These implements range in size from less than two to as much as eight and an eighth inches. The average size appears to be between two and three inches. Such implements are to be seen in many of the eastern Wisconsin collections. In the Milwaukee Public Museum is a small series of copper needles from Mexico. _Fish-Hooks._ (_See Fig. 603._) Hundreds of these and fragments of many others have been collected from the aboriginal village- and camp-sites on the west shore of Lake Michigan in Wisconsin. They have also been obtained in numbers from the village-sites at Green Lake and at various other localities along the upper Wisconsin, Fox, Wolf, and Little Wolf rivers, and elsewhere in this part of the state where good fishing was to be had. Some have also been found far to the north along the Lake Superior shore. Most specimens are of small size, from less than an inch up to two inches in length. The largest known example is four inches in length. They are generally circular, though sometimes decidedly square in section. The points curve and slant outward and inward at all angles and degrees of curvature. None possess any indication of a barb. The shank at the point of attachment to the line is most frequently straight. Sometimes, however, it is notched, flattened, bent over and flattened, or bent over to form an eye. A few specimens have been collected which have bits of sinew or twisted fibre still attached to the shank. Fine series of these useful articles are to be seen in many local collections. In the H. P. Hamilton collection there is a series of ten fish-hooks obtained from the bank of the Little Wolf River, in the township of Muckwa, in Waupaca County. These are from two and a half to two and three fourths inches in length, the strongly and broadly curved hook reaching up to about opposite the middle of the shank. Some are circular and others square in section, and all are of a nearly uniform thickness of one fourth of an inch. Several have the tips of the shank flattened, and all are heavily incrusted with soil and verdigris, plainly indicating the manner in which they had lain upon and across each other. _Peculiar Implements_ In a few of the large Wisconsin cabinets are to be seen a very small number of implements whose exact functions are unknown and which cannot be placed in any of the various classes here described.
