1909
May 19
Concord, Mass.
Partly cloudy & very cool with brisk E. wind.
  Early this morning before the east wind started the
river was perfectly calm & thinly veiled in mist, the
sky filled with fleecy clouds. The sun shone dimly 
at intervals through both cloud & mist. These conditions
lasted up to about 8.30. At 7.30 I heard a Snipe
drumming in the direction of Great Meadow. He kept
it up without cessation for more than half an hour,
usually drumming about every eight seconds although
the intervals of silence were sometimes double that length.
The humming sound ordinarily lasted about three or four
seconds at each repetition. Although I paddled up 
river for some distance and thereby got rather near
when the bird was performing I could not see him
partly because of the misty atmosphere & partly
because there were so many Swallows flying over the meadows.
