ed at over
10,000, and the number of inclosures at more than 1500. The great number
of these ancient remains in the regions occupied by the Mound-Builders
is really surprising. They are more numerous in the regions on the lower
Mississippi and the Gulf of Mexico than any where else; and here, in
some cases, sun-dried brick was used in the embankments.

One peculiarity at the South is, that while the inclosures are generally
smaller and comparatively less numerous, there is a greater proportion
of low mounds, and these are often larger in extent. Harrison Mound, in
South Carolina, is 480 feet in circumference and 15 feet high. Another
is described as 500 feet in circumference at the base, 225 at the
summit, and 34 feet high. In a small mound near this, which was opened,
there was found "an urn holding 46 quarts," and also a considerable
deposit of beads and shell ornaments very much decomposed. Broad
terraces of various heights, mounds with several stages, elevated
passages, and long avenues, and aguadas or artificial ponds, are common
at the South. Figure 8 shows the remains of a graded way of this ancient
people near Piketon, Ohio.

At Seltzertown, Mississippi, there is a mound 600 feet long, 400 wide,
and 40 feet high. The area of its level summit measures 4 acres. There
was a ditch around it, and near it are smaller mounds. Mr. J. R.
Bartlett says, on the authority of Dr. M. W. Dickeson, "The north side
of this mound is supported by a wall of sun-dried brick two feet thick,
filled with grass, rushes, and leaves." Dr. Dickeson mentions angular
tumuli, with corners "still quite perfect," and "formed of large bricks
bearing the impression of human hands." In Louisiana, near the Trinity,
there is a great inclosure partially faced with sun-dried bricks of
large size; and in this neighborhood ditches and artificial ponds have
been examined. In the Southern States these works appear to assume a
closer resemblance to the mound work of Central America.

The result of intelligent exploration and study of these antiquities is
stated as follows: "Although possessing throughout certain general
points of resemblance going to establish a kindred origin, these works
nevertheless resolve themselves into three grand geographical divisions,
which present in many respects striking contrasts, yet so gradually
merge into each other that it is impossible to determine where one
