NELSON] DRILL-CAPS 83 
Figure 30, from St Lawrence island, is a piece of walrus tusk, about 
five inches in length, roughly oblong in shape, with a conical depression 
in one side for receiving the top of the shaft. 
Figure 29, from the same locality, is another rough piece of walrus 
tusk, made with a conical depression in each side for receiving the top 
of the shaft. These two are the rudest implements of this description 
that were obtained. 
Figure 27 is a cap having the wood rudely carved into the form of a 
seal, with a square hole through the tail, in which the drill cord can be 
tied when not in use. This specimen is from the Kuskokwim. 
Figure 22, from Norton sound, is a cap with an oval piece of white 
quartz set in the lower side and the wooden portion carved in the form 
of a wolf fish. 
Figure 28, from Cape Nome, has a square piece of grayish-white 
stone set in its lower surface, and the two long arms, one at each end, 
are carved to represent the heads of white bears. This drill cap is 
intended to be used either singly, with the crossbar mouthpiece, or by 
grasping the ends with the hands. Figure 27, from the Kuskokwim, 
is a similar cap, having inserted a piece of stone, mottled green, black, 
and white in color. 
Figure 23, from Agiukchugumut, is made in the form of a seal, with 
a hard, milky white, flat stone set in its lower surface. 
Figure 25, obtained on Nunivak island by Dr W. H. Dall, is made 
from an oval piece of white quartz with a conical depression in its lower 
surface. A groove extends around the side, in which is fastened a raw- 
hide cord with a loop at one end to which the drill cord can be fastened. 
Figure 24, from Sabotnisky, is a long, oval, green and black stone, 
having the usual conical pit in one side; this, like the preceding, is 
made for holding in one hand. 
Figure 26, from Cape Nome, is a long, rather slender cap or handle 
of wood, having a small, square piece of stone set in its lower surface 
and provided with a projecting block on its upper side for grasping 
with the teeth; it is carved at each end to represent a wolf’s head, and 
is intended for use with either a large or a small drill. A cap obtained 
at Cape Darby is also made to serve for both kinds of drills. 
The caps to be used exclusively with the small drills, worked with a 
bow, are always provided with a projecting block on the upper sur- 
face for grasping with the teeth, and are much more elaborately made 
than are those used with the larger drills. They are commonly some- 
what crescentic in form, and have a piece of stone or lead set in the con- 
vex lower surface; where stone is used it is cut usually into a square or 
rounded outline and is neatly inlaid. Two specimens, however, are of 
walrus ivory and are without any stone setting, the conical depression 
being made directly in the material of the cap. Of these, figure 16 is 
from Cape Nome and figure 17 from the Diomede islands. 
Figure 11, from the lower Yukon, has a crescentic outline and is 
carved on the convex surface at one end to represent a human face and
