The Seri designation for the larger stone implement is that applied to rock generally, viz., _ahst_ (the vowel broad, as in “father”); and it seems probable that the term is onomatopoetic, or mimetic of the sound produced in the use of the implement as a metate, and that its application to rocks generally is secondary. The designation applied to the smaller implement is _hupf_ or _kupf_ (the initial sound explosive, combining the phonetic values of _h_ and _k_; the vowel nearly as in “put”, or like “oo” in “took”); the term is clearly an onomatope, imitating the sound of the blow delivered on flesh, on a mass of partially crushed mesquite beans, etc.—indeed, both the word and the sound of the blow seem to connote food or eating, while regular pounding with the implement (either in ordinary use or by special design) is a gathering signal. So far as ascertained, the term is not extended to other objects save potential implements in the form of suitable pebbles; but it is significant that there is no distinction in speech—nor in thought, so far as could be ascertained—between the natural pebble and the wear-shaped implement.[294] The local terms ahst and hupf are explicit and specific, and without precise equivalents in other known tongues; moreover, the objects designated are too inchoate in development and hence too protean in function to be appropriately denoted by the designations of implements pertaining to more differentiated culture (mortar, metate, pestle, muller, mano, etc.). Accordingly it seems desirable to retain the Seri designations.[295] [294] The failure to discriminate natural objects from artificialized implements produced from such objects by wear of use is a noteworthy trait of primitive folk. It is conspicuous among the acorn Indians of California, who fail to apperceive the manufacture of their own mills and who conceive that their bowlder mortars and creek-pebble pestles, even when completely artificialized by a generation’s use, are merely found and appropriated; and a similar state of mind persists among the well-advanced Papago, who have no conception of making their well-finished mortars and pestles, or even the stone tomahawks occasionally surviving, but regard the implements as fruits of discovery or treasures-trove only. [295] It should be noted that the terms used in the titles of the accompanying plates are not denotive, but merely descriptive.
