A second and quite common form of copper bead is made of a thin sheet of metal rolled into the form of a cylinder. They vary in diameter from one eighth to one quarter of an inch or more, sometimes exceed two inches in length. They are of quite common occurrence on the Lake Michigan shore and on some inland village-sites. From aboriginal village-sites at Two Rivers and on the shores of Green Bay small cylinders formed by twisting thin sheets of native copper between the fingers in a spiral shape are found. _Bangles._ (_See Fig. 569._) These are also made of thin sheets of native copper. They are of small size, conical or somewhat conical in shape, and open at both extremities. It is believed that these served as bangles, probably taking the place, in the past, of the small metal discs, brass or tin cones, brass thimbles or bells with which it was the custom, among the later Indians, to ornament dress fringes or other articles of wearing apparel. They occur on aboriginal village-sites in the Fox River Valley and in the Lake Michigan shore region. _Finger-Rings_ These consist of small, narrow rods or strips of metal bent into the form of a simple circlet, the ends abutting or nearly meeting. Occasionally the rods are thickest at the middle and taper to a point at the extremities. Some may have served equally well as ear-rings. Specimens are occasionally found in the Lake Michigan shore region, as well as elsewhere in the state. [Illustration: FIG. 620. (S. 1–2.) Copper fish. Hopewell Group.

In the S. D. Mitchell collection is a small crescent-shaped copper ornament which may have served as an ear-ring or nose-ring, being well adapted for such use. It measures one and three eighths inches in extreme width, and was obtained from an Indian village-site in Green Lake County. Similar specimens are in several other local collections. The Reverend W. M. Beauchamp states that the earliest metallic ear-rings in use among New York aborigines were probably those of copper wire coiled and flattened, and believes it possible that perforated discs and coins may have served the same purpose in early historic times, but that they were more likely to have been employed in some other way. Glass and shell beads, and probably many other things, were so utilized. [Illustration: FIG. 621. (S. 1–4.) Copper eagle. Hopewell Group.
