evidence. In 1892[1] I found another small implement (4 inches) of rude ovate form, among some stones recently placed in a rut at Bedmond Hill. Here, again, there is no evidence as to the exact geological position. Nor is there with regard to two other implements, both of which I found in 1868, in gravel laid on the towing-path of the Grand Junction Canal, which is there united with the Gade, between Apsley and Nash Mills, about two miles south of Hemel Hempstead. There is, however, no doubt of the gravel in which they lay having been dredged or dug from the bottom of the valley in the immediate neighbourhood. One of them, of grey flint, is a neatly-chipped, flat implement, of ovate outline, about 4 inches long, in form much like Fig. 468, from Lake. The other is imperfect, but appears to have been originally of much the same character, though flatter on one face. It is deeply stained of an ochreous colour, and its angles are considerably waterworn. I have searched in the gravels of the neighbourhood for other specimens, but as yet in vain. I may add that during the formation of this part of the canal, some eighty years ago, an elephant's tooth was found in the gravel, within about 200 yards of the spot where I discovered one of the implements.
Other specimens are reported to have been found near the head of the tributary valley of the Bulbourne, at Wigginton, near Tring.
At Watford, Herts, on the left bank of the Colne, in gravel near Bushey Park, at a height of about 40 feet above the level of the existing river, Mr. Clouston has found several implements of ochreous flint of various types. He has kindly given me a square-ended flake, much like Fig. 426a, from High Lodge, Mildenhall.
Some of the discoveries made by Mr. Worthington G. Smith were in localities within the valley of the Ver, an affluent of the Colne, rather than in that of the Lea, but inasmuch as many of the beds which contained the implements found by him seem to bear but little relation to existing watersheds, and are at no great distance from the Lea, I shall at once proceed to the discussion of the remarkable series of facts which he has brought to light. All details must, however, be sought for in Mr. W. G. Smith's own book, "Man, the Primeval Savage."[2]
