152 CERTAIN SAND MOUNDS OF 



were three spindle-shaped "sinkers" rimmed at the end for suspension, and four 

 beads of shell from 1 to 1*3 inches in length. 



Separately on the base were five "celts" of shell from 2 - 5 to 6 inches long; 

 five shell " sinkers" from 3 to 4 - 5 inches in length; one shell bead with a maximum 

 diameter of 1*5 inches, and the columella of a marine univalve worked at the ex- 

 tremities and smoothed at the junction of the whorls (Fig. 24).

In association on the base, in one of the rare pockets of red sand met with in 

 the mound, were five shell beads ranging in maximum diameter from about "3 to 

 •75 of an inch. 



Three feet from the surface was a gouge wrought from the shell of Fulgur. 



Five drinking cups made from Fulgur perversum were met with during the 

 investigation. One, imperforate, lay five feet from the surface; the others, from or 

 near the base, showed the usual perforation below the shoulder opposite the aper- 

 ture. One of these cups lay within a larger specimen. 



An elliptical ornament of shell 3"5 inches in length was found on the base, 

 and a shell gouge was exhumed 3 feet from the surface. 



For fuller details as to many of these interesting types, the reader is referred 

 to Professor Holmes' exhaustive paper "Art in Shell," Report of Bureau of Eth- 

 nology, 1880-1881. 



BONE. 



On the base of the mound was an implement of bone, pointed at one end. 

 having the articular portion at the other. 



COPPER. 



The discovery of copper in the Tick Island Mound was a matter of surprise 

 and congratulation, after much repeated and unsuccessful search. 



Six inches from the surface, with human remains, was a centrally perforated 

 disc of copper 3"2 inches in diameter, encircled near the margin by a series of small 

 indentations forming projections on the other side. 



This ornament is shown in Fig. 25 with section removed for analysis, the 

 result of which will be found included in the Note on copper in the latter part of 

 this Report
