EXPLANATION OF PLATE LXXV.

TWISTING LEVERS FOR SINEW-BACKED BOWS OF ESKIMO.

This plate shows the manner in which the ivory levers are used in winding up the double cable on the back of an Eskimo bow. It will be seen that each lever has a hook at each end, but on alternate sides. The end of each lever is thrust through the middle of a loose cable, hook side downward. It is then revolved through half a circle, as far as it will go, then pushed its entire length, which brings the hook at the other end in place for another half turn, and so on. A rawhide string is passed through both cables, wrapped about the grip and made fast. This prevents the cables from unwinding while the bow is in use.
