Before proceeding to give a description of the silted-up lake of Hoxne, and its contained flint implements, I would wish to express my thanks to Miss Dorothy Garrod, Professor P. G. H. Boswell, Sir Arthur Keith, F.R.S., Dr. O. Erdtman, Professor Henri Breuil, Mr. Alfred S. Barnes, Mr. Reginald Smith, and to Mr. Guy Maynard, for the help they have given me in my researches during 1924–6 at this spot. I am also especially indebted to the British Association, the Percy Sladen Memorial Fund, and to Mr. Henry Balfour, F.R.S. for providing the funds to pay for the labour employed. The work of excavation was carried out under my supervision, by my trained digger, John Baxter, assisted by one of the men employed in the brickfield at Hoxne, and every care was taken to obtain a trustworthy record of the exact position each humanly flaked flint, or other specimen, occupied in the geological sequence.

The implementiferous deposits of Hoxne are justly famous throughout the archæological world. In the year 1797, there was living at, or near, this place, one, John Frere, who evidently took a keen, and remarkably astute interest in the question of the antiquity of man. There is no doubt that then, as now, a brickfield existed at Hoxne, and Frere's attention was drawn to a quantity of flaked flints which were being turned out by the workmen, at a certain level below the brickearth. To realise the significance of what follows, it is necessary to grasp the fact that, in 1797, next to nothing was known regarding ancient flint implements of any kind, and least of all about those which we now know were made by Lower Palæolithic man.
