Note 7 — Chapter I

Squier and Davis: Ancient Monuments of the Mississippi Valley, Washington, 1848, 4to, 1st vol. of Smithsonian Contributions; Dr. J. A. Lapham: Antiquities of Wisconsin, Smithsonian Contributions to Knowledge, 1855. More recently—The Upper Mississippi, by George Gale, Chicago, 1868; The Mississippi Valley, by Dr. J. W. Foster, Chicago, 1869, 8vo, and his Pre-Historic Races of the U. S., Chicago, 1873, 8vo. We might add a list of names scarcely less eminent, of authors who have written upon special fields and examined particular works. A reliable bibliography of literature on the Mound-builders is a desideratum which we trust some enterprising Americanist may soon supply.
