Concord, Mass.
Ball's Hill.
1900
August 27
  Clear, hot & very sultry with little or no wind.
  Left Jaffrey at 7 A.M. & for the last time this 
summer. Reached Concord at 9 A.M. Met Gilbert at
Tuttle's stable. He had driven down "Sylvia", the horse I
had been using this summer. We kept on to the farm
and Ball's Hill together.
  I spent most of the day near the cabin. There seemed
to be a good many birds about. On the way down from
Concord I saw flocks of Robins & Chippies, several Bluebirds
& Kingbirds, a fine adult male Oriole & two Phoebes. Near the
cabin I saw another Oriole also an adult male and heard
a Red-eye scolding. In the early afternoon a Mniotilta
sang five or six times in succession giving the short, wiry
spring notes. There was also a Wood Pewee singing as well.
At evening as I was walking over Pine Ridge an
Oven bird rose high in air & uttered its flight song
with full vigor. I also heard two Cat birds & two
Wilson's Thrushes and saw a number of Robins
assembling to roost in the pines behind Ball's Hill.
Small birds 
  Over the meadows just before sunset I heard
Bobolinks pinking but they were much less numerous 
apparently than during my last visit here. I also
saw a flock of a dozen Martins pass, flying
southward & heard Eave Swallows. There were no 
Red wings.
