Deer and elk horns enter largely into the manufacture of many of the relics. Among others are what are known as bone arrow or spear

points, shown in Figs. 3 and 4. They are invariably made from the sharp points of horn, the piece being first cut off, and then a hole drilled into the blunt end with a flint. Marks made by the drill are still distinctly seen in the holes. The points were fastened to wooden shafts inserted in the holes. Now, strange though it may seem, relics

of an exactly similar make and of exactly the same sort of material are found thousands of miles away. Dr. F. Keller, in his elaborate book on the "Lake-Dwellers of Europe," gives figures[2] of these implements found in the Swiss lake-dwellings, and Fig. 5 is taken from his book. It is immediately seen that the relics from the two localities are identical, with the exception of the small hole drilled into the side. In Fig. 5 one of the arrow-points has a portion of the shaft still fastened in the hole.
Large pieces of deer and elk-horn, with the prongs polished by constant use, have probably been employed as digging implements. Smaller pieces of the flat part of the horn, with two or three prongs,
