Blue and Bluish 
of the delicacy, richness, and brilliancy of-the living tints. But, 
happily, the beautiful barn swallow is too familiar to need descrip- 
tion. Wheeling about our barns and houses, skimming over the 
fields, its bright sides flashing in the sunlight, playing ‘‘ cross 
tag” with its friends at evening, when the insects, too, are on 
the wing, gyrating, darting, and gliding through the air, it is no 
more possible to adequately describe the exquisite grace of a 
swallow’s flight than the glistening buff of its breast. 
This is a typical bird of the air, as an oriole is of the trees 
and a sparrow of the ground. Though the swallow may often 
be seen perching on a telegraph wire, suddenly it darts off as if 
it had received a shock of electricity, and we see the bird in its 
true element. : 
While this swallow is peculiarly American, it is often con- 
founded with its European cousin Hirundo rustica in noted 
ornithologies. 
Up in the rafters of the barn, or in the arch of an old bridge 
that spans a stream, these swallows build their bracket-like nests 
of clay or mud pellets intermixed with straw. Here the noisy 
little broods pick their way out of the white eggs curiously spotted 
with brown and lilac that were all too familiar in the marauding 
days of our childhood.
