THE HACKMATACK OR LARCH SAW-FLY. 29 



J 11 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 thai they were suf- 

 ficient to cause the death en masse of these trees. In L#83 we visited the 



locality, and many of the trees had been cut down for- fuel. 



From Rev. Mr. Kellogg we learned the following interesting fact 

 garding the appearance of a similar, most probably the same, species of 

 caterpillar, even upon the same farm that was ravaged in L878, early 

 in this century. According to Capt. James Sinnett and Mr. John Jor- 

 dan, of Harpswell, the spruces of Harps well and Orr's Islands were de- 

 stroyed in 1807. Captain Bishops, whose son made 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 187.S ap- 

 peared on the same farm ou which the spruces had been destroyed bv 

 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 (JRTematus erichsonii f) begins to deposit its eggs at Brunswick 

 about the 20th of June. During a journey to the Eangeley Lakes and 

 the White Mountains this saw fly 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 toUmbagog. 

 It was also observed depositing eggs in trees at Errol, J. EL: and 

 along the route from Errol to Berlin, X. 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. 



Early 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 1 )anvers, .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 ]S T ematus larva ; sonic 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 

 westofthe Kennebec River. It appears, tlien, that throughout the State
