Mass.
Concord.- The widespread &, to the north of us, destructive
thunder storm of last evening brought the temperature
down over twenty degrees and to-day the weather has been delightful,
cool, with air of crystal clearness and a light N. to
N.E. breeze.
  The birds have responded promptly to the changed
conditions and this morning, as I paddled down
river to Ball's Hill, and again at evening, on my
return, I heard all the birds which breed along this
stretch of river except the Brown Thrasher, Savanna
Sparrow and Bittern. I am inclined to think that
the Thrashers have about ceased singing for my birds
at & near Ball's Hill were also silent. I have not
heard the Grosbeaks for several days until this
morning when they were in full song again. The
Purple Finch has been silent for a still longer
period but one was singing freely this evening.
The Meadow Larks have not sung much for
a week or more but I hear their plaintive
whistle a few times each morning & again at
evening.

  A few days ago I noted the apparent absence of
Orioles this season along the river below the town.
Up to that date there actually were none along this
stretch of river but the very next day I heard
one near Dalkin's Hill and they have since
steadily increased in numbers until to-day I
must have seen or heard at least half a dozen.

  Bronzed Grackles have also become constant
visitors to this part of the river much to
the wrath & dismay of the Red-wings whose
