In its journey northward in spring- to its summer home the greater 

 number of Black-poll Warblers choose an eastern route, and throughout 

 the Eastern Province it is one of the most abundant of the transitory visit- 

 ants, passing through in an almost continuous stream from the 20th of May 

 till the 1st of June. It has recently been ascertained to occur in Kansas 

 by Mr. F. H. Snow, as quoted above. Near Denver, in 1873, it made its 

 appearance a few days earlier than it is wont to do in New England, and 

 by May 17 both sexes were abundant, and passing rapidly onward. Tliis 

 is, I believe, the most western locality at which the species has been 

 recorded.
