E. Grooveless. A good specimen ([figure 116]) is of quartz and mica, elliptical in section, pointed at ends with one end perforated, from Yellowstone park; another, from Randolph county, Illinois, of hematite, rough, perhaps unfinished.
F. Double cone, with one end ground off flat and hollowed out. The type ([figure 117]) is of granite, one of three from Savannah, Georgia.
G. Top flattened and hollowed out; sides incurving to the middle; lower half a hemisphere. The class is represented by [figure 118] (quartzite, from Randolph county, Illinois), and [figure 119] (sandstone, from Adams county, Ohio). From Kanawha valley there is one of hematite, similar in form to the last.
Fig. 118.—Plummet.
H. Ovoid, with the smaller end ground off flat.[86] A good specimen of this class ([figure 120]) is of magnetite, from Caldwell county, North Carolina. From Savannah, Georgia, there are two of sandstone, both smaller than the type and rough; from Kanawha valley there is one of quartzite, nearly half ground away, leaving almost a hemisphere; and from eastern Tennessee there are one of magnetite and one of quartzite, the latter nearly round.
I. Cylindrical. A unique specimen, from a mound in Loudon county, Tennessee, is illustrated in [figure 121]. It is of sandstone; a short cylinder with incurved sides, each end terminating in a blunt cone.
