1412. (42206). Grooved axe of black fine-grained sandstone, about eight inches long; water-worn to its present shape, afterward grooved to render it suitable for use.
1413. ([42207]). Fig. [504]. Grooved axe, of basalt. The only specimen of this particular form in the collection.
1414. ([42208]). Fig. [505]. Large stone celt of coarse sandstone, light gray color. It is shaped more like a wedge than the cut indicates. It is difficult to conjecture what this implement could have been used for. The sandstone of which it is made is too soft for either splitting or hammering. As it is about ten inches long and has four flat sides it may have been a grinder, as many of those implements are not unlike it in length and appearance. Its surface is quite rough and pitted.
1415. (42209). Sandstone maul, grooved, surface rough.
1416. (42210). Triangular-shaped maul, grooved in the middle; of coarse basalt. This and similar mauls evidently at one time had handles fixed to them, but at the present day it is not uncommon to see the modern Pueblo Indians holding them in the hand to crush their grain, chili or red-pepper pods in round mortars.
1417. (42211). Grooved axe of basalt.
1418. (42212). Small grooved axe of metamorphic rock.
1419. ([42213]). Fig. [507]. Water-worn boulder of quartzite, grooved around the centre.
