It has been to me a fascinating occupation to follow in the foot-steps of my mentor, the veteran prehistorian, Worthington G. Smith, in the study of flint implements in parts of the Lea valley in mid-Herts. At times, I have had the honour of supplementing, in a small way, his well known labours.

One day, in 1903, I had a little while to wait for the train at Hertingfordbury, near Hertford, just above the junction of the rivers Mimram and Lea. Mr. Smith had found implements at Hertford; but none had, as yet, been discovered at Hertingfordbury. A large gravel pit, on the west side of the road, looked tempting. A very hasty search in the failing light revealed a flint (Fig. 62B) of promising appearance in the tough, upper, ochreous gravel, at 10ft. depth from the surface. By strenuous exertions: with hands, to extract it; and with feet, to keep my balance on a tiny ledge, I managed to secure the stone: and catch the train ! This was in the early days of my flint-hunting. But I have never found another quite like it. It has the appearance of an adze, of kite-shaped outline, with an obtusely pointed basal end, for mounting. Very few implements from the river drift, show, to my thinking, any signs of having been made for mounting.
