Another, and in some respects more interesting discovery, was made at a point lying to the cast of Keweenaw Point, in the rich iron district of Marquette, in what appears to have been the ancient bed of the river Carp. About ten feet above the present level of its channel, various weapons and implements of copper were found. Large trees grew over this deposit also, and the evidences of antiquity seemed not less obvious than in that of Ontonagon. The relics included knives, spear or lance-heads, and arrow-heads, some of which were ornamented with silver. One of the knives, made, with its handle, out of a single piece of copper, measured altogether about seven inches long, of which the blade was nearly two-thirds, and of an oval shape. It was ornamented with pieces of silver attached to it, and was inlaid with a stripe of the same metal from point to haft. Numerous fragments and shavings of copper were also found, some of which were such as, it was assumed, could only have been cut by a fine sharp tool; and the whole sufficed to indicate, even more markedly than those at Ontonagon, that not only was the native copper wrought in ancient times in the Lake Superior regions, but that manufactories were established along its shores, and on the banks of its navigable rivers. The recognition of silver as a distinct metal by the present race of Indians is proved by the specific term _shooneya_, by which it is designated in Chippewa; whereas gold is only known as _ozahwah-shooneya_, or yellow silver.
