78 EXPLORATION OF BURTON MOUND [ETH. ANN, 44 
Entire hopper mortar of buff sandstone with somewhat greenish caste, rather 
friable; 320.6 mm, long, 292.1 mm. wide, 130.1 mm. high. The rim is intended 
to be somewhat flat. The concavity is 244.4 mm. diameter and 49.2 mm. deep. 
There are stains of asphalt for the attachment of the basket hopper all along 
the rim. The edges are rounded, the bottom flat. 
Entire hopper mortar of coarse greenish sandstone; 215.9 mm. diameter, 
123.8 mm, high. Rim rounded with asphalt almost everywhere adhering. The 
coneavity is 22.2 mm. diameter. The edges are rounded, the bottom is pecked 
flat. 
Entire hopper mortar of very coarse and friable greenish gray sandstone; 
2444 mm. diameter, 139.7 mm. high. The rim is intended to be flattish and 
has sparse flecks of asphalt adhering. The edges are rounded, the bottom 
flat. 
Entire hopper mortar of somewhat dark buff colored sandstone, not friable; 
285.7 mm, diameter, 153.9 mm, high. The rim is flattish, and has abundant 
traces of asphalt. The concavity is 215.9 mm. diameter and 55.5 mm, deep. 
The edges are rounded, the bottom is flat. 
Entire hopper mortar of light gray sandstone; 215.9 mm. diameter, 95.2 mm. 
high. Edge rounded with traces of asphalt which show in part the exact posi- 
tion of the lower edge of the basket by a bare streak between two bands of 
asphalt. The concavity is only 22.2 mm. diameter. The edges are rounded, 
the bottom is also somewhat rounded. (PI. 7, 6.) 
Entire hopper mortar of brownish gray sandstone, fine textured and hard; 
295.2 mm. long, 127 mm. high. The rim is pecked flat in places, in other places 
rounded. It is much blackened from former asphalt and there are traces from 
the asphalt far down the sides of the mortar. The concavity is 58.7 mm. 
diameter. The edges are rounded, the bottom somewhat rounded. (PI. 7, d.) 
Entire hopper mortar of buff gray sanstone, very friable and coarse; 247.6 
mm. diameter, 133.3 mm. high. Rim flattish and traces of asphalt remain in 
two places. Concavity 31.7 mm. diameter. The concavity has a ring of dis- 
coloration as if some liquid had at some time stained the inner’ surface. The 
outer edge is rounded and shows two straight fractures. The bottom is 
rounded. 
Somewhat fragmentary hopper mortar of gray sandstone with brownish cast 
in places, friable and very coarse; 260.3 mm. diameter, 120.6 mm. high. The 
rim was evidently originally squared, but has been broken away for the most 
part. In one section, 171.4 mm. long, asphalt still adheres, suggesting the use 
of this specimen as a hopper mortar. The concavity is 93.6 mm. diameter, and 
at its bottom a hole has been broken out 66.6 mm. diameter. The outside and 
bottom of the specimen are rounded. The specimen was found in two halves. 
Fragmentary mortar of greenish gray sandstone, somewhat friable, probably 
a portion of a former bowl of larger size which has been used secondarily as a 
hopper mortar, as indicated by the aspahlt adhering to the rim; 222.2 mm. 
long, 200 mm. wide, 165.1 mm. high. The concavity is 57.1 mm, diameter. 
The longest edge consists in part of the old rim, all other edges are fractures. 
The corners of the edges have been pecked away somewhat and asphalt has 
been applied around the periphery of the concavity for the attachment of a 
basket. 
e Fragment of a hopper mortar, consisting of more than half the original 
mortar. Greenish gray sandstone, somewhat friable, 244.4 mm. diameter, 79.3 
mm. high. Rim squared with abundant traces of asphalt, which extends to the 
concavity and to the outside of the specimen. The concavity is 50.8 mm. 
diameter. Edges rounded, bottom somewhat flat.
