BLACK-POLL WARBLER. -201 



in a given time, we separated. The more active scaled the most difficult 

 heights, and among them was our Captain, Mr Emeky, than whom a 

 more expert seaman and a better man is rarely to be found. Others 

 chose the next most difficult place of ascent ; while I and my young friend 

 Dr Shattuck of Boston, slowly moved along in quest of birds, plants, 

 and other objects. We soon reached a considerable elevation, from which 

 we beheld the broad Gulf of St Lawrence gathering its gray vapours, as 

 if about to cover itself with a mantle ; while now and then our eye was 

 suddenly attracted by the gliding movements of our distant parties, as 

 they slipped down the declivities. In this manner we had surveyed the 

 country for several miles, when the sea-fog began to approach the land so 

 swiftly, that, with the knowledge we all had acquired of the difficulty of 

 proceeding overland when surprised by it, we judged it prudent to return 

 to our vessel. There we compared notes, and made preparations for the 

 morrow. 



One fair morning, while several of us were scrambling through one 

 of the thickets of trees, scarcely waist-high, my youngest son chanced to 

 scare from her nest a female of the Black-poll Warbler. Reader, just 

 fancy how this raised my spirits. I felt as if the enormous expense of 

 our voyage had been refunded. " There,"" said I, " we are the first white 

 men who have seen such a nest." I peeped into it, saw that it contained 

 four eggs, and observed its little owner looking upon us with anxiety 

 and astonishment. It was placed about three feet from the ground, in 

 the fork of a small branch, close to the main stem of a fir tree. Its 

 diameter internally was two inches, the depth one and a half. Exter- 

 nally it resembled the nest of the White-crowned Sparrow, being formed 

 of green and white moss and lichens, intermixed with coarse dried grass ; 

 within this was a layer of bent grass, and the lining was of very dark- 

 coloured dry moss, looking precisely like horse-hair, arranged in a circu- 

 lar direction with great care. Lastly, there was a thick bed of large soft 

 feathers, some of which were from Ducks, but most of them from the 

 WiUow Grouse. 



I must now return to the United States, and trace the progress of our 

 Warbler. It enters Louisiana as early as the middle of February. At 

 this time it is seen gleaning food among the taller branches of the wil- 

 lows, maples, and other trees that overhang the rivers and lakes. Its mi- 

 grations eastward follow the advance of the season, and I have not been 

 able to comprehend why it is never seen in the maritime parts of South
