INSECT ENEMIES OF THE SPRUCE IN THE 



NORTHEAST. 



OUTLINE OF TRIP. 



On May 22, 1900, I arrived at Brunswick, Me., where I learned that 

 Mr. Austin Cary, of that place, had gone with a surveying party to 

 near the head of the Androscoggin River, and that, owing to floods 

 and log jams on the upper streams, some trouble would be experi- 

 enced in getting through to where he was located. This necessitated 

 a delay of two days, but in the meantime arrangements were made 

 by Mr. H. J. Brown, of the Berlin Mills Company, for transportation 

 and guides from the railroad at Colebrook, N. II., until we found Mr. 

 Cary. 



May 24 I left Portland going northwest through New Hampshire via 

 the White Mountain Notch to Colebrook. Here I was met by two 

 guides sent over from Erral with instructions from the Berlin Mills 

 Company, and on May 25 we left Colebrook, going up the Mohawk 

 River valley and through the Dixville Notch near its source, thence 

 down Clear Stream to Erral on the Androscoggin. Here we encoun- 

 tered the floods and log jams which prevented further progress by 

 wagon, and the remaining distance to the Brown farm in Maine was 

 traversed on foot and by canoe. 



May 26, after spending a few hours in the woods studying insect 

 enemies of the spruce, larch, and fir, we went on up the Magallowaj^ 

 River about 15 miles to the Camp in the Meadows where we were met 

 by Mr. Cary. The next morning we proceeded farther up the river 

 to the Forks Camp near the mouth of the Little Magalloway. This 

 brought us into the heart of the northwestern Maine woods and within 

 a few miles of one of the localities in which the spruce were dying. 



Up to this time the route from Portland through New Hampshire 

 and a small part of Vermont to Colebrook, thence across northern 

 New Hampshire and up the Magalloway in northwestern Maine, led 

 through a region presenting many and varied features of New Eng- 

 land forest conditions, and gave a good opportunity to note in a gen- 

 eral way some of the influences which contribute to the multiplication 

 of insect enemies of trees, as well' as those which contribute to their 

 decrease, or even the extermination of certain species which confine 

 their attack to matured timber. No opportunity was had, however,
