be termed "whistling". As nearly as I could make out
there were fully eight birds in the flock. After they
had passed Davis' Hill they turned back, just as
did those seen on the 5th. They seemed anxious to
alight but after describing a great circle they kept 
on towards the north east. These birds left the
others, however, and went off to the South ward
but without lowering their flight. The flock was
within our hearing for ten or fifteen minute and
I have never heard Geese make more noise. It
was truly inspiring to hear them. My men seemed
quite as excited and interested as I was myself.
  I directed my sunset walk to Pine Park where,
besides the two Fox Sparrows already mentioned, I
heard two Song Sparrows and saw a Tree Sparrow.
The Robin singing was exceptionally fine and general
as the misty twilight closed in. I could hear
at least three or four birds at once and all
were at their very best.
  As it was getting dark a Great Horned Owl,
the first that I have noted here this season,
hooted three or four times in the direction
of Pine Ridge.
  I heard Wood Frogs, for the first time, this
afternoon, in two places but only one Frog in
each place. The Hylas have not begun peeping here
as yet although Roland Hayward told me yesterday
that he heard them at Milton last week. I
cannot understand why they are so very late
this year. There is no ice or snow left anywhere now
and the ground is almost everywhere free from frost.
