During most of the afternoon a number of Barn Swallows 
were flying about over Mr. Keyes’s field, coursing close over 
the stubble like hounds searching for a lost trail. It is one 
of the prettiest sights which the summer brings-ghese graceful 
long-winged, fork-tailed birds skimming swiftly to and fro 
turning and returning abruptly and seldom leaving £he bounda- 
ries of the field. It carried my thoifhts back to boyhood and 
to England. 
Fully 100 Barn Swallows were flying over the meadows op- 
posite Ball's Hill this forenoon. I reviewed a large portion 
of the flock without detecting any other species except the 
Eave Swallow of which I saw a single representation.
