The Yahgan was built for the climate where he was found. He was in one respect like the whale that lived in the waters about him. He had a coat of fat under his skin that was very much better for him than the best of flannels and blankets. Besides, he had a custom that at once protected him from the cold and rendered him offensive to his white discoverers. He greased himself all over frequently with any oil at his command, and that is a custom worth remembering by people who may be cast away or lost in cold climates. Had the early explorers imitated instead of despised the Yahgan, they would have had fewer tales of suffering to tell. In these later years, sporting men of the United States have learned that when about to enter long-distance swimming matches they can endure the cooling effects of a race through the water much better if they coat themselves thickly with some such grease as vaseline. The Yahgan used whale oil as we use vaseline. The explorers spoke of his "filthy greasy skin," but the scientific sporting man of New York now imitates the Yahgan, even though vaseline gathers during a swim any flotsam that comes handy by. The Yahgan was "shelterless and naked in a land of fierce and freezing storms," but he did not freeze; he did not even shiver in ordinary Cape Horn weather. However, one can understand why the explorers did not perceive the real condition of the Yahgan. They were cold in spite of thick flannels, and it was but natural that they should judge others by themselves. But one cannot so easily understand how the explorers fell into such errors as they did about the ingenuity and the mechanical skill of the native. The results of Yahgan handicraft were everywhere visible. He could not make either a good house or a broadcloth suit. In his hands a white man's coat was ripped to pieces and the strips used for decorations. But there were his canoes and his weapons--especially his canoes. The Yahgan boats are mentioned slightingly, if at all, by nearly every traveller who has visited the region. "The boats are unwieldy and logy, and the Indians seem to have no knack of propelling them at any sort of speed," says a latter-day writer, who saw a canoe of the kind in the Straits of Magellan. This was the writer's judgment in the matter. But along with his judgment he gave the dimensions of the boat. It was "about twenty-five feet long, four feet wide, and three feet deep, with comparatively sharp ends." The facts as I saw them are so, save that the ends seemed to me to be extremely sharp.
