Their potro boots (fig. 5) or buskins are made from the skin of horse's hock, and occasionally from the leg of a large puma, drawn on up to the knee and fastened round the foot. It is thus worn for a day or two until the boot has taken the shape of the foot, when the leather is cut at the toes and sewn up to fit. When the sole is worn, or in very wet or snowy weather, hide overshoes are worn besides, and the footprints thus made are really large enough to convey the idea of giants' feet, and partly explain the term 'Patagon,' or large feet, applied to these Indians by the Spanish discoverers. The boots are rarely put on in camp for economical reasons, though turning out barefoot in the frozen grass at daylight is unpleasant even to a Tehuelche. But the material of the boot would soon wear out if used for walking. In riding they are secured by garters, either gay coloured woven bands, or, which is _de rigueur_ for chiefs, of hide, with massive silver buckles. Although the usual head-dress of the men is simply a coloured fillet to confine the hair, yet sometimes, and especially on state occasions, hats, if procurable, are indulged in. Old Orkeke frequently wore a felt wideawake, which was, on returning from hunting, carefully put up by his thoughtful spouse.
