INSECT ENEMIES OF THE SPRUCE IN THE 



NORTHEAST. 



OUTLINE OF TRIP. 



On May 23, 1000, I arrived at IJi-nnswiok, Me., wliere T learned that 

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

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

 and log jams on the up])er stieanis, some trouble would be expei'i- 

 enced in getting through to where he was located. 'J^'his necessitated 

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

 by Mr. II. J. Brown, of the Berlin Mills Company, foi' transportation 

 and guides from the i*aili'oad 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 Ei'ral 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 Eri-al on the Androscoggin. Here we encoun- 

 tered the floods and log jams which prevented further progress by 

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

 traversed on foot and by canoe. 



Maj^ 2G, after spending a few hours in the woods studying insect 

 enemies of the spruce, larch, and fir, we went on up the ]\Iagalloway 

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

 by Mr. Cary. The next moi-ning 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 wei-e 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 northwesteiii Maine, led 

 through a region i:»resenting many and varied featui-es of New Eng- 

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

 eral way some of the influences which contribute fotlu^ multiplicaHon 

 of insect enemies of trees, as well as those wiiicli cont ril)ut(' to their 

 deo'ease, or even the extermination of cei-lain species which coTifine 

 thcMr aftack to matui'ed limlxT. No oi)port unity was had, however,
