THE USE OF METALS
Fig. 24—Implements and Ornaments of Copper.
Although strictly a Stone Age people, the Mound-builders used Copper, Silver and other native metals. They had not learned to melt these, but pounded the metal into the desired shape, afterward polishing the objects by rubbing. The objects shown in the picture are all made of Copper. “A” is a Bracelet and “B” is a Celt, or ungrooved Axe. “C” shows two views of what are called Ear-spools. These were worn as ornaments in the ears, and probably signified some particular station in life. The Mound-builders obtained their copper from the shores of Lake Superior, where it is found near the surface of the ground. Many of the pits they dug there are still to be seen. Silver was also obtained by them in the same region.
Besides Copper and Silver, the Mound-builders used Galena, or Lead-ore, and Iron, which they probably obtained from fallen meteors. The non-Mound-building Indians used copper to a lesser extent.
