excreta from both. After watching the birds, however, for some days, it was discovered that, with

the view of deceiving the men, they had only made a pretence of having their nest in the hole above mentioned, and that their real residence was another much larger excavation, in the joint occupation of a bitch-fox and a badger. This second hole being carefully watched, it was seen that the badger was in the habit of walking in and out of his abode, which was subsequently found to be ten feet deep, without troubling himself at all about his feathered visitors, whose footmarks were traceable to a depth of seven feet. There were, however, other holes belonging to the same den, through which the fox was also in the habit of passing. The ground before these entrances was trampled smooth by the feet of the Ducks, and as clearly impressed with the footmarks of the fox. On perceiving this, Grömelbein concealed himself behind a wall in such a manner as to be able to watch all their proceedings, nor had he long to wait before he saw the sly Sheldrakes paying their accustomed visit to the labourers and the sand-hill above mentioned; after which, flying close to the ground, they came to the real nesting-place, when, after carefully looking around them, they walked into the fox-hole as quietly and unconsciously as Ducks in a farmyard would go to their roosting-place. There they remained about half an hour, when they again made their appearance, climbed hastily to the top of the hill beneath which the den was situated, and finding, as they thought, the coast clear, flew off to the meadows.

In the Island of Sylt and others off the coast of Schleswig, the inhabitants construct artificial burrows, covered with movable lids, near which at the proper season they place quantities of broom and moss, so that the coming birds may find everything ready. These consequently take up their abode in the prepared burrows without the slightest scruple, and that sometimes quite close to the houses of their owners; nay, they at length become so familiarised with their keepers that they may be said to be in a state of semi-domestication. In these burrows the females, if not disturbed, will lay from seven to twelve large, smooth, white, thin-shelled eggs; but if the eggs are gradually taken from the nest, as they are at Sylt, the females will go on laying till they have laid twenty or thirty. When the mother bird begins to sit, she carefully surrounds her eggs with down, and when she leaves her nest covers them with the same warm material. After the lapse of about twenty-six days, the young make their appearance, and soon follow their mother to the neighbouring moors, generally stopping, however, to have a swim in a pond of fresh water that is found on the road thither. To the inhabitants of Sylt and other islands in the North Sea, it appears, therefore, that the Sheldrakes are objects of considerable attention. The eggs serve as important additions to their table; and the down from their nests, scarcely inferior to that of the Eider, is extremely valuable. The flesh of these birds is not much esteemed, having a rancid or oily taste and a disagreeable smell; they are therefore never killed, but, on the contrary, are protected by the inhabitants of the islands they frequent.

The TREE DUCKS (Dendrocygna) form a group having a high slender body, moderately long neck, delicately-shaped head, and weak bill; the legs are long, the wings blunt, with the third and fourth quills longer than the rest; the tail is rounded at its extremity, and the plumage variegated.

THE WIDOW DUCK.

The Widow Duck (Dendrocygna viduata) has the face and throat white, shaded with reddish brown on the brow and cheeks; the back of head, nape, and sides of the neck are bright reddish brown; the sides of the breast and the back reddish olive, darkly spotted and marked; the long lower shoulder-feathers are olive-brown edged with yellowish white; the lower back, centre of tail, and entire under side below the breast are black; the sides of the body are greyish white, striped with
