MORRIS] RUINS ON THE MESAS 201 
fine grained sandstone, through which a trough has been worn by the 
incessant back-and-forth motion of the mano. It is worthy of note 
that only two metates were found in Ruin 
No. 17, where considerable quantities of corn — 4 
were stored. 
Slabs of Undecided Function—Two of 
these slabs are shown in plate 73, d and 
h. As they are more nearly rectangu- 
lar than round, it seems unlikely that 
they correspond to the round potlids ,, § Design on bowl 
from the cliffs. It is not improbable from mouth of Long Hol- 
that they served as plates or platters ae: 
upon which to stack meal cakes: or similar objects. They are 
too small and not of the right shape to have been used as doors. 
Awves and 
Hammers .— 
Two axes of ex-

manship (pl. 
73, e@ and gq) 
were found in 
Ruin No. 17%, 
besides a number of crude ones. These are made from a dark gra- 
nitic rock, such as can be found in the river gravel which caps the 
most ancient erosion rem- 
nants in the vicinity. The 
bits are brought to as keen 
an edge as I have ever seen 
on stone implements not 
made by chipping. 
The one hammer is an 
unaltered oval bowlder 
with a groove pecked about 
the middle. 
Pottery Smoother.— 
A stone with worked and 
polished surfaces, presum- 
ably a pottery smoother, 
was found in a grave at 
Ruin No. 23 (pl. 73, 6). 
Pounding Stones.— 
Three of these are 
shown in plate 73, a, c, 7. Their specific use is unknown. 
Chipped Artifacts—The best of the chipped implements gathered 
from the mesa sites are shown in plates 74 and 75. These may be

Fic. 10.—Design on bowl from mouth of Long 
Hollow.
