A NEOLITHIC FLOOR. 251 party of its members to inspect his discoveries, and he freely placed all the facts at the Club's disposal. This visit took place on the 15th October last, and it proved to be of such interest that it was thought that a general account of what had been seen would be acceptable to the Essex Field Club. This account, so far as I am concerned, must, however, be regarded merely as preliminary, and with a view to making these discoveries more widely known, so that others having leisure and opportunity may pursue the investigations further. Mr. Rand, with a true scientific instinct, cordially invites assis- tance from anyone who may be interested, and has no desire to keep either the localities secret, or their investigation to himself. HAMBOROUGH HILL. In the first case, I will deal with the site of Ham- borough Hill, which is a ridge capped with gravels and Bagshot Sands, about a mile north of Rayleigh. (Plan Fig. i.) The whole of the top soil on a portion of this site is being dug out and removed by Mr. Rand, for use in his green-houses, and during this process a large number of flint-flakes and implements have been found (See Plate XV.). The implements are of the small description made from flakes, and comprise those known as scrapers, arrow-heads, borers, knives, gravers, etc. Many of these are very small and delicate, while some show on their upper surface a series of transverse flakings which have, at first sight, very much the appearance of elaborate secondary working. A closer inspection, however, shows that such work could not have been produced after the flake had been struck off. Owing to the discovery elsewhere of clusters of similar flakes on a working floor, it has been possible to replace some of them, and by this means it becomes quite clear how this simulation to secondary working, which is often a very delicate ripple surface, came about. The method employed by the makers of this type of object was first to prepare the block of flint selected for operations by working off inequalities and producing an even surface by finely flaking it all over. After this was done the larger flakes were struck off, the more suitable being further manipulated for special purposes Many of these flakes, simply
