The third tribe is a race of giants. They are called Onas by their neighbours, the Yahgans. The Onas have, thus far, evaded all efforts at civilisation, have refused missionaries, and have, to the present time, with good reason, persistently mistrusted white men. They have in consequence remained unknown. The homes of the Onas are on the main island of Tierra del Fuego. For centuries they have fought to keep this as their preserve; but the Yahgans have been allowed to pitch their tents on the southern coastal fringe along Beagle Channel. In a like manner the Alaculoofs have been permitted to use the shore-line of the west. Neither the Yahgans nor the Alaculoofs, however, nor white men, until very recently, have dared venture into the interior. The great prairies of the north and the mountain forests of the middle of the island, with the still unknown lakes, have been guarded as hunting-ground exclusively for the Onas. The island is nearly as large as the State of New York. The boundary-line of Chile and Argentina, running from north to south through the centre of the island, gives each republic a nearly equal share of the country. Gold has been found in the sands along the beach of various parts of the land. This is being mined with considerable success. The pampas of the north and a part of the southern ground have proved to be some of the best sheep-farming country of the world. The gold-diggers and the sheep-farmers have thus re-discovered Tierra del Fuego as they have Patagonia. The mining camps and the wire fences are crowding the once ruling race of Onas into the useless forest-covered lowlands and the ice-covered highlands of the interior, where they must either starve or freeze or perish at the hands of Caucasian invaders. The old happy hunting-ground of the Ona has gone the way of all other Indian homes; but he has fought bravely for it, and he will continue to do so until the last skeleton is left to bleach on the wind-swept pampas.
