into which a hole has been drilled at each end. This was 
found at Horse Landing, midway between the top and base — 
of the shell-heap, and was the only object found actually — 
within the shell-heap, which was clearly the work pig.. 
of the human hand. Nearly similar forms are 
figured in the plates of the Brevis Narratio, as 
forming a part of the necklace worn by the na- 
tives.* 
Fig. 8, front view; fig. 9, side view (natural 
size), represents an instrument made of shell, | 
which, from the exterior markings seen in some, | 
and the thick ridge on the inside in nearly all, \ 
logs appears to have been — 
TA cut from the borders 
| of the mouth of Strom- 
I bus gigas. Several of 
(| these were found, but all more 
eg or less broken. When whole 
the length was about 150 m. m., — 
breadth from 50 to 60, and the — 
thickness 25 to 30 m. m. The 
broad end is ground to a blunt 
edge like that seen in most of : 
j the stone chisels from the other : 
States, and the other as ground to a blunt point. The 1e 
strument closely resembles the shell-adze used by the Kings- 
mill islanders; specimens of which, with their handles at- 
tached, can be seen in the Smithsonian collections. One of 
the specimens has been twice perforated by a Lithodomus, 
and thus so far weakened as to lead to fracture. These pe- 
forations were undoubtedly made before the instrument Was 
wrought. Its outer surface is largely bored by worms: i 
A large specimen of Pyrula perversa, from which te 
— interior whorls had Deen broken out, was found at T 
Spring. Such as this were used as drinking horns, 2 —
