  F.M. Chapman came from New York last night and
joined me this morning at a little after nine. At 11 A.M.
we started down river in the two canoes. There was
almost no wind and the light was soft & restful. The
only birds heard singing were an old and a young Song Sparrow
and a Warbling Vireo. Bobolinks clinking. Only one Rail
called in the rice at Beaver Dam when we paused opposite
it and struck the water with our paddles.
  After dining at the cabin we took a long walk and
set about two dozen "cyclone" traps for Mice and Shrews.
We saw two small mixed flocks of Titmice & Warblers
and a good many scattered birds - Cat birds, Wilson's Thrushes
etc.
  As twilight was falling a Black & White Creeper gave the
warbling song, a Maryland Yellow Throat sang twice on
wing giving the full flight song each time, and a 
Wilson's Thrush near the cabin sang brief snatches in
a low tone. We heard another Thrush calling on Holden's
Hill and earlier in the day saw at least three more
in the Davis Swamp. 
  A number of Barn Swallows circling over the river
at evening were joined by a small Bat which flew
about with them for some time.
