[Illustration: 49. EIDER-DUCK.] Mr. Shepherd thus describes his visit to Vigr, in the Isafjardardjup, one of the head-quarters of the eider-duck in the north of Iceland: “As the island was approached, we could see flocks upon flocks of the sacred birds, and could hear their cooings at a great distance. We landed on a rocky wave-worn shore, against which the waters scarcely rippled, and set off to investigate the island. The shore was the most wonderful ornithological sight conceivable. The ducks and their nests were everywhere in a manner that was quite alarming. Great brown ducks sat upon their nests in masses, and at every step started up from under our feet. It was with difficulty that we avoided treading on some of the nests. The island being but three-quarters of a mile in width, the opposite shore was soon reached. On the coast was a wall built of large stones, just above the high-water level, about three feet in height, and of considerable thickness. At the bottom, on both sides of it, alternate stones had been left out, so as to form a series of square compartments for the ducks to make their nests in. Almost every compartment was occupied; and, as we walked along the shore, a long line of ducks flew out one after another. The surface of the water also was perfectly white with drakes, who welcomed their brown wives with loud and clamorous cooing. When we arrived at the farmhouse we were cordially welcomed by its mistress. The house itself was a great marvel. The earthern wall that surrounded it and the window embrasures were occupied by ducks. On the ground, the house was fringed with ducks. On the turf slopes of the roof we could see ducks; and a duck sat in the scraper. “A grassy bank close by had been cut into square patches like a chessboard (a square of turf of about eighteen inches being removed, and a hollow made), and all were filled with ducks. A windmill was infested, and so were all the outhouses, mounds, rocks, and crevices. The ducks were everywhere. Many of them were so tame that we could stroke them on their nests; and the good lady told us that there was scarcely a duck on the island which would not allow her to take its eggs without flight or fear. When she first became possessor of the island, the produce of down from the ducks was not more than fifteen pounds’ weight in the year, but, under her careful nurture of twenty years, it had risen to nearly one hundred pounds annually. It requires about one pound and a half to make a coverlet for a single bed, and the down is worth from twelve to fifteen shillings per pound. Most of the eggs are taken and pickled for winter consumption, one or two only being left to hatch.”
