It is an interesting fact in medical science, that the Onas a long time ago discovered a sure and speedy remedy for the chief ill that Indians are heir to through association with the whites, in a decoction of the thorny bush that grows on the plains, and is known to science as _berberis_. THE ALACULOOFS. One tribe inhabiting the Cape Horn region remains to be mentioned. It is found exclusively among the islands west of Punta Arenas and Cockburn Channel. I wish that I had the facts for describing it. This is the tribe that has been mentioned so often by people passing through the Strait of Magellan. They were invariably called Fuegians by all who saw them, and were described in terms to indicate that they are the most wretched, the most filthy, the most degraded, and the most terrible beings on earth. As I said, I should like to know the facts, for these descriptions, except as to their appearance to a casual observer, are valueless. The Yahgans were described in equally severe terms. On the beach at Punta Arenas the citizens pointed to a dismantled sloop that was hauled up to be sold at auction. She was a ragged thing, say twenty feet long. There was a large hatch amidships with splashes of blood on it, and a number of holes where Winchester bullets had come up through the boards from below. She bore the name of _Teresina B._ With four men as a crew and a cargo of tobacco, rum, old clothes, matches, hard bread, cheap cutlery, etc., she had sailed away from Punta Arenas for a trading voyage to the Alaculoof Indians. Her crew were bound, in a small way, on a voyage like that of the great Magellan; they meant to get valuables in return for things of little value. When about forty-five miles south of the town they sent a man ashore in a small boat for wood and water, and that was the last ever seen of the man. The next morning three canoes loaded with Indians came in view. Thereat one of the white sailors urged the sloop's captain to make the Indians stay away, or at least to permit but two or three men in one canoe to approach at a time. To this the captain replied that the Indians were Christian Yahgans from Ushuaia, and just what were wanted. [Illustration: ALACULOOF INDIANS.] "Very well," said the sailor, "you may do the trading. I'll go down below." He went below and drew the hatch almost to its place and fastened it. The captain and the other sailor remained on deck to trade, the sailor sitting over the companionway. As the Indians drew alongside it appeared that they were Alaculoofs instead of Yahgans, and they dropped their paddles, and, grasping their harpoons, attacked the whites. Both white men were badly wounded by the first harpoons thrown. The sailor fell into the cabin, his head badly cut, and all life apparently gone. The captain had life enough to try to crawl down, but the Indians were on him, and he was harpooned to death.
