THE BLACK-POLL WOOD-WARBLER. 3X 



high or low over the sea. Of these the greater number were, like the pre- 

 sent species, Sylvise which are never found in Georgia or the two Carolinas. 

 Their course was a direct one, and such as led me to believe that the little 

 voyagers were bound for Cape Hatteras. The meeting with many of the 

 species to which I allude, along the shores of Maryland, New Jersey, the 

 eastern coast, of Long Island, &c, and all along to the Bay of Fundy, has 

 strengthened the idea; but as I may not be correct, I leave the matter to the 

 determination of more experienced observers. The subject appears to me to 

 be one of the greatest importance, for the occurrence of plants in certain 

 parts of a country and not in others may possibly be caused by the absence, 

 during migration, of such birds as move by "short cuts" from one point of 

 land to another.
