Concord, Mass.
1900.
July 23
  Clear and hot with light S.W. wind.
  Left Jaffrey at 7 A.M. and reached Concord at 9 A.M.
Petersen met me at the station and drove me to the
farm where three adult male Towhees were singing within
my hearing at once. I also heard a Maryland Yellow throat
sing a few times & saw a Chipping in the orchard. These
were literally all the birds I noted at the farm.

at Farm
  When I reached Ball's Hill the woods seemed devoid 
of bird life but as the heat began to abate in the
late afternoon Swamp Sparrows & Red-wings sang
rather freely. Gilbert tells me that he heard a Robin
and a Red-eyed Vireo singing near the cabin this morning.
At sunset an immense flock of swallows collected
over Holden's meadow and swept back and forth, at first
rather high in air, finally low over the tall grass.
They acted as if they were going to roost in the
willows opposite Pad Island but I did not actually
trace them there. There must have been fully 500
birds in the flock, the majority evidently Barn Swallows
with a few Eaves & White-bellies.

  Bitterns were flying about all afternoon. At
evening I heard a Solitary Sandpiper calling over the river.

  At 8.30 P.M. a Fox barked many times in succession
across the river.

  Pat Flannery tells me that Mason Wheeler killed a
large Canada Porcupine last week near Bateman's Pond.
There were two together but one escaped. The one killed was
hung up in Davis's store for three days & was seen by 
many of the Concord people including Herbert Holden.
