 EARLY MAN who were capable of making and did make the finest and most regularly- shaped tools. In the brick-earth deposits scrapers are fairly common. A fine, elaborately worked example is shown in fig. 23 ; one with less work is illustrated in fig. 24. A few finely-worked, small implements and lance-like Fig. 23. Fig. 24. forms, some only 2 inches in length, have been found. Various forms of implements of erratic shape and some of uncertain use occur. One of these is illustrated in fig. 25. Flints of this class were possibly throw-stones or missiles ; the one illustrated weighs 6^ oz. Several other specimens and some more symmetrical have been found. A core from Caddington is shown in fig. 26 for comparison. At Caddington the surfaces upon which the palaeolithic folk lived are at times clearly visible on the sides of excavations, sometimes merely as a line of somewhat different colour from the mass of brick-earth. On a line of this sort have been found several implements without flakes or any other stones. At other times there have been many flakes, with implements finished and unfinished, broken examples, failures, cores, flakes and blocks of selected flints approximating in shape, and suitable for implements, all in the position in which they were left by the implement makers. It was possible to see, by careful observation of the surrounding litter of flakes, the places which the tool makers actually occupied while manufacturing implements. Certain of the flakes had been trodden upon and broken, but 1 153 20
