ARTICLES IN CLAY
Simple vessels in clay may be presumed to cover all forms except eccentric or conventionalized (i.e., animal-shaped) forms on the one hand, and discs and pipes on the other.
Fig. 24. (S. about 1–3.) A chipped hoe or digging-tool, and four specimens from the ancient quarries near Herndon, Tennessee. Phillips Academy collection. A complete nodule is shown in the lower right-hand corner. The others are broken nodules, showing the concretionary character of the flint.
It is suggested by the Committee that members of the American Anthropological Association having occasion to describe clay vessels, may classify them: first, as to material, as consisting of clay, sand, shell, and their combinations, and as possessing certain general ground-color; second, as to manufacture, as sun-dried or fired, as coiled or modeled—with the variations and steps of each process; third, as to form; fourth, as to decoration, as plain, stamped, incised, or painted. With regard to form, the Committee begs to offer the following definitions and suggestions in classifications.
(Note. In all cases measurements are considered as referring to an upward direction.)
A simple vessel must consist of a body, and may have a rim, neck, foot, handle, or any combination.
