Thus commenced a population likely to be of great service to shipping, particularly as they make excellent sailors, and excel as headsmen in whalers, where the keenness of their half-savage eyes, and their dexterity in throwing the spear, render them most formidable harpooners. The young half-castes I saw were very interesting, having a ruddy dark complexion, with fine eyes and teeth. On Preservation, and the islands in the neighbourhood, there were twenty-five children; among whom were some fine-looking boys. Had the survey just been commenced I should have taken one of them in the Beagle. Their fathers, I am happy to say, give them all the instruction in their power: many can read the Bible, and a few write. The common native belief in the transmigration of souls did not extend, I was glad to find, beyond the mothers, whom nothing could induce to think otherwise. When we were at Preservation Island, there was a young woman on her way, in company with her father, to Port Dalrymple, to be married to a European; and I afterwards learned from the clergyman there, that he had not for some time seen a young person who appeared to be so well aware of the solemn vow she was making. MUTTON BIRDS. The principal trade of the Straitsmen is in the feathers of mutton birds (Sooty Petrels) which annually visit the islands, between the 15th and 20th of November, for the purposes of incubation. Each bird lays only two eggs, about the size of that of a goose, and almost as good in flavour. The male sits by day and the female by night, each going to sea in turn to feed. As soon as the young take wing they leave the islands. Their nests are two or three feet underground, and so close that it is scarcely possible to walk without falling. The collection of the eggs and birds, which is the business of the women, is frequently attended with great risk, as venomous snakes are often found in the holes. When the sealers wish to catch them in large quantities they build a hedge a little above the beach, sometimes half a mile in length. Towards daylight, when the birds are about to put to sea, the men station themselves at the extremities, and their prey, not being able to take flight off the ground, run down towards the water until obstructed by the hedge, when they are driven towards the centre, where a hole about five feet deep is prepared to receive them; in this they effectually smother each other. The birds are then plucked and their carcasses generally thrown in a heap to waste, whilst the feathers are pressed in bags and taken to Launceston for sale.* The feathers of twenty birds weigh one pound; and the cargoes of two boats I saw, consisted of thirty bags, each weighing nearly thirty pounds--the spoil of eighteen thousand birds! I may add, that unless great pains are taken in curing, the smell will always prevent a bed made of them from being mistaken for one composed of the Orkney goose feathers. Some of the birds are preserved by smoking, and form the
