Unrestricted U-Boat War begins Stormy
Dark cloudy & densely foggy with
light rain, from daybreak to
mid-forenoon; after that the rain
ceased & a cold wind arose quickly
turning the wet sidewalks into
ice-coated ones dangerous to traverse.
Still colder and yet cloudy to-night.
  Garden birds. Handsome, adult
White-throated Sparrow feeding with
a mob of House Sparrows on grain
thrown out for the Pigeons &
half embedded in icy slush.
A Jay heard screaming.
  Letter writing continues to
claim most of my time but
a good deal of this was devoted
to-day to reading newspapers
filled with disturbing & very
ominous reports concerning
Germany's proposed submarine war
on all commerce beginning to-day.
  We spent evening in hall. E. [Elizabeth R. Simmons]
finished "Villette" a truly fine story.

Ther [Thermometer] Friday, Feb. 2, 1917 [February 2, 1917] Wea [Weather]
10 [degrees] Fine
Clear & cold with fresh N.W. [northwest] wind.
Everything frozen hard again & all
snow surfaces covered with a thin
icy crust glistening like polished
metal in the sunlight. Sidewalks 
very slippery.
  Garden birds. A White-throat [White-throated Sparrow] feeding
on millet seed with a dozen or more 
House Sparrows. A Crow heard cawing
afar off.
  Wrote letters in forenoon & recopied
part of Goose & Guinea hen story in
afternoon. Cope of Philadelphia,
cousin of late Prof. Cope but a
much younger man (certainly not
above 35 years of age) called on me
at 4.30 staying until past 6. 
I showed him the museum &
some birds & eggs in which he seemed 
to take much interest. He impressed
me very favorably.
E. [Elizabeth R. Simmons] read aloud to us this evening
beginning Charlotte Bronte's "Shirley".
