PLATE III

a. Core of a bowlder of deep-green jade, mottled and
veined, found twelve feet underground in washing for placer
gold on Fraser river, near Yale, British Columbia. It ex-
hibits five polished faces, eight grooves, and four rough ridges
from which sections have been separated for the manufacture
of implements.

6. Water-worn bowlder of deep-green, mottled jade, found
in an old burying-ground at the mouth of Thompson river,
British Columbia. On one face it shows three broader and
two narrower grooves, and two broken ridges from which
sections have been taken. One of these ridges would seem
to indicate that the section was broken transversely in the
process of separation.
