46 [degrees] Fair
Thin cloudy, windless, rather
cool but not chilly.
  Garden birds. A Robin a Fox
Sparrow & a Flicker in full
song in early morning & again
towards evening. Several Grackles 
in Jungle. Hairy W. [Hairy Woodpecker] heard
there & a Sparrow Hawk (calling
many times) somewhat further
off & apparently in the Horsfords
grounds.
  Percy tells me that while on his
way here early this morning
he heard Robins singing
almost everywhere between 
Oxford Street & our place. I
probably heard more than 
one while lying in bed at
daybreak.
  Spent most of day in 
Museum writing letters.
Took walk outside around
our grounds with C. [Caroline Brewster] in P.M.

Fair
Mostly cloudy but with bright
sunshine fr. [from] 2 to 4 P.M. Warm
& windless all day. Rain at night.
  Garden birds. Robin in full song
at morn & eve  [evening], Fox Sparrow & Junco
at intervals all day, Flicker &
Bluebird about 3 P.M. Heard the 
Bluebird repeat his song five or
six times, not far off. It seemed
to come always from the same
direction & distance but he may
have been on wing. In late
P.M. heard a Downy & a Hairy
W. [Hairy Woodpecker] calling in the Jungle. A
few Grackles there now & then.
  To Harvard Square in Ford car 11 A.M.
Dr. Andrews (Junior) filled a tooth
& gave me a third treatment of
oxygen-boracic acid. This had
again a weakening effect but less so
than the last. Spent P.M. in
Museum & garden doing nothing.
