An aberrant form is elliptical in section at the middle, round or nearly so at the ends, the sides expanding rapidly from end to middle by double curves. It is represented by [figure 146] (ferruginous quartz, from Kanawha valley, West Virginia), and by a specimen of quartzite from Union county, Mississippi.
Boat-shape Stones.
There are two types of relics, perhaps ceremonial, for which no use has been determined, and which are named from their general resemblance to the form of a boat. They are as follows:[107]
A. With flat face more or less hollowed, sides triangular and parallel. A number are not perforated. The type is shown in [figure 147] (striped slate, from Davidson county, North Carolina).
