NO. II PUEBLO RUINS IN ARIZONA HAURY AND HARGRAVE 23 



Polishing pebbles. — Figures e and /, plate 6, figure i, show two 

 typical polishing pebbles used in the surfacing of pottery. Both have 

 the very smooth facets which result from long use. 



Perforated sandstone plates. — For the two objects represented in 

 plate 6, figure i, g and //, we can suggest no definite use. Both are 

 made of sandstone not exceeding | inch in thickness ; both are carefully 

 smoothed. Figure g is 6| by 5I inches and has rounded corners as well 

 as trimmed edges. Along one edge there are three perforations, 

 drilled from both sides of the plate. Specimen h is rounded, 6| inches 

 in longest dimension. It has but a single perforation placed ^ inch 

 in from the short straight edge. 



These objects are not greatly dissimilar to perforated boiling stones 

 which resemble large pendants frequently found in ancient sites in 

 southern California.^ Boiling stones of this type are heated in the 

 fire and suspended in vessels containing liquids for cooking purposes. 

 Both of the specimens represented here show the effects of contact 

 with fire, but whether the result from their use or from the burning 

 of the rooms in which they were found, cannot be determined. The 

 custom of using boiling stones, however, is a trait quite foreign to 

 Pueblo culture ; hence, their use as such must be questioned. 



Loom block. — A single loom block was encountered in one of the 

 living rooms. It is made of a soft friable sandstone and measures 

 about 10 inches in height by 7 inches in width. The base and one side 

 are entirely flat, while the rest of the block is more or less of rounded 

 form. In the flat side near the top is a small depression less than an 

 inch in depth which engaged one end of a stick or rod which formed 

 a part of a loom. Similar objects found in old Hopi " and present- 

 day Hopi kivas are usually shaped into the forms of rectangiflar 

 blocks with the depressions in one end. 



Potter's kneading slab. — A sandstone slab, not unlike those used 

 at Zufii ' at the present time by potters for kneading clay after the 

 ingredients have been ground and mixed, is shown in plate 6, figure 2. 

 It was found with a quantity of raw clay, yellow ochre, and a collection 

 of sherds which had been gathered for pulverization to form tempering 

 material. The slab is rectangular in outline, 33 by 17 inches. Its 

 edges are chipped and pecked to a rough finish and the working surface 

 bears two shallow worn depressions which still show traces of clay.
