The flints and potsherds, Canon Green well remarks, “occur at times in very large quantities, the flints generally in the shape of mere chippings and waste pieces, but often as manufactured articles, such as arrow points, knives, saws, drills and scrapers, etc.” He further notes that they are found distributed throughout the sepulchral mound, “in some instances in such quantities as to suggest the idea that the persons who were engaged in throwing up the barrow, scattered them from time to time during the process.” Assuredly whatever motive actuated those who contributed such objects while the sepulchral mound was in progress of erection, they were not designed as any slight to the manes of the dead. In districts remote from those where the flint abounds, flakes and chips of the prized material must have been in constant demand to replenish the sheaf of arrows, and replace the lost or broken lance, knife, and scraper. The trader would barter the raw material for furs and other equivalents, or the industrious miner would carry off an adequate supply for his own future use. Such small objects, possessing a universally appreciable value, would be as available for current change as the African cowrie, the Ioqua shells of the Pacific coast, or the wampum-beads of the tribes to the east of the Rocky Mountains. If this assumption be correct, the scattering of flint flakes, while the mound was being piled over the grave, was a form of largess not less significant than any later tribute of reverence to the dead.
