It is interesting to learn of the recovery of this lost art of the ancient arrow-makers by a series of tentative experiments independently pursued by different observers. Before Mr. Cushing’s attention had been directed to any of the descriptions of the process of modern flint-workers, now familiar to us, he aimed at placing himself in the same condition as the primitive manufacturer of Europe’s Stone Age, or of the ancient Mound Builders of North America, devoid of metallic tools, and with the flint, obsidian, jasper, or hornstone, as the most available material out of which to fashion nearly all needful implements. He set to work accordingly with no other appliances than such sticks and variously shaped stones as could be found on the banks of the streams where he sought his materials. The results realise to us, in a highly interesting way, the earliest stages in the training of the self-taught workman of the Palæolithic Age. After making various implements akin to the most rudely fashioned examples from the river-drift or the old flint pits, by means of chipping one flint or stone with another, he satisfied himself that no amount of chipping, however carefully practised, would produce surfaces like the best of those which he was trying to imitate. He accordingly assumed that there must be some other process unknown to him. By chance he tried pressure with the point of a stick, instead of chipping with a stone, and the mystery was solved. He had hit on nearly the same method already described as in use by Aztecs, Eskimos, and Red Indians; and found that he could fashion the fractured flint or obsidian into nearly any shape that he desired. As has been already noted, Mr. Cushing, like Dr. Evans, resorted subsequently to the easily available tool furnished by the handle of a tooth-brush. Having thus mastered the secret of the old flint-workers, he succeeded before long in the manufacture of well-finished arrows, spear-heads, and daggers of flint, closely resembling the products of the primitive workmen both of the Old and the New World.
