In the Peabody Museum a collection of human bones taken from the shell-banks by Dr. Wyman are arranged to illustrate this sad discovery. It is possible that this people had some relationship to the Caribs. Prof. Forshey has described in brief the vast extent and proportions of the marine shell-banks of the Gulf coast, and the shores of the bayous, lakes and lagoons where Guathodon shells are found. Those of Louisiana, especially near New Orleans, are remarkable, but have yielded no remains, except broken pottery, flint flakes and stone hatchets. A shell-bank at Grand Lake, on the Teche, however, upon which great live-oaks are growing, situated fifteen miles inland, from which the sea has receded since its formation, “yielded unique specimens of axes of hæmatitic iron-ore and glazed pottery.”[99] Probably the most remote shell-bank from the sea containing marine shells, occurs on the Alabama River, fifty miles inland.[100] Fresh-water shell-banks, other than those examined in Florida, furnish evidences of slow accumulation and indicate a comparatively remote antiquity for their origin. On Stalling’s Island, in the Savannah River, two hundred miles above its mouth, is a shell-bank three hundred feet in length by one hundred and twenty feet in width, with an average depth of over fifteen feet.[101] In the American Bottom and on many of the tributaries of the Mississippi, shell-banks occur, composed of varieties of the Unios and Anodons. A remarkable example of such accumulation is the well-known shell-bank a mile and a half south of New Harmony, Indiana, and situated on a high hill 170 feet above the level of an arm of the Wabash River. The bank covers an area of a quarter of an acre, and has attracted the attention of eminent scientists like Leasure, Say, Lyell and others, but nothing of value was developed that would refer the construction of this and similar banks to any people more ancient than the Mound-builders.[102] On the Pacific coast, great numbers of shell-banks exist, but contain nothing different from those in other parts of the country. (See Researches in the Kjökken Möddings of the Coast of Oregon and of the Santa Barbara Islands and Adjacent Mainland, by Paul Schumacher. _Bulletin of U. S. Geol. and Geog. Survey_, vol. iii, No. 1.) There can be little doubt but these strange and vast accumulations indicating the presence of an extinct population, had a remote beginning, and have been added to from time to time by different peoples, removed from each other both by the diversities of race and the lapse of time.
