave in concise form

 new illustrations and additional matter in an edition of 10,000, 

 of which a large part has been distributed. Posters, briefly in- 

 structing property owners how best to fight the moths, were
