in sight, either flying low and feeding om keeping on 
directly South at a height of 300 or 400 feet. All those 
which I saw after sunset were flying high and towards the 
South. There can be no doubt that what we witnessed was 
a veritable migration. 
Barn Swallows accompanied or appeared with the 
Swifts this evening, although not one had been seen during 
the day. There were not many —perhfo^s a dozen in all. 
They flew about in small clusters, scattering occasionally 
and feeding a little, but as a rule keeping close together 
and ragher high in air. They acted as if they were looking 
for a roosting place. 
There was also an unusually heavy and well-marked 
migration of Night Hawks, beginning at about 5 P. M. and 
lasting until nearly dark. They all came from the north¬ 
east in ones, twos, and threes and went off towards the 
south-west, a course they invariably follow here. While 
crossing the meadov/s they descended and fed for a few 
minutes by flying about in irregular lines, but none of 
them tarried long. Indeed, I have rarely seen them appear 
to be in greater haste to push on southward. We counted 
18 birds in all. 
As it was getting dark this evening I walked with 
Hr. Hubbard to Dakin* s Brook and back. Before the light 
had faded in the west, Y/arblers began lisping overheard 
and for the next hour it was impossible to listen intently
