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 hud-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 ol:' 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 Harpswell 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 Eailroad, from Portland to Brunswick, and thence to 

 Bath ; also on the shores of Cathance Eiver, 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 Kiver, below Bath, particularly on the eastern side, at and near 

 Parker's Point, and also at and west of Fort Po{)ham, 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 Eailroad 

 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 ; 

 none were observed about Eockland, 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 Eiver, to Calais, and 

 none along the railroad from St. Stephen's to Vanceborough and thence
