(No. 2)
  Shortly after six o'clock I started to drive to
Ball's Hill. A Towhee was singing in the bushy hollow
just above Bensen's, a Grass Finch in Pine Park,
and a Tanager behind the wood shed. On
reaching Ball's Hill I heard two Yellow-billed Cuckoos
and several Red-eyed Vireos besides Red-wings and 
a Swamp Sparrow.
  After supper I walked along the river path to
the Barrett meadow and Holden's Hill. A great swarm
of Swallows were coursing about over the river and
meadows preparatory to going to roost. They passed
over or near me five or six times but I could not
ascertain where they finally settled. There must
have been fully 200 or 300 birds in the flock which,
judging by their cries, was largely made up of
Barn Swallows and Bank Swallows although I also
heard the voices of White-bellied and Eave Swallows.
  The Swifts were not in the chimney when we
reached the cabin but we heard them both come
in just before dark. The nest looks exactly as it 
did when we last saw it on the 15th. and I
do not think that any eggs have as yet been
laid in it.
  Bull Frogs are bellowing and Green Frogs ringing
as I write this at 9 P.M. but the Toads, thank
heaven, have apparently ceased their discordant
swawking for this season.
