The stone used by the Oraibians for making piki is from a sandstone quarry near Burro Springs. It is about twenty inches long by fourteen broad, and is three inches thick. The upper surface is first dressed by means of stone picks, and is polished by a hard rubbing-stone, and then finally treated with pitch and other ingredients until its surface is as smooth as glass. It is mounted on its two long edges by upright slabs, so that it stands about ten inches from the level of the floor, the floor itself being usually excavated to a depth of two or three inches beneath the stone. At a height of about four feet above this primitive griddle is a large rectangular hood which is extended above the roof in the form of a chimney made of bottomless pots, one resting on the other. Kneeling in front of the stone and supporting her body with her left arm, the woman coats the stone with the thin batter of corn and water with the fingers of her right hand. After a few seconds' time she lifts the waferlike sheet from the stone and transfers it to a mat which is made for this special purpose. For some time the piki remains soft and pliable, and while in this condition she rolls or folds the sheets according to her custom--some folding, others rolling it. It is a curious sight on the feast days of certain ceremonies to see women gathering from all quarters of the village at an appointed house, each carrying a tray heaped high with rolls of this paper bread.
