The processes of manufacture employed in this area as indicated by the archaeological objects found include fracturing by chipping and flaking, pecking or bruising, grinding, polishing, cutting by grooving and breaking, incising, whittling and gouging, and drilling. The materials worked by each of these processes may be seen among the specimens here figured and described. Spinden states[213] that in the Nez Perce area chipped implements were made by the men and that the pecked artifacts were made by the women.
