_Hopewell Mound, Chillicothe, Ross County, Ohio._--A later discovery of the Swastika belonging to the same period and the same general locality--that is, to the Ohio Valley--was that of Prof. Warren K. Moorehead, in the fall and winter of 1891-92, in his excavations of the Hopewell mound, seven miles northwest of Chillicothe, Ross County, Ohio.[254] The locality of this mound is well shown in Squier and Davis's work on the "Monuments of the Mississippi Valley" (pl. 10, p. 26), under the name of "Clark's Works," here reproduced as pl. 11. It is the large irregular unnumbered triple mound just within the arc of the circle shown in the center of the plan. The excavation contemplated the destruction of the mound by cutting it down to the surrounding level and scattering the earth of which it was made over the surface; and this was done. Preparatory to this, a survey and ground plan was made (pl. 12). I assisted at this survey and can vouch for the general correctness. The mound was surrounded by parallel lines laid out at right angles and marked by stakes 50 feet apart. The mound was found to be 530 feet long and 250 feet wide. Squier and Davis reported its height at 32 feet, but the excavation of the trenches required but 18 and 16 feet to the original surface on which the mound was built. It was too large to be cut down as a whole, and for convenience it was decided by Mr. Moorehead to cut it down in trenches, commencing on the northeast. Nothing was found until, in opening trench 3, about five feet above the base of the mound, they struck a mass of thin worked copper objects, laid flat one atop the other, in a rectangular space, say three by four feet square. These objects are unique in American prehistoric archæology. Some of them bore a resemblance in form to the scalloped mica pieces found by Squier and Davis, and described by them in their "Ancient Monuments of the Mississippi Valley" (p. 240), and also those of the same material found by Professor Putnam in the Turner group of mounds in the valley of the Little Miami. They had been apparently laid between two layers of bark, whether for preservation or mere convenience of deposit, can only be guessed. [Illustration: PLATE 11. PLAN OF NORTH FORK (HOPEWELL) WORKS.
