ANCIENT MONUMENTS OF THE MISSISSIPPI VALLEY.
ANCIENT WORKS AT BOLIVAR COUNTY, MISSISSIPPI
The works here represented are situated in Bolivar county, Mississippi, near Williams’s bayou in the Choctaw bend, one mile and a half from the Mississippi river. They consist of two truncated pyramidal structures of the character already described, accompanied by two small conical mounds, the whole surrounded by a circular embankment of earth, without a ditch, two thousand three hundred feet in circumference, and four feet high. A gateway opens into the enclosure from the east. Mound A is one hundred and fifty feet square at the base, seventy-five feet square on top, and twenty feet high, with a graded ascent from the east. B is one hundred and thirty-five feet square at base, fifty feet at top, and fifteen feet high. The ascent in this instance is from the north. The two small conical mounds are about thirty feet in diameter, and five feet high. The sides of the pyramidal structures do not vary two degrees from the cardinal points of the compass; a feature not observed in any of the others above noticed. They all, however, appear to have been placed with some reference to these points,—probably as near as they could be located without instruments.
