He was so well treated that on returning on shore he induced several of his countrymen to visit the ships, and one of them especially behaved with so much good humour, and was so completely at his ease, that he won the regard of the voyagers. To show his gratitude, he brought them off an animal, from the skin of which, he let them understand, the robe he wore was composed. The voyagers had never seen any creature like it before, and described it as a beast which was neither mule, horse, nor camel, but partaking of all three, having the ears of a mule, the tail of a horse, and the body shaped like a camel. He was probably a guanaco or llama, commonly known as the Peruvian sheep. The Admiral, wishing to make prisoners of some of these big fellows, gave orders to his crew to secure them. Accordingly, while the poor savages were being amused with toys put into their hands, which they grasped eagerly, the Spaniards put iron shackles on the legs of two of them, persuading the men that they were fine ornaments, like the rest of the things shown them. They appeared highly pleased with the jingling sound they produced when struck together, until they suddenly found themselves hampered and betrayed, on which they began bellowing like bulls, and shouting to their god--_Setebos_--for assistance. From this Shakespeare has undoubtedly taken the name of the demon _Setebos_, introduced in the play of the "Tempest." This act of treachery was not calculated to raise the Spaniards in the opinion of the natives. One of the prisoners remained on board the Admiral's ship, while his companion was carried to another for safe keeping. In spite of this they did not object to the strangers coming among them, although they kept their women out of the way. They were all dressed like those who came on board, in the skins of beasts, and their hair was short or tied up by a string. They had apparently no fixed dwellings, but lived in huts covered with skins and supported by poles, so that they could easily be moved. They were not seen to cook their food, but ate meat raw, with a sweet root called capar, which name they applied to the ship's biscuit offered them. The only remedies they were seen to use when sick was bleeding and vomiting. The former was performed by giving a chop with an edge tool to the part afflicted, while the latter was produced by thrusting an arrow down the throat of the patient. The voyagers, ignorant and superstitious themselves, declared that they saw among the savages on shore all sorts of strange creatures of horrible forms, such as horned demons, with long shaggy hair, throwing out fire before and behind, which especially made their appearance when the natives were dying.
