Extract

About forty-two years ago Mr Archibald Geikie (now Sir Archibald), then an energetic member on the staff of the Geological Survey, propounded and advocated the doctrine that the change in the relative level of sea and land, indicated by the 25-feet raised beaches which have been long known to geologists as fringing the winding shores of the firths of Central Scotland, took place subsequent to the occupation of the district by the Romans. Further researches, together with a more careful examination of the archaeological phenomena on which Sir Archibald mainly relied as evidence, convinced later observers that the facts did not justify this conclusion. Hence for some years I have been under the impression that the post-Roman theory was abandoned, not only by the general body of geologists and archaeologists, but, as I understood, by the author himself. The following statement of opinion on the subject, recently urged in the interests of the Trustees of the British Museum by a distinguished Professor of Geology, and one who has had exceptional opportunities of making himself conversant with all the factors of the problem, will, however, show how wide of the truth that impression must have been.

The socket is formed by the backward folding of the iron, the edges only partially meeting, and in it the handle was fixed by a rivet. From its appearance, it might belong to comparatively recent times.
