Ther. [Thermometer] Wed. [Wednesday] Dec. 6, 1911 [December 6, 1911] Wea. [Weather]
Fine
Clear, calm, comparatively mild.
  Spent day in Museum working 
on Gull article & making wretched 
progress. Somehow I seem to have
got into the mental doldrums, if 
such there be, and to be unable to 
extricate myself. A severe headache
- most rare in my experience - was
brewing through the day and floored
me just before I left my desk at
6.30 P.M. C. [Caroline Brewster] & I passed the
evening in the morning room, she
reading to me for upwards of an hour
from "Gwen" [Guenn] the old-time story by
Blanche Howard [Blanche Willis Howard] of which Ned Simmons [Edward Emerson Simmons]
is the hero & wonderfully sketched.
Saw in Garden 4 Golden crests, a
Chickadee, a Blue Jay & a Flicker.

Ther. [Thermometer] Thurs. [Thursday] Dec. 7, 191 [December 7, 191]1 Wea. [Weather]
Fine
Clear, calm, mild. Heavy hoar frost.
  Spent day in Museum working on 
Flight of Gulls article. It went well
this time & I had it practically
finished by 6 P.M. when I knocked 
off & came into the house. Will &
Alice Stone arrived at 7 to dine with
C. [Caroline Brewster] & me. They stayed until 9.30.
Galley proof of the Purdie Memorial
was sent up from Wheeler's this P.M.
I shall tackle it the first thing
to-morrow. I read the closing paragraph
to Will Stone this evening & he liked it.
2 [in a flock] Chickadees, 2 [in a flock] Golden-crests, a
Flicker, a Jay & a Downy Woodpecker
were noted in the Garden to-day.
Gray Squirrels began on one [?] several
days ago & have since eaten almost all.
