94 [degrees] - Boston (off [official]) Terrific heat. Fine
88 [degrees] - Concord Farm
Terrific heat & wilting humidity but
slightly atoned for by a light westerly to
southerly breezes. Altogether a more 
trying day even than yesterday &
indeed one of the worst I have ever
known here.
  Continued dearth of birds. Almost
none about the Farm. Nuthatches of both
kinds calling in dooryard elms, a 
Brown Thrasher in Berry Pasture.
Solitary Black-poll Warbler seen.
in birch, Ritchie Place. A Catbird,
a Song Sparrow, several Chippies [Chipping Sparrow],
Crows & Jays, also a Flicker.
  It was too hot to work out
doors or to write in house. I 
tried both in vain & passed a 
profitless day doing little or
nothing. The men stuck to their 
tasks fairly well. Little "Tim" was
utterly prostrated. Gilbert [Robert A. Gilbert] motored
Henry [Henry W. Henshaw] to Westboro to see his sister Lizzy
who has just had paralytic stroke. They
returned at 4. Dexter came down to pass evening.

Ther [Thermometer] Thursday, Sept. 16, 1915 [September 16, 1915] Wea [Weather]
94 [degrees] - Boston (off [official]) Intense heat. Fine
88 [degrees] - Farm
Clear, intensely hot and humid, almost
or quite windless. These conditions prevailed
up to 4.30 P.M. after which two heavy
thunder showers passed, one to north, the
other to south giving us only a little
rain but bringing refreshing coolness.
  Rarely if ever before have I experienced
at any season such an intolerably
hot & oppressive day. I tried in
vain to write and could find no
comfort anywhere out of doors.
Man & beast seemed equally
unable to cope with it although
our men & horse did keep at work
in shady places. Of birds there
were almost none to be seen or
heard. The Cicadas "fried" all day
& after dark there was a full
& rarely animated chorus of insect
musicians.
  Henry motored to Wellesley with 
Gilbert [Robert A. Gilbert] to see his sister Annie. I 
spent much of day in house. We
had a Victrola concert this evening.
