14 [degrees] Fine
Clear & bitterly cold with strong
northerly wind.
  Garden birds: Chickadee heard in lilacs;
2 Robins (both dull colored) and 5 Starlings
eating fruit of Parkman apple which they
visited & revisited at frequent intervals
through day.
  Resumed work on Umbagog Introduction
& kept at it all forenoon. Fisher Ames
called by appointment at 2 P.M.
to consult me about a book on
birds which he proposes to write
for use by school children & others.
We discussed it & various other
things for two hours or more.
He is an intelligent & interesting
man whom I was glad to meet.
I advised him to make free use of
Mus. C.Z. [Museum of Comparative Zoology] library & specimens which
he says may be of great service to
him in connection with his work.
C. [Caroline Brewster] progressing well. E. [Elizabeth R. Simmons] read Trollope

Cambridge
Ther [Thermometer] Tuesday, Dec. 11, 1917 [December 11, 1917] Wea [Weather]
12 [degrees] Fine
Clear and intensely cold with 
northerly winds diminishing in force.
There has been something peculiarly 
penetrating & trying about the cold
of these past few days. Several of our
friends have remarked the fact &
our own house has been uncomfortably
frigid despite generous burning of both
coal & wood.
  Garden birds: Represented, as far as I
had opportunity to observe, by a single
White-throated Sparrow and nothing else.
  My day devoted to the customary
task of revising the Introduction to
Umbagog at which I am making
no more than the usual discouragingly
slow and difficult progress yet
enjoying it, nevertheless.
  C. [Caroline Brewster] spent the day in her chamber
where I was thrice with her for
half-an-hour at a time. E. [Elizabeth R. Simmons] read
Trollope's "Vicar" [The Vicar of Bullhampton] to me for an 
hour after supper.
