among the Franconias about the summer of 1886, and Dr. J. A. 

 Allen (Faxon & Allen, '88) records them at Bethleham and 

 Franconia in 1874, though apparently the bird is now very rare 

 or wholly absent from these regions in summer. I have never 

 seen it about Intervale save in fall, although there seems to be 

 suitable country for it. On September n, 1899, I noted two in 

 some bushes on the Saco meadows at Intervale, but have never 

 seen others there. In the Connecticut valley the bird is fairly 

 common at least as far up as Lancaster, where both Mr. F. B. 

 Spaulding and Mr. H. W. Wright have found it in summer, 

 and the latter gentleman observed a single bird singing in the 

 western part of Jefferson on Aug. 12, 1901. A few also work 

 up the side valleys farther south to some distance ; thus Mr. G. 

 H. Thayer has found it in Marlboro commonly, while farther 

 up at Dublin it is rare. 



Dates: May 9 to September n. 



213. Dendroica cserulescens (Gmel.). Black-throat- 

 ed Blue Warbler. 



A fairly common summer resident of the rich, sub- Canadian 

 woods, inhabiting the denser undergrowth along the forest 

 brooks. Dr. W. H. Fox writes me that it breeds rarely at 

 Hollis on our southeastern border, and Mr. G. H. Thayer finds 

 it about Monadnock rather commonly. In central New Hamp- 

 shire it is fairly common locally. Among the White Mountains 

 it occurs commonly up to the 3,000 foot limit, above which I 

 have rarely found it. On June 21, 1900, I observed a single 

 male singing by the lake in Carter Notch at the altitude of 3,360 

 feet. The males continue to sing at intervals long after the 

 breeding season, and I have heard their song in the woods at 

 Intervale until the 17th of September. 



Dates : May 10 to October 10. 



214. Dendroica coronata (Linn.). Myrtle Warhlkr. 



A very common spring and fall migrant, and a common 

 summer resident of the Canadian fauna. It breeds rather spar- 

 ingly in coniferous growth on the hills of the southwestern part 

 of the state and along the height of land which bounds the Con-
