HARRINGTON ] DESCRIPTION OF THE ARTIFACTS 75 
317.5 mm. wide at the fracture, and 107.9 mm. high. The coneavity is 50.8 mm. 
deep and 177.8 mm. diameter, the fracture traversing probably its maximum 
depth. The edges are rounded and the bottom is the original surface of the 
rock. (Pl. 6, a.) 
Entire mortar of somewhat friable gray sandstone. 180.9 mm. diameter, 
107.9 mm. high. The outside meets the concavity, forming quite a sharp edge. 
The coneavity is 53.9 mm. diameter. The bottom is rounded, there being no 
flat portion. Although the two halves were found in the same pit they differ 
considerably in color, one half being much darker than the other. 
Fragment consisting of perhaps one-half of an oblong-shaped bowl of buffish 
gray sandstone, somewhat friable, 184.1 mm. long, 161.9 mm. wide, 120.6 mm. 
high. The concavity is 114.3 mm. long in the present fractured condition of 
the specimen, 98.4 mm. wide, 69.8 mm. diameter. The rim was evidently flattish, 
but there is a long fracture off the lower edge of the rim. The bottom is flat 
and about 120.6 mm. wide, but rounds gradually into the sides. 
Entire bowl of light greenish gray sandstone, fine textured; 209.5 mm. 
diameter, 114.3 mm. high. The rim is rounded. The concavity is 103.1 mm. 
diameter. The bottom is quite flat and its extent is well defined, it being 
about 123.8 mm. diameter. There is a fracture off nearly half of the rim. The 
bottom has been knocked out, leaving a hole 42.8 mm. diameter, with edges only 
14.2 mm. thick. The thinness of the bottom would indicate in the case of this 
specimen at least that it may have been broken through by use. 
Fragmentary mortar of hard gray sandstone. The fragment measures 180.9 
mm. diameter and sits 114.3 mm. high, which is the original height. The rim 
is rounded but remains intact only in places. The concavity is 93.6 mm. 
diameter. About one-third of the mortar is broken away, the break being old 
and encrusted as is the rest of the specimen. 
Fragment of mortar of very coarse, friable buff gray sandstone. The frag- 
ment is 168.2 mm. diameter, 133.8 mm. high. The concavity is 61.9 mm. 
diameter. Little if any of the rim remans intact but it was doubtless 
rounded. 
Entire mortar of hard gray sandstone, smooth textured; 228.6 mm. diameter, 
95.2 high. The rim is rounded, and there is a rim fracture extending a quarter 
of the circumference, the missing fragment having been found and stuck in 
place. The concavity is 79.8 mm. diameter. A hole 38.1 mm. in diameter has 
been knocked out of the bottom, the thickness of the bottom being only 15.8 
mm. The cleavage slants from the inside edge of the hole outward, indicating 
that the hole was produced by a blow from the inside, probably in the course of 
use. (PI. 4, e.) 
Fragmentary mortar of gray sandstone with a somewhat greenish caste, 
rather soft and friable; 355.6 mm. diameter, 163.5 mm. high. Enough of the 
bottom is left to determine the original height. The rim is rather sharply 
rounded and is more or less intact. The concavity is 96.8 mm. diameter. The 
hole in the bottom is 158.7 mm. long and 82.5 mm. wide, and the thickness of 
the bottom is 68.2 mm. The bottom is rounded uniformly and evidently 
contains no flat area. 
Entire mortar of light gray sandstone. The stone is very sandy in content 
but not friable, 247.6 mm. long, 227 mm. wide, 69.8 mm. high. The edges are 
very irregular but are natural, except at the most acute corner, which has been 
pecked. The rim is broad and flat. The concavity is at the center of the top 
surface and measures 107.9 mm. diameter and only 22.2 mm. deep. The bottom 
is somewhat flat and is the original surface. Although this specimen was 
possibly used as a hopper mortar, there is no proof that it was in the shape of 
asphalt adhering to the rim. (PI. 5, b.)
