Canoe trip up Sudbury River.
1891
April 25
Mass. 
Concord to Maryland. - At  3.30 A.M. Bolles roused
me by shaking the tent of my canoe. There
was a faint indication of dawn in the East
but the moonlight had hardly begun to pale
a Brown Thrush was singing glowingly on
Fairhaven Hill and a Song Sparrow soon joined
in followed by a Robin, a Spotted Sandpiper,
a Whippoorwill and a Swamp Sparrow. This
were all the species heard during the first 
half hour.
  At 4 A.M. we started back from camp passing
through a dense woods of young pines and
coming out in an open field. The moon hung
low in the west but its light was still more 
dominant than the ever growing day light. The
sky to the south & east was cloudless and
spangled with stars, but in the north it was
filled with a leaden mass of clouds. These
rolled steadily and rapidly overhead blotting 
out the moon and the rosy tints where the
sun was about to appear. The air was sharp
and the grass white with hoar-frost. We had
to keep moving to overcome the chill that
despite our warm clothing pierced us. More
birds singing. A Ruffed Grouse drumming, a Grass Finch,
Red-wings (4.20), Chickadee (4.21) Field Sparrow
Crows, Hermit Thrush (harsh note only), Chippy (4.27)
Miniotilta (4.35) Pine Warbler, Cow-bird, Flicker (4.49),
Yellow-rump (4.50), Blue Jay (4.55), Rusty Black-
bird, Bank Swallows, and Ruby-crowned Kinglet
(singing at 5 a.m.). A pair of Wood Ducks
