self. She alights, and with delicate steps, aiding her motions by gentle
flappings of her wings, she advances towards the edge, takes a few drops,
plumes herself, and returns to her nest, filling as she flies her wide mouth
with insects. Should her nest be not finished, or need some repair, she
carries a pellet of tempered earth in her bill, or picks up a feather that
has been shed by a goose or a fowl, or from the hay carries ofi* a stem of
long grass to mix with the mortar. As the heat becomes oppressive to
all animals save herself, she passes and repasses round the cattle under
the shady trees, and snaps off' each teasing insect. Now on the fence she
alights by the side of her ofl'spring, or teaches them to settle on the slender
dry twig of some convenient tree. There they plume themselves, chat-
ter, and rest for a while, until, sorry to have lost so much time, they
launch into the air, to continue their sport.
The summer has now closed, and the Swallows, young and old, assemble on the roof of the barn, and in a few days are joined by many others, reared in humbler situations. Each parent bird perhaps tells her young that, before dismal winter cramps the insects, they must escape to some far distant land, where the genial heat continues unabated. The talk becomes general, and day after day increases. The course of the journey is pointed out to each inexperienced traveller, by means of short excursions through the air. At length a chiU night comes, the following brings a slight frost, the time has arrived, and on the next bright morning the flocks rise high above the trees, and commence their journey. The Barn Swallow makes its first appearance at New Orleans, from the middle of February to the first of March. They do not arrive in flocks, but apparently in pairs, or a few together, and immediately resort to the places where they have bred before, or where they have been reared. Their progress over the Union depends much on the state of the weather ; and I have observed a difference of a whole month, owing to the varying temperature, in their arrival at different places. Thus in Kentucky, Virginia, or Pennsylvania, they now and then do not arrive until the middle of April or the beginning of May. In milder seasons, they reach Massachusetts and the eastern parts of Maine by the 10th of the latter month, when you may rest assured that they are distributed over all the intermediate districts. So hardy does this species seem to be, that I observed it near Eastport in Maine, on the 7th May 1833, in company with the Republican or Cliff' Swallow, pursuing its different avocations, while masses of ice hung from every cliff', and the weather felt cold
