Concord (Ball's Hill) April 24, 1904
  Brilliantly clear with light W. [west] wind. The
warmest day thus far  - uncomfortably warm in the sun.
   Rambled around the Hill & to Pine Park
after breakfast. George V. Leverett arrived at 10.30.
We started for Davis's Hill where we met Shattuck the
gypsy moth man. A little later Edward Emerson & his
two sons appeared. We had a long talk & walked
through the Holden Hill woods with them as they were
now on their way back. In P.M. we took a long tramp
to the farm & the big pine woods beyond Abbot Lawrence's.
Birds rather silent save in the early morning when
they sang freely.
