Mass.
Concord. - sometimes used for brackets. He hung back
down and worked at the under sides cutting
and prizing out large pieces and frequently extracting
& eating something which we could not see through
our glasses even, although we stood directly beneath him.
  Faxon had a bad headache so we returned & spent
the forenoon about the house. At 1 P.M. rowed to
Davis's hill where we lay under the shade of a
big pine for nearly two hours. A large flock of
migrating Warblers drifted along past us under
shelter of the hill and then worked back again.
They were chiefly Yellow-rumps, Canadian Warblers,
Redstarts and Parulas. There was one fine male
Black-throated Blue Warbler which seemed curious
about us flitting back & forth in the bushes within
ten or twelve feet of us. There was also a Humming-
bird and I thought I heard a Blackburnian Warbler.
Martins soared high over the pines and a pair of
Carolina Doves flew past. We also saw a female Marsh
Hawk and later, as we were rowing back, two females
of this species hunting in company.

  Faxon left me at 3 P.M. but I decided to
spend another night in the cabin. After tea
I took a walk through my swamp & over the
pine hill beyond. Two Carolina Doves cooing, Oven-
birds going up continually. Veeries singing. A
Carolina Rail in Holden's meadow. The same frogs
& toads as last night.
  At 9.15 P.M. a Great Horned Owl began hooting in
the pines on Ball's Hill. The sound seemed to come
directly through the logs of my cabin as I sat inside.
