To quickly assess the difficulty of the text, read a short excerpt:
In after times the edges were rubbed down on another stone, as hard as or harder than the implement to be constructed; and at a later period still, a rough polishing process was introduced. CAVERNS AND GRAVEL. 217 These latter steps were, however, in all proba- bility, modern innovations, and involved efforts far beyond the powers of the older tribes. Not only are the implements and weapons found in various stages of completeness, but very rough beginnings are sometimes seen, and whole baskets-...full of chips have been described as occurring in some localities. All of these tell the same tale, and although no doubt each one possesses a special interest, little is gained to science by the repetition of specimens, either alike in structure and use, or intended for purposes we cannot at all make out. The main fact is this, that flint and other hard stones bear- ing marks of having been broken artificially into a definite form, afford proof of the existence of human beings at the time when the stones were thus wrought into shape.
