DELAWARE VALLEY ORNITHOLOGICAL CLUB. 23 



forest is almost all gone, largely Carolinian. This forest-cutting 

 began about 1840, and went on steadily until practically all the 

 marketable lumber was exhausted about 1880. So about Buck 

 Hill you find a few stragglers from the Canadian fauna, the 

 survivors of the old Alleghanian fauna and many intruders 

 from the Carolinian. The country was most interesting to me 

 ornithologically in that it gave me the chance to know better 

 three birds I had scarcely known at all, and of a charm that I 

 had not been led to expect — the Eave Swallow, the Louisiana 

 Water Thrush and the Blue-headed Vireo — the last, one of our 

 really notable American singers.
