HARRINGTON ] DESCRIPTION OF THE ARTIFACTS id 
Entire mortar of greenish gray sandstone, somewhat friable; 333.3 mm. long, 
193.6 mm. high. The rim is squared and varies from 22.2 mm. to 19 mm. in 
width. The concavity is 149.2 mm. diameter and has a hole at its base 114.3 
by 88.9 mm. The thickness of the bottom is 34.9 mm. The outside and bottom 
are rounded. This bowl was discovered by Mr. Charles T. Hall, inverted on 
the beach at low tide at the foot of Bath Street, south of the Burton Mound, in 
1871. 
HOPPER MORTARS 
A ring of asphalt or traces of such a ring adhering to the rim of 
several mortars proved that such vessels had been augmented by a 
basketry rim. Such mortars varied from mere slabs to deeply worn 
bowls. 
Entire hopper mortar of buff colored and hard sandstone, 247.6 mm. greater 
diameter, 204.7 mm. lesser diameter, 69.8 mm, high. The mortar consists of a 
slab, the edge of which is very roughly rounded. The top surface is not cupped 
at all but shows a band of asphalt averaging 50.8 mm. in width around 
its edge, which was used for sticking the basketry rim to the stone. The as- 
phalt that remains is as much as 7.9 mm. thick in places. The bottom is the 
former surface of the boulder and most of its surface is flecked over with 
asphalt. (Pl. 7, e.) 
Entire hopper mortar of gray sandstone, 187.8 mm. diameter, 98.4 mm. high. 
Concavity of the upper surface is only 7.9 mm. diameter and a band of asphalt 
averaging 44.4 mm. in width runs around its periphery. The edge of the mor- 
tar consists of four major cleavages. The bottom is flat and half of it has 
been pecked to its present shape, while the other half is the original surface of 
the rock. (PI. 7, ce.) 
Entire hopper mortar of gray sandstone, somewhat friable; 282.5 mm. long, 
212.7 mm. wide, 111.1 mm. high. The rim is flattish and shows only patches 
and stains of the asphalt which formerly adhered. The concavity is 180.9 
mm. long, 165.1 mm. wide, and only 17.4 mm. diameter, and shows pecking on 
its walls, which would indicate that the specimen had not been used much for 
pounding. The outside edges are naturally squared, being pecked into shape 
only in a place or two. The bottom is very flat, consisting of the original 
surface. 
Entire hopper mortar of gray and somewhat friable sandstone; 273 mm. 
diameter, 139.7 mm. high. The rim is rounded and a band of asphalt adheres 
to it in places varying in width from 22.2 mm. to 25.4 mm. The concavity is 
only 15.8 mm. diameter. The outer sides and bottom are rounded and consists 
of the original surface. 
Entire hopper mortar of very green-colored fine-textured sandstone; 288.9 
mm. diameter, 95.2 mm. high. The rim is flattish. The coneavity is 190.5 mm. 
diameter and only 36.5 mm. deep. Flecks of asphalt on the surface of the 
rim indicate the former use of the specimen as a hopper mortar. The edges 
are roughly rounded in places by pecking. The bottom is flat and consists of 
the old surface. 
Entire hopper mortar of somewhat greenish gray sandstone, somewhat 
friable; 241.3 mm. long, 190.5 mm. wide, 95.2 mm. high. The rim is rounded 
and there adheres to it a band of asphalt averaging perhaps 25.4 mm. in 
width. The concavity is 30.1 mm, diameter. The edges are rounded at places 
with the help of pecking. The bottom is somewhat flat. (Pl. 7, a.)
