148 EXPLORATION OF BURTON MOUND [ETH. ANN, 44 
SHELLS FOR STRINGING 
Several species of shell were found perforated for stringing entire. 
Conspicuous among these is the small species of olivella with spire 
ground off by rubbing on a rock so that a string can be inserted. 
(Pl. 26,7.) A few specimens of the large olivella were found pre- 
pared in the same way. Cowrie shells were found with the back 
broken through, apparently for stringing. 
The dentalum is a natural tube and does not have to be per- 
forated for stringing. It was rare on the Channel, occurring only 
in the deeper waters, but was known to the Indians and a number 
of specimens were taken. Sections of dentalium were used as bush- 
ings for the ends of cylindrical and other types of beads. 
Two specimens of clamshell were found which had been bored 
near the hinge, apparently for the purpose of stringing. The holes 
are about 3 mm. diameter. The maximum diameter of the shells is 
about 43 mm. 
RiM PONDANTS OF ABALONE 
These are cut from the inner lip of the abalone shell, from the red 
abalone in the specimens obtained. An ornamentation of zigzag or 
transverse incisions is found on some rim pendants. 
Butt fragment of abalone rim pendant, 44 mm. long, 8 mm. wide, 4 mm. thick. 
Hole 2 mm. diameter, 2 mm. from butt end. The outside edge is ornamented 
with transverse incisions cut about 1 mm. apart. 
Butt fragment of abalone rim pendant, 36 mm. long, 6 mm. wide, 1.5 mm. 
thick, Hole 1.5 mm. diameter bored 8 mm. from the butt end. 
Butt fragment of abalone rim pendant, 47 mm. long, 9 mm. wide, 2 mm. thick. 
Hole 1.5 mm. diameter bored 2 mm. from the butt end. 
Butt fragment of abalone rim pendant, 52 mm. long, 14.5 mm. wide, 5 mm. 
thick. Hole 2 mm. diameter 3 mm. from butt end. 
Entire abalone rim pendant, 125 mm. long, 7.5 mm. wide, 2.75 mm. thick. 
Hole 2 mm. diameter, 2.5 mm. from the butt end. From the butt extending to 
13 mm. from the tip, the outer edge is ornamented with zigzag incisions. 
(Pl. 25, @:) 
Central fragment of abalone rim pendant, 51 mm. long, 7 mm. wide, 3 mm. 
thick. The fragment contains no perforation. The outer edge has remains of 
transverse incisions, 1.25 apart; these incisions have been partly worn off. 
Entire abalone rim pendant, 41 mm. long, 6 mm. wide, 3.75 mm. thick. Hole 
1.5 mm. diameter, 3 mm. from the butt. 
Central fragment of abalone rim pendant, 52.5 mm. long, 7.5 mm. wide, 3 min. 
thick. 
Central fragment of abalone rim pendant, 47.5 mm. long, 9.5 mm. wide, 2 mm. 
thick. In quite decayed condition. 
Fragment of abalone rim pendant, 27.5 mm. long, 6.5 mm. wide, 2 mm. thick. 
The entire outer edge is incised with transverse scorings. 
Butt fragment of abalone rim pendant, 76 mm. long, 6 mm. wide, 3.5 mm. 
thick. The hole is 2 mm. diameter and the end of the specimen beyond the 
hole has been broken away. Traces of transverse incisions are still visible 
along the lower portion of the outer edge.
