The flint tools, knives, scrapers and the like indicate that they thought they would hunt and slay their quarry when brought down, and fight their foes; and the schist objects found in the graves, which M. de Morgan identifies as amulets, shows that even in those early days man believed that he could protect himself against the powers of supernatural and invisible enemies by talismans.

There was Anvil Mountain, for instance, a bold schist peak crowned with a huge rock in the likeness of a blacksmith's anvil.

Low hills of schist trap and granite formed a country near the river, and farther back high ranges bounded the valley; they appeared to be flat-topped and with horizontal strata of sandstone on the summits.
