_RUBBING STONES._
(Used as rubbers in grinding corn on metates.)
1-3. 1, (46506); 2, (46507); 3, (46517). Basalt.
4, (46510). Sandstone.
5, (46512). Conglomerate.
6-9. 6, (46513); 7, (46514); 8, (46515); 9, (46516). Mica schist.
10-11. 10, (46518); 11, (46529). Of hornblende schist; these are
elongate and intended to be used with both hands.
12-13. 12, (46508); 13, (46567). Quartzite metates.
14-15. 14, (46509); 15, (46511). Sandstone metates, the latter but
little used and almost flat.
16, (46551). Rubbing stone of andesite.
17-24. 17, (46555); 18, (46556); 19, (46557); 20, (46558); 21, (46561);
22, (46563); 23, (46569); 24, (46559). Small smoothing stone mostly of
quartzite, one or two only of basalt. These are bowlders weighing from
one to three pounds, rounded by natural agencies, and selected by the
natives to be used for smoothing and polishing purposes. When much
used they are worn down flat on one side, the side used being worn
off, just as the rubbing stone in the old process of preparing paint.
25-26. 25, (46519); 26, (46520). Unfinished celts of basalt.
27, (46521). Crude hoe or adze of mica schist.
28, (46522). Schist stone with groove for smoothing arrow shaft, and
hole for rounding point.
29-31. 29, (46523); 30, (46524); 31, (46525). Crude stone implements,
supposed to be used for digging.
32-34. 32, (46526); 33, (46527); 34, (46528). Very crude stone
implements, probably used for pounding.
35, (46530). Double-handled baking stone; basalt. The use of stones of
this kind will be more particularly noticed hereafter.
36, (46531). Broken rounded mortar; basalt.
37, (47532). A small, oblong, mortar-shaped vessel of lava. The width
three inches, length when unbroken was probably four and a half
inches; width of inside two inches, length probably three and
one-fourth inches, depth of cavity three-fourths of an inch. On the
portion remaining there are four feet; originally there were doubtless
six. On one side is a projection or handle similar in form and size to
the feet. 38-54. 38, (46533); 39, (46534); 40, (46535); 41, (46536);

(46566); 53, (46568); 54, (47571). Pounding or hammer stones, some
of them simple cobble stones, others with marks of slight preparation
for use by chipping off or rubbing down prominences.
55, (46540). Sandstone with smoothed surface and groove for smoothing
arrow shafts.
56-64. 56, (46541); 57, (46542); 58, (46543); 59, (46544); 60, (46545);

rubbers for metates.
69, (46988). Spear head. Basalt.
