 houses; since, as the highest, and because they are straight, they were best adapted to the purpose. The situations of these pueblos at short distances from each other on the same stream accords with the usages of the Village Indians of New and Old Mexico and Central America in locating their villages These pueblos were probably occupied by Mound-Builders of the same tribe, and were not unlikely under a common government, consisting of a council of chiefs. It is probable, also, that they were constructed, one after the other, by colonists from an original village.

In the engraving, Fig. 40, the form and relations of the embankments are shown, with cross-sections indicating their elevation and present grounddimensions. It was taken from the work of Squier and Davis. These authors remark that "the principal work consists of an octagon and circle, the former measuring nine hundred and fifty feet, the latter ten hundred and fifty feet in diameter. * * * The Nvalls of the octagon are very bold, and, where they have been least subject to cultivation, are now between eleven and twelve feet in height by about fifty feet base. The wall of the circle is much less, nowhere measuring over four or five feet in altitude. In all these respects, as in the absence of a ditch and the presence of the two small circles, this work resembles the Hopeton Works." Of the latter, which is nine miles above on the Scioto, they remark that "the walls of the rectangular work are composed of a clayey loam twelve feet high by fifty feet base * * * They resemble the heavy grading of a railway, and are broad enough on the top to admit of the passage of a coach."

It will be noticed that the octagonal work shown in the engraving consists of seven distinct embankments. Six of these are about four hundred and fifty feet long, and the remaining one, which once consisted of two equal sections, as shown by the mound to face an original opening in the center, now forms one continuous embankment facing one side of the inclosed area. If these embankments were reformed, with the materials washed down and now spread over a base of fifty feet, with sloping sides and a level summit, they would form new embankments thirty-seven feet wide at base, ten feet high, and with a summit platform twenty-two feet wide. If a surface coating of clay were used, the sides. could be made
