244 REPORT ON THE DENEHOLE EXPLORATION there which have been modified from time to time in such a way as to render it impossible to ascertain their age or the purpose of their original excavators. But all persons would unite in considering the collections of pits at Hangman's Wood and at Stankey and Cavey Spring, Bexley, to be deneholes, and would add to them the isolated pits of the same kind scattered singly, or in groups of twos and threes, in the neighbourhood of these larger collections and elsewhere. Nor would many refuse to add to the above the various pits of lesser depth and simpler form, also frequently found in groups of twos and threes, as well as singly, where the chalk is at, or within 15 or 20 ft. of, the surface. Of this last class the pair of pits examined by Mr. F. C. J. Spurrell at Crayford in Kent, which are here figured, Fig. 6, are good examples. It is evident that one of the most distinguishing characteristics of both the above varieties of deneholes is the vertical entrance. This, however, though a leading feature in the chalk counties, is not found in the deneholes of Durham. Mr, R. O. Heslop, an active member of the Newcastle Society of Antiquaries, pointed out to us three or four years ago that an eminent northern antiquary, Mr. W. H. D. Longstaffe, had mentioned these Durham deneholes in his very interest- ing paper on "Durham before the Conquest," read at the Newcastle meeting of the Archaeological Institute in 1852. Mr. Longstaffe, after remarking that the name "Danes Hole" is applied to several hiding places in the county, and that it may perhaps have had its origin in the times of warfare between Saxon and Dane, from their use as places of retreat from the latter, states:—"They are frequent in Hartness, where the struggle seems to have been most bitter, and are described as excavations in the sides of eminences, in those sides from which the most extended views might be obtained." On the map accompanying Mr. Longstaffe's paper, the words are seen "Excavated halls called Danes Holes;" and they are marked as existing on the Magnesian Limestone of South Durham chiefly in the neighbourhood of Embleton, six or seven miles west of Hartlepool. These Durham deneholes or Danes-holes may, of course, have been den-holes constructed during the Danish inroads of the 8th and 9th centuries, or may be excavations of a much earlier date, put to their last important use about that time, there being no evidence as to their approximate age. On the other hand, in the case of one of the Crayford pits already mentioned, Mr. Spurrell's examination showed that it dated from the Neolithic period, and it seems likely
