If the chimney would be a dark, dead hole without the swifts, how empty the summer sky would be were they not skimming, darting, wiggling across every bright hour of it! They are tireless fliers, feeding, bathing, love-making, and even gathering the twigs for their nests on the wing, never alighting, in fact, after leaving the chimney until they return to it. They rest while flying. Every now and then you will see them throw their wings up over their heads till the tips almost touch, and, in twos or threes, scale along to the time of their jolly, tuneless rattle.
From May to September, is there a happier sight than a flock of chimney-swallows, just before or just after a shower, whizzing about the tops of the corn or coursing over the river, like so many streaks of black lightning, ridding the atmosphere of its overcharge of gnats! They cut across the rainbow and shoot into the rose- and pearl-washed sky, and drop—into the depths of a soot-clogged chimney!
"They cut across the rainbow."
These swallows used to build in caves and in clean, hollow trees; now they nest only in chimneys. So far have they advanced in civilization since the landing of the Pilgrims!
Upon the beams in the top of the barn the brown-breasted, fork-tailed barn-swallows have made their mud nests for years. These birds are wholly domesticated. We cannot think of them as wild. And what a place in our affections they have won! If it is the bluebirds that bring the spring, the barn-swallows fetch the summer. They take us back to the farm. We smell the hay, we see the cracks and knot-holes of light cutting through the fragrant gloom of the mows, we hear the munching horses and the summer rain upon the shingles, every time a barn-swallow slips past us.
For grace of form and poetry of motion there is no rival for the barn-swallow. When on wing, where else, between the point of a beak and the tips of a tail, are there so many marvelous curves, such beautiful balance of parts? On the wing, I say. Upon his feet he is as awkward as the latest Herreshoff yacht upon the stays. But he is the yacht of the air. Every line of him is drawn for racing. The narrow, wide-reaching wings and the long, forked tail are the perfection of lightness, swiftness, and power. A master designed him—saved every possible feather's weight, bent from stem to stern, and rigged him to outsail the very winds.
