The Ojibwes manufactured chisels out of beavers' teeth.

The Eskimo and some of the neighbouring Amerindian tribes used oblong "kettles" of stone--simply great blocks of stone chipped, rubbed, and hollowed out into receptacles, with handles at both ends.

(It is suggested that they borrowed the idea of these stone vessels for cooking from the early Norse settlers of Greenland; see p.

18.) The Amerindians of the regions west of the Rocky Mountains made kettles or cooking vessels out of blocks of "cedar" (_Juniper_) wood; east of the Rocky Mountains the birch-bark kettle was universal.

Of course these vessels of wood or bark could not be placed on the fire or embers to heat or boil the contents, as was possible with the "kettles" of stone or the cooking pots of clay.
