Ball's Hill
&
Farm
  To Concord by 8.34 train, crossing the river
at West Bedford, spending the remainder of the forenoon
at Ball's Hill, driving to the farm after dinner and
walking back through the woods by way of Pulpit Rock,
the Spring and Davis's Swamp in the late afternoon, 
strolling to Bensen's landing and Pine after supper.
  At Ball's Hill I heard the usual birds in about
the usual numbers - Robins, Vireos, Creepers, Ovenbirds,
Redstarts, a Grosbeak, Chestnut sided Warblers, Song &
Swamp sparrows, a Wood Pewee, King Birds, Red wings etc.
Birds noted 
at
Ball's Hill
  A Wood Thrush was in full song among the oaks just
behind the cabin at 5 P.M. and two hours later
I heard what was doubtless the same bird at
Bensen's landing. On this second occasion I saw the
bird perched on a branch of a large oak at least
40 feet above the ground. Every time he sang he opened
his wings and beat them with a rapid, quivering motion
closing them again at the end of each bar. He was a
fine singer with a strong, clear voice. I have never
found a Wood Thrush at Ball's Hill before excepting 
during migration.

Singing at
the cabin 
  There were four or five Vireos singing in the
immediate neighborhood of Ball's Hill including the
Blakemore glen & swamp.
  Two Bitterns were pumping at sunset, one
directly opposite the cabin, the other in the South cove
of Great Meadow.

  A Grass Finch was singing in Pine Park.
