Mass.
Concord.- Occasionally a Bat darted past within a
few feet or even inches of my head and was almost
instantly lost to sight in the gloom. Fireflies in
small numbers flashed their tiny lights along the
edges of hazel copses or in and out among the foliage
of the oaks. The only sounds now were those of the Mice
among the leaves, the fine shrill squeaking of Bats,
the feeble chirping of summer crickets and now & then
the notes of a distant Whippoorwill. Some Green Frogs
were tung ing in Rhodora Pool but the calling season
of the Tree Toads is over - I have not heard one for
a week or more.

  My experiences with the Whippoorwills to-night taught
me some new things about them. As I stood on
the knoll in the Eastabrook road two came close about
me uttering an emphatic note [delete]call[/delete] which, within a distance
of 20 or 30 yds., sounded like quoip, & further off, was
distinctly quip. This was apparently a call note
used by both sexes for these birds were almost certainly
a pair. They [delete]made sang [?][/delete] moved their positions
frequently as I could tell by their calls apparently
taking short flights from place to place among the
sprouts but never once showing themselves against
the light in the western sky. The male sang every
few minutes, often very near me. As a rule he uttered
the quip or quoip from one to five times in quick
succession just before the song began but this was
not invariably the case. I heard the well-known
clucking call whenever the bird was within 50 or 60
yards. It resembles most closely the cluck of the
