before," writes M. Cornèly, "but now I think he must be mad. He attacks every living thing indiscriminately. One of my large Cranes happened to come in his way; he flew at him, and although the keeper was not a hundred yards off, and ran as fast as he could to part them, the poor Crane was killed before he could interfere. One night the Gander got into the stable where another of these birds was kept, and in the morning the body of the Crane was found almost hacked to pieces." However ornamental these Geese may be, it is evident that it is only where they have plenty of room to themselves and are not likely to interfere with other animals, that they are eligible subjects for domestication. * * * * * [Illustration: THE RUDDY SHELDRAKE, OR BRAHMINY DUCK (_Casarca rutila_). ONE-FOURTH NATURAL SIZE.] The DUCKS (_Anates_) constitute the most numerous and varied family of the entire order, and are at once distinguishable from the Geese by the flatness of their feet, and from the Swans by the shortness of their necks. In these birds the body is short and broad, the neck short or moderately long, and the head thick; the beak, which is about the same length as the head, is either of uniform breadth, or is highest towards the tip; the base of the bill is more or less high, and in some instances furnished with an excrescence; the upper mandible is arched, and projects so far over the sides of the lower one as partially to enclose it; the margins of both mandibles are sharply denticulated; the weak flat foot, which is placed very far back, has the centre toe as long as the tarsus; the hind toe is well developed, and in some species furnished with a membranous lobe; the claws are weak; in the moderate-sized, narrow, and pointed wing the second quill is the longest; the short broad tail is composed of from fourteen to twenty feathers, and is either rounded or pointed at its extremity. The plumage, which is rich, smooth, and thickly interspersed with down, varies in colour according to the sex or age of the bird; that of the male is more or less brilliant, and that of the female of comparatively sombre hue. The members of this family, regarded generally, are to be met with in every climate; the number of species is, however, greater in warm than in cold latitudes, while on the contrary in northern regions individuals of the same species swarm in immense numbers. Ducks frequent both fresh and salt water, being sometimes met with on mountain lakes to a considerable elevation; at the approach of winter they migrate to southern latitudes, often in incalculable hosts. In the extent of their migrations some species emulate the Swallow itself, while others wander no further than is absolutely necessary in order to obtain food. These migrations are generally commenced at sunset; towards midnight the birds alight upon some expanse of water, and after resting for a few hours recommence their journey in the early morning. Their flight is
