EXCAVATIONS IN PILLOW MOUNDS AT HIGH BEACH. 221 pottery. Further, they seem to belong to a comparatively deep horizon at the bottom of the surface soil, substantially below the surface level on which the mounds were constructed. I dug many pot-boilers from under the middle of the mounds, quite on the surface of the Bagshot Sand, and below the un- disturbed stony loam. It is not improbable that there may be Neolithic cooking sites in association with some of the many springs which are thrown out along the margin of the Bagshot Sand. The Flint Implements.—It is very likely that these belong to the same deeper level as the pot-boilers, and that they were accidentally picked up with the soil. They are less numerous than the pot-boilers, and I did not actually find more than a very few flakes along the pot-boiler horizon at the bottom of the original surface soil. No implements worth special description were found during the excavations. Some years ago I found a small example of the "Thames pick" group in one of the rabbit holes of Mound B. It is 41/4 inches long and scarcely more than 11/2 inch wide; it is of sub-triangular section, with a transverse "tranchet" blow on one side of the cutting edge. From time to time I have found several minor implements, and many good flakes. Some of these may be contemporary with the mounds, but I think that the majority at least are earlier.1 Mr. W. H. Ryde has also been fortunate enough to find a broken piece of flint saw. It is the middle piece of a flake, finch long, but broken off at either end, skilfully notched along one edge into small teeth at the rate of 28 to the inch. Are the Pillow Mounds Rabbit Warrens? Several old inhabitants of unimpeachable veracity are confident that the mounds were made within their own memory to serve the purpose of artificial rabbit-warrens. One cannot doubt that they remember digging being done, but I feel that it is a long way to carry memory back and yet be sure that nothing existed there previously. It seems to me that it is a feasible I Since the above was written, evidences have been obtained in Loughton Camp (which also is of the Prehistoric Iron Age) which render it more probable that the flint implements found in the pillow mounds may be contemporary.
