One of the minor mysteries of American archaeology concerns the use made by the Indians of certain stone disks found in the Mississippi Valley and the Southeast. According to Charles C. Jones, Jr., the first of these disks was “ploughed up in 1859, on the lower terrace of the large temple-mound on the Etowah River … near Cartersville,” Georgia. Other discoveries followed, and several scores of the disks are now in archaeological collections.
