Prof. C. G. Forshey in _Foster’s Pre-Historic Races_, presents most valuable information relative to the mounds in the south-west. His observations convince us that the State of Louisiana and the valleys of the Arkansas and Red Rivers were not only the most thickly populated wing of the Mound-builder domain, but also furnish us with remains presenting affinities with the great works of Mexico so striking that no doubt can longer exist that the same people were the architects of both. He describes works, some of them of immense proportions, on the Mississippi fifty miles above Vicksburg; on Walnut Bayou; the south-west bend of Lake St. Joseph, and at Trinity in the parish of Catahoula, Louisiana. On the east bank of the Little River, a couple of miles above its mouth, where it empties into Lake Ocalohoola, stands a bluff walled with roughly hewn stone. The same writer observed a mound near Natchez twenty-five feet high, standing isolated in a swamp. This mound is one among many in different parts of the lower Mississippi region surmounted by comparatively younger trees than are found on the remains farther north. Works occur in the Atchafalaya basin, in the rear of Baton Rouge, on the uplands of Lake Pontchartrain and on the banks of Bayou Gros Tête. A remarkable group of truncated pyramids, peculiarly Mexican in their style of architecture, exist in Madison Parish, Louisiana, and are figured in Squier and Davis and copied by Foster.[62] It is needless to discuss the fact that the works of the Mound-builders exist in considerable numbers in Texas, extending across the Rio Grande into Mexico, establishing an unmistakable relationship as well as actual union between the truncated pyramids of the Mississippi Valley and the Tocalli of Mexico and the countries further south.[63] There can be no doubt as to the unity of the origin of the works in both countries. There are evidences also that the most recent works of Louisiana and Texas do not compare in antiquity with any found in the Ohio Valley, showing it to be altogether probable that the Mound-builders occupied the Lower Mississippi Valley and Gulf coast for a considerable period after they were driven from the northern and central region by their enemies.[64] Several recent writers, with no more proof than that obsidian from Mexico has been found in the mounds, have confidently expressed the belief that the Mound-builders entered the Mississippi Valley and the Central Region from the South. This was based also on the assumption that no remains were found in the North-west. It, however, is proper to note here the marks of architectural progression observable in the geographical distribution of ancient works. Men all around the world have been mound or pyramid builders. To attempt to demonstrate this well-known fact to an intelligent reader by citing the customs of antiquity and the works of the present great Asiatic nations, would seem little
