In the glass dish No. 13 are some pieces of charcoal which 
formed part of the layer met with in this mound. 
The small bone implements upon Tablet 20 Case B 33, were 
found in this mound, as well as some narrow and thin slips of 
copper, and some pearl beads similar to those upon Tablet 4, 
Case B 34. 
B 33. 
Upon Tablets 22 to 26 are fragments of obsidian spear-heads, 
fractured from the heat to which they have been exposed. 
Obsidian has not been found in situ nearer than Mexico ; 
flakes, and arrow- and spear-heads, of obsidian obtained from 
five of the mounds, excavated by Squiex and Davis, in the Scioto 
valley. 
Upon Tablets 27 to 30 are thin sheets of mica, cut into 
scrolls, measuring six inches in length. Upon Tablets 31 and 
32 are similar plates of mica, cut into circles two inches in 
diameter. These figures are shaped with the greatest precision ; 
the edges are perfectly smooth, as if cut with a very sharp 
instrument ; they do not exhibit the slightest irregularity, but 
are geometrically correct in outline. Each piece is perforated 
with small holes, such as could be produced with a blunt needle. 
These objects were probably used as ornaments to the dress. 
Many of the American mounds contained mica, sometimes in 
plates of considerable thickness, but usually in thin sheets with 
ragged outlines ; like the specimens in Case E 6. 
Mica does not occur in situ in the State of Ohio, but is sup- 
posed to have been obtained from the southern heights of the 
Alleghanies. 
Traces of spun thread and woven cloth were observed in 
Mound No. 9, " Clark's Work."
