Archives of aboriginal knowledgeContaining all the original paper laid before Congress respecting the history, antiquities, language, ethnology, pictography, rites, superstitions, and mythology, of the Indian tribes of the United States . the Balize marksits extreme protrusion into the Gulf of Mexico. Not less than three thousand milesare required for the display and evolutions of this river; and when we revert to itssource, it is found to be on a continental summit of less than eighteen hundred feetelevation above the Atlantic. This summit is formed by an upheaval of the crjstallineand trap rocks which form such striking displays in the basin of Lake Superior, Formation at the Sources of the Mississippi. In order to comprehend the geology of this region, it is necessary to premise, thatthis continental elevation of the granitic series, moderate as it is, bears a heavy massof drift strata, all of which are the material of pre-existing and broken-downformations. These appear to have been chiefly sandstones, slates, schistose rocks,amygdaloids, and traps; the latter of which have existed in vast dykes in the under-lying ranges, conformably to the system exhibited in the basin of Lake Superior.(Vide Geol. Map, herewith.).
