We may conclude, then, that so long as the Pueblo ancestry were semi-nomadic, basketry supplied the place of pottery, as it still does for the less advanced tribes of the Southwest, except in cookery. Possibly for a time basketry of this kind served in place of pottery even for cookery, as with one of the above-mentioned tribes, the _Ha va su paí_ or Coçoninos, of Cataract Cañon, Arizona. These people, until recently, were cut off from the rest of the world by their almost impenetrable cañon, nearly half a mile in depth at the point where they inhabit it. For example, when I visited them in 1881, they still hafted sharpened bits of iron, like celts, in wood. They had not yet forgotten how to boil food in water-tight basketry, by means of hot stones, and continued to roast seeds, crickets, and bits of meat in wicker-trays, coated inside with gritty clay. (See Fig. 501.) The method of preparing and using these roasting-trays has an important bearing on several questions to which reference will be made further on. A round basket-tray, either loosely or closely woven, is evenly coated inside with clay, into which has been kneaded a very large proportion of sand, to prevent contraction and consequent cracking from drying. This lining of clay is pressed, while still soft, into the basket as closely as possible with the hands and then allowed to dry. The tray is thus made ready for use. The seeds or other substances to be parched are placed inside of it, together with a quantity of glowing wood-coals. The operator, quickly squatting, grasps the tray at opposite edges, and, by a rapid spiral motion up and down, succeeds in keeping the coals and seeds constantly shifting places and turning over as they dance after one another around and around the tray, meanwhile blowing or puffing, the embers with every breath to keep them free from ashes and glowing at their hottest. That this clay lining should grow hard from continual heating, and in some instances separate from its matrix of osiers, is apparent. The clay form thus detached would itself be a perfect roasting-vessel. POTTERY SUGGESTED BY CLAY-LINED BASKETRY. This would suggest the agency of gradual heat in rendering clay fit for use in cookery and preferable to any previous makeshift. The modern Zuñi name for a parching-pan, which is a shallow bowl of black-ware, is _thlé mon ne_, the name for a basket-tray being _thlä´ lin ne_. The latter name signifies a shallow vessel of twigs, or _thlá we_; the former etymologically interpreted, although of earthenware, is a hemispherical vessel of the same kind and _material_. All this would indicate that the _thlä´ lin ne_, coated with clay for roasting, had given birth to the _thlé mon ne_, or parching-pan of earthenware. (See Fig. 502.)
