THE HACKMATACK OR LARCH SAW-ELY. 29 
In addition to the facts regarding the great abundance of the bud- 
worm we may cite information given us by Prof. L. A. Lee, of Bowdoin 
College, who observed the bud-worms in June, 1880, upon the spruces 
at Prince’s Point, Brunswick, and had no doubt but that they were suf- 
ficient to cause the death en masse of these trees. In 1885 we visited the 
locality, and many of the trees had been cut down for fuel. ' 
From Rev. Mr. Kellogg we learned the following interesting facts re- 
garding the appearance of a similar, most probably the same, species of 
caterpillar, even upon the same farm that was ravaged in 1878, early 
in this century. According to Capt. James Sinnett and Mr. John Jor- 
dan, of Harpswell, the spruces of Harpswell and Orr’s Islands were de- 
stroyed in 1807. Captain Bishops, whose som madé the statement to 
Mr. Kellogg, cut down the dead spruces on these islands and worked 
six weeks boiling the sea-water with fuel thus obtained, in order to make 
salt. This was during the embargo which lead to the war of 1812 with 
Great Britain. It is interesting to note that the bud-worm in 1878 ap- 
peared on the same farm on which the spruces had been destroyed by 
a worm in 1807, or about eighty years previous. 
FURTHER DATA REGARDING THE HACKMATACK OR LARCH WORM. 
The following facts were gathered during the summer of 1883 in Maine 
and New Hampshire, and other points in New England and New York, 
and are here put on permanent record. 
We have already stated in the Entomologist’s report that the larch 
saw-fly (Nematus erichsonii?) begins to deposit its eggs at Brunswick 
about the 20th of June. During a journey to the Rangeley Lakes and 
the White Mountains thissaw-fiy was observed depositing its eggs, July 
1, at Phillips, where it was observed to be abundant. It was also ob- 
served on the 2d at the Mountain View House, Rangeley Lake; also on 
the larches along the Five-Mile Carry from the Middle Dam to Umbagog. 
It was also observed depositing eggs in trees at Errol, N. H.; and 
along the route from Errol to Berlin, N. H., it was observed at work 
July 4, while a number of dead trees were noticed which had died 
from the effects of their attacks during the preceding season. We 
learned that they had been destructive last year in Cambridge, N. H. 
Karly in July these worms were also observed by us on the European 
larch in Lawrence, Mass., and they were abundant on the European 
larch on the grounds of Andrew Nichols, esq., of Danvers, Mass. July 
16, the larches along the track of the Eastern Railroad from Saco to 
Portland were observed to be brown, having been partly defoliated by 
the Nematus larva; some of the trees were almost entirely stripped. 
During the last week in July we went from Brunswick to Rockland, 
and thence along the coast to Eastport, returning to Brunswick by way 
of Calais and Bangor. The larch is a very common tree in the eastern 
portion of Maine, especially along the coast, on the islands, and in the 
northeastern and northern part of the State. It is comparatively rare 
west of the Kennebec River. It appears, then, that throughout the State
