“Radisson found that the early Bœuf Sioux of the upper Mississippi Valley tipped their arrows with antler points. A few antler arrow-points have been found in Wisconsin. These are similar to those recovered in Ohio during the recent explorations of Dr. W. C. Mills. In the H. P. Hamilton collection is a portion of an antler which is ornamented with incised designs. It was found in the city of Manitowoc. In the same collection is a small human effigy carved from a piece of antler. Other antler objects found in Wisconsin include awls, a pendant, a tube, and several articles the exact function of which is still undetermined. Cut sections of antler are occasionally found on local village-sites. In the collection of Mr. J. P. Schumacher, at Green Bay, is a pipe made of the tip of a buffalo-horn. On its surface are several incised figures. Pieces of the tusk of a mammoth were obtained with other articles in a Grant County mound. Doubtless a much larger number of both bone and antler implements will yet be found in Wisconsin. Local archæologists have but recently turned their attention to these.” CHAPTER XXX OBJECTS OF COPPER Mr. Charles E. Brown, Dean of the Museum of the Wisconsin Historical Society, Madison, has prepared for me this chapter on copper objects. Mr. Brown’s long association with the Milwaukee Public Museum, and his knowledge of copper collections throughout the United States, have made him an authority on this subject. I have added a few concluding paragraphs to Mr. Brown’s able paper. _The Native Copper Implements of Wisconsin_ The number of native copper articles already recovered from Wisconsin fields, village-sites, mounds, and graves is very large, possibly exceeding that already obtained from the balance of the United States. A careful estimate places the total number of such articles collected in the state up to the present time at not less than twenty thousand. Although the collecting of these implements in Wisconsin has already continued for nearly forty years the supply has not yet become exhausted. The opening to cultivation of new lands in the central and northern portions of the state, the increase in the number of collectors, and the more careful examination of old sites, cause each passing year to add its large number to the total already in collections.
