Rh their circuits are performed at a considerable elevation, with a lightness and ease that are truly admirable. They play over the river, the field, or the city with equal grace, and during spring and summer you might imagine their object was to fill the air around them with their cheerful twitterings. When the weather lowers, they move more swiftly in tortuous meanderings over the meadows, and through the streets of the towns ; they pass and repass, now close to the pavement, now along the walls of the buildings, here and there snapping an insect as they glide along with a motion so rapid that you can scarcely follow them with the eye. But try : — there she skims against the wind over the ruffled stream ; up she shoots, seizes an insect, and wheeling round, sails down the breeze with a rapidity that carries her out of your sight almost in a moment. Noon arrived, and the weather being sultry, round the horse or the cow she passes a thousand times, seizing on each tormenting fly. Now she seems fain to enter the wood, so close along its edge does she pursue her prey ; but spying a Crow, a Raven, a Hawk or an Eagle, off she shoots with doubled speed after the marauder, and the next instant is seen lashing, as it were, the object of her anger with admirable dexterity, after which, full of gaiety and pride the tiny thing returns towards the earth, forming to herself a most tortuous path in the air.

On the ground the movements of this Swallow are by no means awkward, although, when compared with those of other birds, they seem rather hampered. It walks by very short steps, and aids itself with its wings. Should it be necessary to remove to the distance of a few yards, it prefers flying. When alighted on a twig, it shews a peculiar tremulous motion of the wings and tail.

The song of our Barn Swallow resembles that of the Chimney Swallow of England so much that I am unable to discern the smallest difference. Both sing on the wing and when ahghted, and the common tweet which they utter when flying off is precisely the same in both. Their food also is similar ; at least that of our bird consists entirely of insects, some being small coleoptera, the crustaceous parts of which are disgorged in roundish pellets scarcely the size of a small pea.

I have represented a pair of our Barn Swallows in the most perfect spring plumage, together with a nest taken from one of the rafters of a barn in the State of New Jersey, in which there was at least a score of them.
