  Gilbert [Robert Alexander Gilbert] & I left Cambridge at 8.50 A.M.
& motored to Concord via Turnpike past
Fresh Pond, thence by Hill's Crossing to
Arlington, thence through Lexington &
Bedford. Very few birds. Saw no Robins
anywhere save in Bedford village. A
Mourning Dove rose from the road near
Carlisle Bridge & flew low along it just
ahead of our car.
  Reached Farm at 10. Found the men
spraying & joined them for remainder
of day. They worked with hand pump &
sprayed apple trees mostly. Duren came 
with his new power engine at 3 P.M.
& worked one hour spraying a lot
of birches along the run. Local birds
singing well. No north-bound migrants.

Ther [Thermometer] Thursday, June 1, 1916  Wea [Weather] Glorious.
More north-bound migrants
  Brilliantly clear & just comfortably cool

  North-bound Migrants Black-poll Warbler [Blackpoll Warbler] [male] [in full song],

In these oaks were also singing a Yellow-
throated Vireo, a Red-eye [Red-eyed Vireo], a Redstart & a 
Wood Pewee. Elsewhere about the Farm 
I heard the usual summer birds
including a Yellow Warbler, at least 3
Chestnut-sides [Chestnut-sided Warblers] 2 Maryland Yellow-throats,
Indigo bird [Indigo bunting], Grosbeak etc. Failed to
note either Tanager or Oriole.
  Duren brought two spraying outfits this
morning and we had five men busy
with them all day working mostly 
among the big oaks & elms in & about
the cultivated lands but getting into 
the Run & Pulpit Rock woods in P.M.
  Gypsy larvae swarming in spots but
not generally or widely distributed & still
very small. Have seen no Forest Tent 
caterpillars as yet. Out all day with men
& very tired tonight.
