1606.
May 16
  Brilliantly clear and oppressively warm with scarce a breath
of wind. As most of the deciduous trees are still leafless there
was little shade to be found from sun's intense rays. Ther. 50 degrees - 87 degrees.
  Solitary Sandpiper. Saw one on the river bank at Flint's Bridge.
Arrival.
  Apparently only a few migrants came last night. I heard
a Black & Yellow and two Black-throated Blue Warblers singing
in the Barrett Run this forenoon & these I think have arrived
since yesterday. Usnea Warblers still haunt the apple trees
which were in nearly full bloom to-day.
  Returning from a drive to Concord this morning I
saw a great swarm of Bank Swallows flying about
a new sand bank which Peterson has just opened on
the west side of Dakin's Hill. With the aid of my
glass I counted over sixty fresh holes in this bank.
The colony promises to be as large as that which
existed on Bedford Street, Concord several years ago.
