Penobscot Bay, Maine.
1896 
July 10                                                             
  Forenoon foggy; afternoon clear over the land but with damp fog hanging
down then Bay despite a strong S. W. wind.
  We did not go out at all to-day. I spent this morning in the
house writing etc., this afternoon rambling about the woods on the
point & cutting away the small spruces around two large boulders
which I intend to photograph later. Most of the smaller wood
birds singing freely all day, especially during the forenoon when
the woods were enveloped in fog. I have noticed before that the
densest fogs seem to stimulate rather than depress the spirits of
birds which dwell along our coasts. It is quite the contrary
at Lake Umbagog where, even at the height of the building season,
the birds rarely sing at all until the morning fogs begin to break
or burn away.
