In Greenland, Iceland, Spitzbergen, Lapland, and some parts of the coast of Norway, the eiders flock together, in particular breeding places, in such numbers, and their nests are so close together, that a person in walking along can hardly avoid treading upon them. The natives of these cold climates eagerly watch the time when the first hatchings of the eggs are laid: of these they rob the nest, and also of the more important article, the down with which it is lined, which they carefully gather and carry off. These birds will afterwards strip themselves of their remaining down, and lay a second hatching, of which also they are sometimes robbed; but, it is said, that when this cruel treatment is too often repeated, they leave the place, and return to it no more. The eider birds build their nests on little islands, not far from the shore, and sometimes even near the dwellings of the natives, who treat them with such kindness and circumspection as to make them quite tame. In the beginning of June they lay five or six eggs, and it is not unusual to find from ten to sixteen eggs in one nest, with two females, who agree remarkably well together. The whole time of laying continues six or seven weeks, during which time the natives visit the nest, for the purpose of taking the down and eggs, at least once a week. They first carefully remove the female, and then take away the down and part of the eggs; after which she lays afresh, covering her eggs with new down plucked from her breast; this being taken away, the male comes to her assistance, and covers the eggs with his down, which is left till the young are hatched. One female, during the whole time of laying, generally gives half a pound of down. The down from the dead birds is accounted of little worth, having lost its elasticity. There are generally exported fifteen hundred or two thousand pounds of down on the company’s account, exclusive of what is privately sold.—The young ones quit the nest soon after they are hatched, and follow the female, who leads them to the water, where, having taken them on her back, she swims with them a few yards, and then dives, and leaves them floating on the water: in this situation they soon learn to take care of themselves, and are seldom afterwards seen on the land, but live among the rocks, and feed on insects and sea-weed. * * * * * “In my way hither,” says Major C., “I measured the flight of the eider ducks by the following method; viz., on arriving off Duck Island, six miles distant from Henly Tickle, I caused the people to lay on their oars; and when I saw the flash of the guns, which were fired at a flock of ducks as they passed through the latter, I observed by my watch how long they were in flying abreast of us. The result of very many observations, ascertained the rate of their flight to be ninety miles in an hour.” * * * * *
