Mass.
Concord.- Cloudless and very warm with strong S.W. wind.
  George Carroll came to-day and with him I drove
to Ball's Hill at 9.30 A.M. There were many little
things to be attended to at my cabin where I spent
the entire day.
  Song Sparrows and Swamp Sparrows were singing
freely but I heard almost nothing else except an
occasional Robin and a few Red-eyed Vireos. In the
forenoon a Virginia Rail called Ki-Ki at frequent
intervals in the marsh across the river.

  The flying notes of the Cicada are now a frequent
sound in the oak woods but these insects do
not seem to be as numerous about Concord as
they are in Cambridge.
