August 8
  Cloudy with occasional light showers. Heavy rain all
through last night. Rather sultry with light S.W. wind.
  Spent the forenoon near the cabin. In the afternoon
walked to Pine Ridge & the Barrett meadow. After
supper strolled around behind Ball's Hill.
  The woods appeared to contain but few birds. I 
heard a Tanager calling, Jays screaming and Vireos
calling at evening when a number of Robins were also
assembling, to roost apparently, in the pines behind
Ball's Hill. Across the river, where I went for a 
short time just after dinner, I saw two Oven birds
and heard a Grosbeak. Swallows and Swifts were
numerous all day over the meadows. Late in 
the afternoon I saw two Great Blue Herons flying
over the Barrett meadow.
