  A Robin in front of the house was singing
sotto voce, about noon, in a barberry bush the berries
of which it ate greedily during intervals of silence.
This is the first Robin song I have heard. The birds 
are few in numbers & chiefly confined to pasture lands.

 A cotton-tail Rabbit, startled by Garry the foreman,
took a nearly straight course across Birch Field
running at very unusual speed & after notably appearing
and disappearing among the scattered clusters of trees.
Edward W. Emerson, who was with me, said that
when it crossed an opening it looked to him like
a dark line several yards in length and that his eye
utterly failed to record it as the small, swiftly movement
object which his brain assured him it must be. This
was exactly the impression it made on me as it
passed us at a distance of about 100 yards.
