IMPLEMENTS.--The people of Ohio have appropriated the implements of the Mound-builders to a large extent. Almost every homestead in Ohio is ornamented with some of those ancient implements and relics, yet tons have been taken away to grace private and public museums in all parts of this country, and even the museums of Europe and Asia. Among the implements are to be found spear heads, arrow heads; rimmers, knives, axes, hatchets, hammers, chisels, pestles, mortars, pottery, pipes, sculpture, gorgets, tubes, and articles of bone and clothing. Fragments of coarse, but uniformly spun and woven cloth have been found, of course not in preservation, but charred and in folds. One piece, near Middletown, Ohio, was found connected with tassels or ornaments, and may be seen at the Smithsonian Institute at Washington. In Anderson township, Ohio, native gold has been found for the first time. Several small ornaments of copper have been found covered with thin sheets of gold. Earrings also, made of meteoric iron, have been found, and a serpent cut out of mica. Some terra-cotta figures also, which give us an idea of the way the hair was dressed in the days of the Mound-builders. I cannot here name all the implements and ornaments that have been discovered. Though most of them are of hard stone, yet many have been found made of copper. MINING, ETC.--That these people were miners, is evident from the prevalence of various mineral fragments and implements. At Mound City, near Chillicothe, has been found galena, none of which can be found in Ohio. Obsidian also is found in the shape of instruments, which they must have transported from the Rocky Mountains. Ancient mining shafts are found in Minnesota, where the solid rock had been excavated to the depth of 60 feet. On Isle Royal there are pits 60 feet deep, worked through nine feet of solid rock, at the bottom of which is a rich vein of copper, and in the two miles of excavations in the same straight line have been found the mining implements in great numbers. Such advancement in mining, sagacity in warfare, industrial pursuits, and geometric skill, as their works display, prove their great superiority of race over the modern Indian. Their implements, some of them most elaborately made, their brick-making and various other ingenious works, enable us to place them high as an industrial people, while their sacred enclosures, and altars, and tablets, together with the numerous evidences of their being an agricultural nation, enable us to place them far above the modern Indian in the scale of civilization.
