tumuli which mark the corners of the mound, retain the impressions of human hands.[52] The Mound-builders were certainly numerous in the Gulf States east of the Mississippi. On the Etowah River in Alabama a mound seventy-five feet high and twelve hundred feet in diameter at the base, has a graded avenue leading to its flattened summit. It has close affinities to the Mexican and Yucatan mounds.[53] M. F. Stephenson describes a group of ten mounds near Cartersville, Georgia, on the Etowah River, the principal one of which is eighty feet high and one hundred and fifty feet square on the top. A stone idol, gold beads, mica mirrors, translucent quartz beautifully wrought, and many relics of interest were here discovered. He also describes three chambers hewn out of the solid rock at the falls of Little River, near the Alabama line; while at Nacooche the crest of a conical hill was cut off at fifty feet from its base, leaving a platform top with an area of an acre and a half. Two sides are quite precipitous, but the others are protected by a ditch and wall. Two other instances of the stone wall are mentioned. First at Yond Mountain, four thousand feet high of solid granite, and perpendicular on all sides except a small space which is protected by a stone wall of artificial construction. The second instance is quite similar, occurring at Stone Mountain, which reaches a height of 2360 feet.[54] These natural eminences no doubt were utilized for the purposes of worship or observation, just as many natural hills in Mexico were graded and shaped symmetrically to serve similar uses. Wm. McKinley, Esq., has described and surveyed additional works in Georgia of quite a remarkable character, on Sapelio Island in McIntosh County and on Dry Creek in Sacred Grove, Early County. But the most lofty work of all, the giant of the mounds, is the pyramid of Kolee Mokee in the same county, reaching a height of ninety-five feet and having a circumference at its base of 1128 feet. Its form is that of a parallelogram, 350 feet long and 214 wide. The plane on the summit measures 181 feet in length by 82½ feet in width.[55] In Florida the works of the Mound-builders have been extensively examined by Prof. Jeffries Wyman, to whose labors we shall refer in the next chapter. Dr. A. Mitchell made some interesting explorations in 1848 on Amelia Island, and was rewarded by the recovery of some well-marked mound crania.[56]
