  To Ball's Hill for the day, driving down and
back. Took a walk over my grounds in the
forenoon. There was a single Canadian Warbler
singing in the maple swamp and I started
a Night Heron from the pines above the glacial
hollows. The heat was intense and few birds
were singing. One of my men showed me a Thrasher's
nest built on the ground among dry oak leaves
at the foot of a cluster of oak sprouts on the 
steep hillside near my cabin. The locality was very
open and exposed and after the bird had left
the nest the three eggs which it contained were 
conspicuous yards away for the nest was in no 
way arched over or concealed by either leaves or branches.

  In the evening a little after sunset as I was
walking up to Mrs. [?] I heard a Henslow's 
Sparrow singing in the meadow behind Fergusson's
but the bird was silent when I returned at 9.30
P.M.although the night was very warm and bright
with the light of a half moon.

  At 10P.M. a Virginia Rail began calling cutt[?]
in the Buttnick's meadow but it kept it up
only ten or fifteen minutes.


  Spring has passed into summer promptly 
at the conventional date & at a bound. The woods
this evening seemed to be in nearly full foliage.
Great swarms of Dragon-flies appeared to-day &
Mosquitos were [?] troublesome for the first time
