worked mostly in the morning, having the early hours all to
themselves.

Another pair of blue grossbeaks built in a graveyard within the city
limits. The nest was placed in a low bush, and the male continued to
sing at intervals till the young were ready to fly. The song of this
bird is a rapid, intricate warble, like that of the indigo-bird,
though stronger and louder. Indeed, these two birds so much resemble
each other in color, form, manner, voice, and general habits that,
were it not for the difference in size,--the grossbeak being nearly as
large again as the indigo-bird,--it would be a hard matter to tell
them apart. The females of both species are clad in the same
reddish-brown suits. So are the young the first season.

Of course in the deep, primitive woods also are nests, but how rarely
we find them! The simple art of the bird consists in choosing common,
neutral-tinted material, as moss, dry leaves, twigs, and various odds
and ends, and placing the structure on a convenient branch, where it
blends in color with its surroundings; but how consummate is this art,
and how skilfully is the nest concealed! We occasionally light upon
it, but who, unaided by the movements of the bird, could find it out?
During the present season, I went to the woods nearly every day for a
fortnight, without making any discoveries of this kind, till one day,
paying them a farewell visit, I chanced to come upon several nests. A
black and white creeping warbler suddenly became much alarmed as I
approached a crumbling old stump in a dense part of the forest. He
alighted upon it, chirped sharply, ran up and down its sides, and
finally left it with much reluctance. The nest, which contained three
young birds nearly fledged, was placed upon the ground, at the foot of
the stump, and in such a position that the color of the young
