USE BY ESKIMO the Eskimo -had never reached the moun- tains, but, like the southern natives, had procured all the mineral that they required from float and bowlders in the river-beds, as those who have ascended these rivers speak of the abundance of greenstone in sight. We know very little as to the method of working jade by these northern people. Murdochi states that jade was sawed with thin bone saws, sand and water. Nelson® ‘}observed that nephrite and other hard stones were fashioned by the Eskimo by grinding into shape with other stones. Stefansson’ says: Among Noatagmiut (and most other tribes?) greenstone kuinirk bowls were drilled with flint. . . . . Attoktuak (of Point Barrow) says jade was cut into long strips with a sharp cottonwood stick the edge of which was occa- sionally dipped in water and then in dry sand. Noatak people say they never saw or heard of this method. Thin slabs of flint were used, the edge dipped now and then in water and then in dry sand. Slabs of jade were smoothed by rubbing on a flat stone (sandstone) covered with sand. This smoothing practised inland and at Barrow, many of all tribes still living who saw jade worked. AND MONOGRAPHS
