Ther. [Thermometer]FRI. NOV. 26, 1909 [Friday, November 26, 1909] Wea. [Weather] 
Fine.
The sky cleared before noon and
the afternoon was sunny & mild
with light westerly wind.
  Spent entire day in Museum
working (about six hours in all)
on proof of A.O.U. [American Ornithologists Union] Check List.
A big package of it arrived
from Allen this morning & I
sent the whole of it back to
him by this evening's mail.
I paid most attention to the
ranges of the birds, especially
in the eastern states, finding a
good many points open to
suggestions or even correction.
  Oliver Ames Lothrop called at 8.30
staying until 10 (P.M.). I had not
seen him before for over a year.
  Two Blue Jays in Garden; nothing else.

40º max. [40 degrees maximum]  Fine.
  Brilliantly clear with little or no wind.
Air crisp & bracing but not cold. No
frost in ground. Grass still bright green
on city lawns.
  Spent day in Museum. Worked on
Merrill Memorial but made little
progress. I cannot find the letters, 
papers etc, I thought I had, bearing
on the subject, & I am rather short of
necessary material for an adequate memorial.
Nelson is pressing me for it &
expects me to have it ready to
read at the A.O.U [American Ornithologists Union] Meeting.
  As I was sitting at my desk
about sunset I heard a grating
chatter outside & looking up saw a
Carolina Wren with tail cocked over
his back perched on a post within
a yard of my study window. A Jay &
a Crow the only other birds about.
