140 Primaeval Man in the Valley of the Lea. last year—what a tale the deep glacial scratches tell on the original crust. One implement seems to say that its maker had light and skilful fingers, and a true eye for a beautiful and correct form. One example seems always to say that it was made by an old man who had made many hundreds of such tools before: the perfection of the manufacture and the dexterity of the flaking prove it. Another seems to say that it was made by a raw beginner, and confesses itself by its form to be a failure, an abortion, and a waster, angrily thrown away as worthless. One big acutely-pointed tool seems to say that it was made specially to attack a Mammoth, a Rhino- ceros, a Lion, a Horse, or a Man. Another confesses by its shape to being a domestic tool, made by primaeval hands to scrape the flesh from the bones of a Horse, or to prepare a skin for a rude cloak. One says it was used for splitting wood, another for felling a beast; some say they were made for neat work, others for coarse ; some for hunting, others for peaceful purposes at home. One tells how it lost its acute point in a desperate contest, or by a provoking accident; another how it lost its edge by long hacking at tough green wood; another tells how its butt-end had been battered by constant hammering: all shadow forth something to the thinking observer. Although it is easy to suggest the probable uses to which many of the implements were put, yet there remain some forms which defy all explanation ; our knowledge at present is so imperfect of the men who made the tools and the mode of life of those men that a ready explanation is hardly to be expected of every object found in association with the ordinary well-defined implements. Although there is considerable variety of form in Palaeo- lithic implements, and although several new forms have been detected during the last ten years, it is very remarkable that Palaeolithic men did not vary their tools more than they did. When the pointed tongue shaped weapon was invented, and then the oval or ovate tool with a cutting edge all round or with an unworked butt, the men as a rule were unable to proceed beyond the scraper to other forms;
