Concord, Massachusetts.
Mass.
Concord.- the period of general bird singing to that
of the insects. Of course there have been crickets for
two months or more and a few grasshoppers for
several weeks but they have not made themselves
really conspicuous, vocally (or rather instrumentally),
before this evening. I have heard the Tree Crickets
tuning their instruments for nearly a week past.

  The Chipping Sparrow with the split song continues
to sing the day through in the apple tree by the
river. He sits usually on the same branch facing the
same way and seem to be wholly indifferent to
conditions of heat or cold.

  This evening I saw a pair of Chippies in coitu
on the ground in the middle of the wood. This
would indicate very late nesting.

[margin]July 31[/margin] Sunday.- Still cooler with east wind and a
heavy rain-storm from 10 A.M. to 6 P.M.
[margin]Up Assabet[/margin]
    Spent most of the day in the house but
at 3 P.M. started up river with Forbush in
the canoes. We have intended to camp for the
night at Fairhaven but the weather changed our
plans and we merely paddled up the Assabet
for a mile or so and then back and up the
Sudbury to Nashawtuck bridge where F. left me
and walked to the station to take the train.
  It was raining very hard during all the
time we were out & we saw few birds;–two Spotted
Sandpipers, a Bittern, and about 100 Swallows, with
a few Red-wings & Bobolinks & a flock of Grackles.
