3. Bark. Specimens of birch bark were found near by the bones. It was no doubt originally used for swathing or wrapping the corpses buried. That a soft decayable substance such as bark, should have lasted while a number of bones had decayed may seem strange. No doubt this may be explained in the same way as the presence among the remains in Hochelaga, on the Island of Montreal, of preserved fragments of maize, viz., by its having been scorched. The pieces of bark seem to have been hardened by scorching.
4. Earth. The main earth of the mound is plainly the same as that of the soil surrounding it. By what means the earth was piled up, is a question for speculation. It seems a matter of small moment. Possibly that the earth was carried in baskets, or vessels of considerable size is sufficient to account for it. My theory is that the mound was not erected by a vast company of busy workers as were the pyramids, but that it was begun at first for purposes of observation, that as interments were from time to time made in it sufficient earth was carried up to effect the purpose, until in centuries the enormous aggregate of earth was formed. Among the earth of the mound are also found in spots, quantities of red and yellow ochre. The fact that the skulls and bones seem often to have a reddish tinge, goes to show that the ochre was used for the purpose of ornamentation. Sometimes a skull is drawn out of the firm cast made by it in the earth, and the cast is seen to be reddened by the ochre which was probably smeared over the face of the slain warrior. The ochre is entirely foreign to the earth of which the mound is made, but being earthy remains long after even pottery has gone to decay.
5. Ore. Lying near this skull as if they had been placed in the hands of the corpse were two pieces of metallic ore, one of which is before you. A fresh section of it shows it to be Arsenical Iron Pyrites, each piece weighing four or five ounces. No doubt the shining ore and its heavy weight attracted notice, although it is of no commercial value. The probabilities are that this ore was regarded as sacred, and possibly having been considered valuable was placed beside the corpse as the ancient obolus was laid beside the departed Greek to pay his fare to crusty Charon.

MANUFACTURED ARTICLES.
1. Stone Implements. The stone articles found, no doubt form a very small proportion of the implements used by the lost race. I am able to show you three classes of implements.
(a.) Scrapers. (See c. Figure 1.) These were made after the same manner and from the same material as the flint arrow heads, found so commonly all over this continent. They are usually of an oval or elongated diamond shape, of various thicknesses, but thin at the edges. Their purpose seems to have been to assist in skinning the game, the larger for larger game, the smaller for rabbits and the smaller fur bearing animals. Probably these implements were also used for scraping the hides or skins manufactured into useful articles.
(b.) Stone Axes and Malls. In the mound on Red River was found the beautiful axe of crystalline limestone, which approaches marble. From the absence of stone so far as we know of this kind in this neighborhood, it is safe to conclude that it came from a distant locality. There are also gray stone celts and hammers used for crushing corn, for hammering wood and bark for the canoes, and other such like purposes, in time of peace; and serving as formidable weapons in time of war. In the mound on the Red River a skull was discovered having a deep depression in the broken wall, as if crushed in by one of these implements.
