Fine
Clear & warmer with light W. [west] wind.
Grass again fully exposed &
almost as green as ever.
  A few House Sparrows the only
birds seen about our place to-day
even the five Chickadees, so constantly
present of late, failing to appear.
  My day spent in Museum as usual.
The forenoon had to be devoted to
a final revision of Marsh Hawk
story. Immediately after dinner
I began story of Sharp-shin Hawk [Sharp-shinned Hawk]
composing two pp. [two pages] before 6 P.M.
when I ceased work. C.[Caroline] kept to
her room & couch all day. E.R.S. [Elizabeth R. Simmons]

Trollope's "He Knew He Was Right".
Cambridge - Concord.
Ther [Thermometer] SAT. DEC. 13, 1913 [Saturday, December 13,1913] Wea [Weather]
 Perfect.
Cloudless skies, brilliant sunshine,
mild temperature & general absence of
wind combined to make a rarely perfect day.
Faxon [Walter Faxon] called at 9.15 A.M. to look over 
my N.E. [New England] specimens of Parus "hudsonicus" all
of which prove to be typical littoralis.
  At 11.53 Gilbert [Robert Alexander Gilbert] & I started for Concord
in the Ford car reaching that village just an
hour later. We went by favorite road
through Piety Corner & Lincoln. The only birds
seen were a gray Loon in Hobbs Bank Reservoir,
a brown Northern Shrike in Lincoln almost
exactly where I saw one Nov. 25 & a Crow
near Sandy Pond. Reached our Farm at 1.15
& spent nearly two hours there eating lunch
in front of house. It seemed almost summer-
like there with flies buzzing about. A Chickadee
came to the suet, 2 Crows alighted in an
elm, a big flock of Redpolls (fully 50) were
rising & whirling & calling among some
birches across the road. Flushed two Partridge
& heard a Creeper [Brown Creeper], in the Run & saw
tracks of a Deer & a Pheasant. (A cock seen
on Punkatasset Hill on our way from Concord)
Burbank & Zeph had just got in new
water pipes to barn, 5 feet under ground.
  Gilbert & I started back at 3.10. Returned
via Carlisle Bridge, Bedford, Lexington, E. Lex. [East Lexington]
Belmont Springs & [Marple?] Street. Only 2 Crows
seen.
