By the very kind permission of the owners, I was enabled to carry out the excavation of some “floors” at Grime's Graves, in June and July, 1919, with some friends.

At the same time Mr. D. Richardson was clearing the remarkable site which he discovered in the North Field.

The centre of Floor 52 was fifty paces N.E. of the corner of the West Field, and fourteen from the edge of the cart track north of the wood. Twenty yards N.W. of the said centre was Floor 47, nearer to the cart track coming up out of the valley, and with comparatively small flakes and cores, of poor quality. The facets are short, deep, and wide, like those on an implement of the Chelles Period. The shapes of the cores differ from the true Grime's Graves type. At Floor 51 Mr. W. G. Clarke rightly pointed out that these traits were, in part, due to the fact that wall-stone was used. Only in part, however, for floor-stone was also used, as examination showed. The chipped flints in the outer part of Floor 47 lay in the lower part of the humus, 9 ins. below the surface.
