The largest temple mound in the South is near Seltzertown, Mississippi. Its base covers about six acres, and it rises forty feet. This slope was ascended by means of a graded way. The summit platform has an extent of nearly four acres. On this platform three other mounds had been reared—one at each end, and a third in the center. Recent investigation by the Bureau of Ethnology have shown that the base of this mound is a natural formation. Lumps of sun-dried, or partially burnt clay, used as plastering on the houses of the Mound Builders, gave rise to a sensational account of a wall of sun-dried bricks two feet thick, supporting the mound on the northern side.39 The famous Messier Mound, in Georgia, is said to reach a height of ninety-five feet. But a large part of this elevation is a natural eminence; the artificial part is only a little over fifty feet. Etowah Mound, Georgia. A work of unusual interest occurs on the Etowah River, Georgia. This cut gives us a plan of the work. We notice, first of all, the moat or ditch by which they fortified their position. The ditch is still from five to twenty-five feet deep, and from twenty to seventy-five feet wide. It connects directly with the river at one end, but stops short at the other. It surrounds nearly fifty acres of land. At two points we notice reservoirs, each about an acre in size, and an average depth of not less than twenty feet. At its upper end is an artificial pond. This ditch, with its reservoirs and pond, is no slight work. The large mound seen in the center of the space is one of the largest of the temple mounds. Its shape is sufficiently shown in the cut. The height of the mound is sixty-five feet. We call especial attention to the series of terraces leading up the south side of the mound. Graded ways afford means of access from one terrace to the other. A pathway is also seen on the eastern side.
