Ther. [Thermometer] Wed. [Wednesday] May 17, 1911 Wea. [Weather]
Fine
Clear and warm with light S.E [Southeast]
to S.W. [Southwest] wind. A "rare day" with
birds singing like mad from early
morning to evening twilight. I noted
only one north bound migrant, a
Black-poll. Evidently the migratory
wave of yesterday passed on last night.
  Spent most of forenoon with
Duren & his men. They worked all
day spraying both sides of the road
to the Ritchie place, the southern
part of Berry Pasture, our lane, the
remainder of the orchard & the
thickets & wood edges on the eastern
slopes of the hill below farm & orchard.
I missed the Indigo Bird heard yesterday
but nothing else.
  In P.M. Gilbert, James, Zeph & I went
to Ball's Hill where we spent two
hours putting things in order. Very
few birds there. Blue Jay on her nest.
Redstart singing near cabin.
Had farm house cleaned to-day.
