canvas-back could scarcely have been more so. These ducks are summer visitors to our lake. Unlike others of their family, they build nests in trees. They are said to be one of the two most beautiful species in the world, the other being the Mandarin Duck of China. Ours are chiefly confined to the fresh waters of the interior, being seldom found on the sea-shore. They are said frequently to build in the same tree for several seasons. Mr. Wilson gives a pleasing account of a nest he had seen on the banks of the Tuckahoe River, New Jersey:—“The tree was an old grotesque white oak, whose top had been torn off by a storm. In this hollow and broken top, and about six feet down, on the soft, decayed wood, lay thirteen eggs, snugly covered with down, doubtless taken from the breast of the bird. The eggs were of the highest polish, fine in the grain, greatly resembling old polished ivory. This tree had been occupied, probably by the same pair, for four successive years in breeding-time; the person who gave me the information, and whose house was within twenty or thirty yards of the tree, said that he had seen the female, the spring preceding, carry down thirteen young, one by one, in less than ten minutes. She caught them in her bill by the wing, or the back of the neck, and landed them safely at the foot of the tree, when she afterward led them to the water. Under this same tree, at the time I visited it, a large sloop lay on the stocks, nearly finished; the deck was not more than twelve feet distant from the nest, yet notwithstanding the presence and the noise of the workmen, the ducks would not abandon their old breeding-place, but continued to pass out and in, as if no person had been near. The male usually perched on an adjoining limb, and kept watch while the female was laying, and also often while she was
