Dr. C. B. Plowright has described a number of rough-hewn instruments of flint from what seems to have been the site of an ancient flint manufactory on Massingham Heath, in West Norfolk. He has figured several, including a wedge-formed implement like Fig. 28, and one of shoe-shape, not unlike a palæolithic form.[309] An interesting instance of the discovery of a flint celt, merely chipped out, but associated with polished celts, and other objects, is that recorded in the _Archæologia_,[310] and Hoare’s “Wiltshire.”[311] In a barrow opened by Mr. W. Cunnington, in 1802, was a grave of oval form, containing a large skeleton lying on its back, and slightly on one side, and above it a smaller skeleton in a contracted posture. At the feet of the larger skeleton were more than three dozen perforated pins and other instruments of bone, and three celts of white flint, two of which were neatly polished, with a fine circular edge; and the third was “only chipped to the intended form and size.” With these lay what was apparently a grinding stone to polish the celts or similar implements; and some grooved sandstones, like Fig. 185. About the legs were several boars’ teeth perforated, and some cups made of hollow flints; near the breast was a flat circular stone, and a perforated stone axe, shown in Fig. 141, and two dozen more of the bone instruments. Some jet or cannel-coal beads and a ring of the same substance were also |84| found, as well as a small bronze awl; but it is doubtful to which of the bodies this belonged. It will subsequently be seen that perforated axes similar to that in this barrow are frequently associated with bronze daggers, so that we seem to have, in this instance, evidence of the contemporaneous use of unground, polished, and perforated stone axes at a period when bronze was at all events not unknown in this country. If the chipped celt is to be regarded as unfinished, it may be that the survivors, in burying it, together with the grinding and polishing stones, in company with the original occupant of the barrow, entertained a belief that in some future state of existence he might be at leisure to complete the process of polishing.
