Lake Umbagog.
Pine Point.
1898.
September 9
  Similar to yesterday but with less wind. Early morning
densely foggy.
  Only a few Warblers migrating last night, although the
conditions seemed favorable, and scarce half-a-dozen seen

Black-throated Blue, Yellow-rumps and Black throated
Green Warblers. One of the last sang freely as did a 
Red-eyed Vireo.

or Grosbeak in the distance. The bird approached rapidly
and circled low over the Point as I could tell by
the distance and distribution of its notes. Finally it alighted

I had not been able to make up my mind whether
the bird was a Thrush or Grosbeak; the night calls of 
the two are really almost indistinguishable I fear.
  When I first looked out from the tent at about
half-past five the lake was densely shrouded in fog.
As I stand listening to the cry of a Loon some
waves rolling out from the shore attracted my attention
to a file of Sheldrakes that were passing within twenty
yards of one close in under the rocks. I counted
six of them. A few moments later I saw them
crossing the mouth of the boat cove, cleaving deep
furrows in the glassy surface. I could trace wash
furrow to its apex after the grayish colored bird that
