Cambridge 
Ther [Thermometer] Tuesday, Aug. 14, 1917 [August 14, 1917] Wea [Weather] 
Fine
Clear, calm, warm yet not oppressively
so.
  Garden swarming with Butterflies, large
& small, of several kinds. Tree Crickets
chirping merrily yet not in full force
as yet.
  Garden birds. Very few. 2 Jays screaming
by day, a Screech Owl uttering the
cat-like eh-ow at 9 P.M. and an
Oriole singing a little in early morn
were all I could identify. There must
have been one or two Warblers, also,
for their chirping was heard through
my open window soon after daybreak.
  Spent most of day in Museum.
Copied & mailed my Museum Rep. [Report]
& wrote several letters. Going out to
post them at 6.30 I met an Army
officer in khaki & walked down street
with him. He told me various interesting
things about the Harvard Contingent.
  Played Victrola records for Lotty [Lotty Kettell] & the
others from 7.40 to 8.45 P.M.

Cambridge 
Ther [Thermometer] Wednesday, Aug. 15, 1917 [August 15, 1917] Wea [Weather]
Fair
Partly sunny mostly cloudy & hazy. Rather
warm & almost windless.
  Garden birds. One Robin, a Red-eye [Red-eyed Vireo]
singing freely but listlessly, an ad. [adult] Oriole
fluting a few notes, one Grackle, 2 or 3 House
Sparrows, 2 Jays, 4 Swifts at evening.
  I am wondering if the frequent presence
by night in the Garden of one or more
Screech Owls may not account for the
extreme scarcity of all other birds by day.
Many of these have doubtless departed on
migration but there should at least be plenty
of House Sparrows whereas no more than one or
two have been seen daily of late.
  All the presumably passage migrants noted
thus far have belonged to species which breed
in the Cambridge region. Not one more northern
breeding species has appeared as yet. This
is unusual, to say the least.
  Spent day in Museum writing letters.
Sent my Colo. Springs [Colorado Springs] specimen of Bendire's
Thrasher to Col. Museum [Colorado Museum of Natural History] at Denver.
  Called on the Spelmans in their garden at
6 P.M. Played Victrola to Lotty [Lotty Kettell], C. [Caroline Brewster] & E. [Elizabeth R. Simmons]
for an hour after supper.
