 much esteemed, and the feathers form an important article of commerce. The call of the Canada Goose resembles the syllables, "Hawk, hawk, hawk, awhawk, awhawk."

THE SNOW GOOSE.

The (Anser [Chen] hyperboreus) has the entire plumage of a pure white, with the exception of the first ten quills, which are black, with white roots, and white shafts tipped with black. In young birds the feathers on the upper back, shoulders, a portion of the neck, the breast, and sides are blackish grey; the head and nape are shaded with grey; the lower back and feathers on the upper tail-covers are dark grey; the primary and secondary quills greyish black, the latter bordered with greyish white; the tail-feathers are also dark grey, and similarly edged. The eye is dark brown, the beak dull pale red, edged with black, and the foot pale bright red. This species is from twenty-six to twenty-seven inches long, and from fifty-two to fifty-three broad; the wing measures sixteen and the tail six inches.

"The young of this species," says Audubon, "begin to acquire their whiteness about the head and neck after the first year, but the upper parts remain of a dark blueish colour until the bird suddenly becomes white all over, at least this is the case with such as are kept in captivity. My friend Dr. Bachman, of Charleston, South Carolina, kept a male Snow Goose several years along with his tame Geese. He had received it from a friend while it was in its grey plumage, and the following spring it became white. It had been procured in the autumn, and proved to be a male. In a few days it became very gentle, and for several years it mated with a Common Goose, but the eggs produced by the latter never hatched. The Snow Goose was in the habit of daily frequenting a mill-pond in the vicinity, and returning regularly at night along with the rest; but in the beginning of each spring it occasioned much trouble. It then continually raised its head and wings, and attempted to fly off; but finding this impossible, it was anxious to perform its journey on foot, and it was several times overtaken and brought back, after it had proceeded more than a mile, having crossed fences and plantations in a direct course northward. This propensity cost it its life; it had proceeded as far as the banks of the Cooper River, when it was shot by a person who supposed it to be a wild bird." A Snow Goose kept by Audubon himself exhibited the same desire to go northward on the return of spring.

When migrating northward, although they start at the same time, the young and old keep in separate flocks, the young continuing to remain apart from the old even when approaching the higher latitudes. During the whole winter, indeed, they remain divided, although in the same localities; and Audubon informs us that, although the young and old are often seen to repose on the same sand-bar, the flocks keep at as great a distance as possible from each other.

The SEA GEESE (Bernicla) are comparatively small, compactly-built birds, with short necks and moderately large heads; the short delicate beak is strong, broad and high at its base, slender towards its tip, and slightly denticulated at its margins; the foot is low, but powerful; and the wing so long as to extend as far as the tip of the short tail, which is rounded at its extremity. The thick plumage is principally of a deep grey, marked with black, white, and reddish brown. These Geese are met with in the extreme north of Europe, Asia, and America; the American, formerly considered as distinct from the European, being evidently only a variety. The home of these birds is to be found upon the coasts and islands situated between 60° and 80° of north latitude. Only a few breed in Iceland; but in Spitzbergen they are very numerous, and further east they abound throughout the summer along all the shores of the Icy Ocean; they are likewise numerous in Hudson's Bay and the neighbouring waters. From the above inhospitable regions they make annual pilgrimages to warmer
