THE SPRUCE BUD-WORM. 833 
ing worms" (probably like those observed by Mr. Alexander at Harps- 
well). The trees thus defoliated leaved out, becoming green again ; and 
in 1880 and 1881 the evil seemed to be diminishing, as has been noticed 
at other places. 
Further facts regarding the extent of the ravages of the spruce bud-worm 
in Maine. — The following facts regarding the extent of the ravages of 
this caterpillar on the coast of Maine were gathered during the summer 
of 1883, and for want of space omitted from the report published in that 
of the Entomologist of the Department of Agriculture. 
The westernmost locality at which the spruce bud- worm was observed 
was on Peak's and other islands in Portland Harbor, the spruce not 
extending in any great quantity west of that city. The spruces about 
Sebago Lake were also destroyed by this worm or a similar caterpillar, 
in 1878, as we are informed by Rev. Mr. Kellogg, a Mr. Townsend be- 
ing his authority. Around the shores of Casco Bay and on many of 
the islands, especially Birch Island, Orr's Island, Jewell's Island, and 
Great or Harpswell Island, also on Harpsweli Neck, Mere Point, Prince's 
Point, as well as other peninsulas extending into Casco Bay, wherever 
the spruces and firs grow thickly, extensive areas of these trees were 
observed ; also similar masses of dead spruce were observed along the 
Maine Central Railroad, from Portland to Brunswick, and thence to 
Bath ; also on the shores of Cathance River, at and near Bowdoinham, 
Me. Wherever the fiords or narrow bays and reaches extend inland, 
in Cumberland and Sagadahock as well as Lincoln Counties, the spruce 
and fir forests clothing their shores had been invaded by this destruc- 
tive caterpillar. Wherever the spruces were abundant on the Kenne- 
bec River, below Bath, particularly on the eastern side, at and near 
Parker's Point, and also at and west of Fort Popham, there were ex- 
tensive patches of dead spruces. Similar but smaller masses of dead 
spruce were observed along the steamer route from Bath to Boothbay 
Harbor, at and to the eastward of Southport ; none were observed on 
Mouse or Squirrel Islands. In the course of a journey, at the end of 
July, from Brunswick along the coast to Eastport, we were able to ascer- 
tain the eastern limits of the ravages of this worm. Several clumps of 
spruces which had just died were seen on the Knox and Lincoln Railroad 
before reaching the Wiscasset Station. At Waldoboro, southeast from 
the station, was an extensive area of dead spruces which presented the 
same characteristic appearance as in Cumberland County, and for two 
or three miles beyond Waldoboro there were to be seen large masses of 
dead spruces and firs. Beyond Warren no dead spruces were to be seen j 
none were observed about Rockland, Camden, Blue Hill, or the islands 
of Penobscot Bay ; none on Mount Desert, or on the islands from Mount 
Desert to East Machias, nor on the road from East Machias to Lubec, 
although the predominant growth is spruce. No dead spruces were to 
be seen about Eastport, nor along the St. Croix River, to Calais, and 
none along the railroad from St. Stephen's to Vanceborough and thence
