460 NOTES ON THE TEN THOUSAND ISLANDS, FLORIDA. 
Occasionally in the shell debris at Marco were “chipped and notched fragments 
of heavy clam-shells,” like those found by Cushing! on nets in the muck at Marco; 
while a fossil-shark’s tooth, beveled and showing signs of use, probably as a knife, 
was picked up by us in the shell debris of a cul- 
tivated field. Teeth of sharks, though fossil

sharks are not specified, were found by Cushing,” set in handles for use as carving 
tools. 
We got also at Mareo—and the inhabitants say that many have been gathered 
from the surface near there—a fragment of clam-shell wrought on one side to a 
very sharp cutting edge (Fig. 9). These probably 
were hafted as knives or, perhaps, were the blades 
of small hand-adzes, as described by Cushing, 
though “little blades made either from bits of shell, 
the sharp ventral valves of 
oysters,’ and not clam- 
shells, are mentioned by 
him.

place, northward toward 
Naples—all noteworthy, aboriginal shell deposits. 
A number of interesting objects came from Goodland Point, Key Marco, among 
which is a gorget of shell (Fig. 10) with the aboriginal sign of the four directions. 
A pendant from the same place (Fig. 11), made from fossil bone or from some 
coral material (we have not wished to cut into the specimen to determine it), bears 
an incised design on each of the four sides—two showing the eye; опе, a mouth or 
jaws; and one being indistinguishable. Three of these designs are shown in 
diagram in Fig. 12.
