  Returned to Concord by the 5:01 P.M. train.
  On reaching the cabin I found two Lincoln's Finches,
a White-crowned Sparrow, 2 Swamp Sparrows, a
Song Sparrow & a White-throated Sparrow busy 
at the seed bed. Gilbert says that there were
two White-crowns that came in the day &
that he saw a third at Concord this forenoon.

  Taking a run over & around the Hill just
before sunset I found Warblers very numerous.
I saw a fine male Blackburnian, a Black-throated
Blue, a Wilson's Black-cap, 8 or 10 Yellow rumps,
a pair of Chestnut-sided, 2 or 3 Creeper, and
numbers of Redstarts & Oven birds.

  Forty or fifty Barn Swallows, eight or ten
Eave Swallows & perhaps a dozen Swifts were
darting about in noisy lines just above
the tops of the large oaks which crown the
summit of the Hill.

  Vireos were calling in all directions at
sunset but I heard none sing.
