Milling Rooms
There are several rooms in Cliff Palace which appear to have been given up solely to the operation of grinding corn. The mills are box-like structures, constructed of slabs of stone set on edge, each containing a slanting stone called a metate, from which the mill is called by the Hopi the metataki, or "metate house." The following description of a metataki in pueblos seen by Castañeda in 1540 applies, in a general way, to the small milling troughs in Cliff Palace:
One room is appointed for culinary purposes, another for the grinding of corn; the latter is isolated [not so in Cliff Palace] and contains an oven and three stones [one, two, three, or four in Cliff Palace], cemented finely together. Three women sit [kneel] before these stones; the first crushes the corn, the second grinds it, and the third reduces it quite to a powder.
In grinding corn, which was generally the work of the girls or young women, the grinder knelt before the metataki and used a flat stone, which was rubbed back and forth on the metate. The corn meal thus ground fell into a squarish depression, made of smooth stones, at the lower end of the metate. Commonly the corners of this receptacle for the meal that had been ground were filled in with clay, and on each side of the metate were inserted fragments of pottery, which rounded the corners and made it easier to brush the meal into a heap. In room 92, where there are four metates, occupying almost the whole milling room, there are upright stones on the side of the wall, back of the place where the women knelt, against which they braced their feet.
Most of the grinding boxes were destroyed, but those in the Speaker-chief's house and others west of kiva V, especially the latter, were still in good condition, the metates being in place. Evidences of former metatakis were apparent in the floor of several other rooms, as in a room back of kiva K. It is evident from the number of metates found in Cliff Palace that several milling rooms, not now recognizable, formerly existed, and it is probable that every large clan had its own milling room, with, one or more metatakis, according to necessity. Although, many metates without metatakis occur in Cliff Palace, that in itself is not evidence that they were moved from place to place by the inhabitants. These milling rooms were apparently roofed, low, and one-storied, possibly in some instances open on top, but generally had a small peephole or window for the entrance of light or for permitting the grinders to see passers-by.
