1892.
April 25
Concord, Massachusetts.
Mass.
Concord. - A cold night followed by a warm, sunny day
with absolutely cloudless sky and light N.W. wind
  To Ash Swamp at 10.30 A.M. driving up with George
& sending the horse back by a stable boy.
  Spent the entire day digging spice bushes, hornbeams,
and yellow birches in the pasture on the northern
side of the swamp. A Robin and Song Sparrow the
only birds singing within hearing.
  At 5 P.M. started to walk home through the woods.
I have never, I think, seen the country more beautiful
at this season. The late afternoon light was wonderfully
pure and strong yet very soft & tender. The air was
perfectly still. Hylas peeping & Robins & Song Sparrows
singing. A loud squealing outcry in a maple copse
near the old orchard north of the swamp attracted my
attention to a [female] Hairy Woodpecker which was flying
from tree to tree. As I was passing through Hubbard
pasture I was startled by another and different
squeal, short, sharp & metallic. It came from under
a young pine within a rod of me & I heard something
jump in the dry leaves. The next instant a
Rabbit (L. sylvaticus) dashed out and bounded across
a space of open, hard, turfy ground thumping as it
ran. It will be remembered that I heard one
utter a precisely similar squeal near Ball's Hill
in the winter.

  I followed the Lime-kiln ridge south & then crossed
to the path through the "[?] lot." As I came
out into Pratt's pasture a Hermit Thrush began
singing among the Scotch pines. It uttered three or 
four bars and then ceased. I never heard a migrant
sing in Mass. before.
