Concord (Farm & Ball's Hill) - Cambridge
Ther [Thermometer] Thursday, June 3, 1915 Wea [weather] 
Fine
Sunny but hazy. Cool with fresh
N.E. [northeast] wind.
  Spraying most of day with George
& two of Duren's men who brought
his old hand pump apparatus which
still does good service. We spent
forenoon in Pulpit Rock woods &
Birch Field dealing chiefly with big
isolated oaks. In afternoon we went
to Ball's Hill where, however, I could
not stay long. The oaks on the
crest of this hill are very badly
infested with Gypsy caterpillars.
Heard a Blackburnian Warbler singing
there in a pine & saw a pair of
Wilson's Thrushes on edge of swamp.
Many birds singing in Pulpit R. [Pulpit Rock] woods,
a Blackburnian, Grosbeak, Wood Pewee,
Phoebee [Phoebe] & Yellow-bill Cuckoo [Yellow-billed Cuckoo] among others.
  Gilbert & I left Farm at 3.45
P.M. & motored to Cambridge via
Bedford & E. Lexington [East Lexington] & Waverley.
C. [Caroline Brewster] & E.R.S. [Elizabeth R. Simmons] at home, the latter in bed
with badly sprained back.
