The ahsts and the heavier cobbles used alternatively as ahsts and hupfs are too fortuitous for reduction to type; while the protean pebbles utilized in emergency, and commonly discarded after a single use, are too numerous and too various for convenient or useful grouping. * * * * * There is a distinctive type of Seri stone artifacts represented by a single category of objects, viz., chipped arrowpoints. Several of the literary descriptions of the folk—particularly those based on second-hand information, and far-traveled rumor—credit the Seri with habitual use of stone-tipped arrows,[297] and it is the current fashion among both Mexican and Indian residents of Sonora to ascribe to the Seri any shapely arrowpoint picked up from plain or valley; yet the observations among the tribesmen and in their haunts disclose but slight basis for classing the Seri with the aboriginal arrow-makers of America. [297] The most specific reference is that of Hardy: “The men use bows and stone-pointed arrows; but whether they are poisoned, I do not know.” Travels, p. 290.
