The pottery found is quite extensive, some mounds have been opened in which were upwards of sixty vases, some quite plain, and others elaborately ornamented. Of the pottery, Dr. Dickeson has succeeded in getting upwards of a hundred fine specimens to Philadelphia, which are deposited with his other Indian relics and fossils, in the Museum of the Academy of Natural Sciences. Dr. Dickeson has kindly furnished me a catalogue of his collection of relics, from which I have selected the following to give an idea of the extent and variety of the objects found: 6000 Arrow points of jasper, chalcedony, obsidian, quartz, &c., &c. 150 Arrow points, finely polished, under one inch in length. 25 Arrow points, finely polished, under half an inch in length. 1600 Unfinished Arrow and Spear points. 250 small stone Axes. 40 Quoits, Weights, &c. 20 Paint mullers. 10 Corn grinders. 3 large stone Mortars. 14 small earthen Heads of men, women and boys. 6 stone Statues, erect and sitting. A great variety of personal ornaments of jasper, chalcedony, pottery, beads, pearls, war clubs, war axes, mica mirrors, carved ornaments, arm bracelets, bone carvings, earthen plates, handled saucers, earthen lamps, a variety of vessels for culinary purposes, stone chisels, two copper medals, the tusk of a Mastodon, six feet long, elaborately carved with a serpent and human figures; cylindrical tubes of jasper perforated, ornaments in pumice, (lava), seals, bricks, jars, cups and vases in every variety. In addition to these, Dr. Dickeson has made a collection of upwards of sixty crania of the ancient mound builders, out of many thousand skeletons discovered by him in his several explorations. These possess much interest in an Ethnographic point of view, for the rigid test to which all his results have been subjected, have satisfied him that these skulls belong to the ancient race. Like the gentlemen in Ohio, whose labors have been noticed, the Doctor can at once detect the mounds and remains of the ancient, from those of the modern race. Some mounds he has found to be the work of three periods. At the top were the remains of the present race of Indians; digging lower he found these remains accompanied by ancient Spanish relics, of the period of the earliest Spanish visit to these parts; and below these, he discovered the remains and relics of the ancient race.
