226 REPORT ON THE DENEHOLE EXPLORATION Caves with Vertical Entrances" ("Archaeological Journal," 1881) ; in Mr. T. V. Holmes's papers "On Deneholes" (Trans. Essex Field Club, iii. 49), and "Miscellaneous Notes on Deneholes" (Trans. Essex Field Club, iv. 87), and in Mr. W. Cole's reports of the visits of the Club to Hangman's Wood in 1882 ("Proceedings of the Essex Field Club," iii., pp. 28 and 56, and iv., page 20). —Ed.] Having been empowered by the Denehole Exploration Committee, in the Summer of 1884, to carry on the work at Hangman's Wood, we began operations there on Oct. 13th, and carried them on during the next four weeks. It was then deemed advisable, for many reasons, to leave off work for the season, in the hope of being able to resume it in the following spring. Various circumstances, however, prevented us from going on with it in the years 1885 and 1886. Having been able to continue our investigation this year for a fortnight, and having at length brought it to a certain degree of completeness, we have pleasure in laying before you the following account of our work and its results. In this Report the whole of our labours are described, whether executed in 1884 or in the present year. And in giving this account of them, we have thought it better to state the nature and results of each kind of work in turn, rather than to present the details in chronological order, a confused impression being almost inseparable from the latter course. We began with four men, two above to work the winding-up apparatus, and two below to tunnel through the chalk. Fixing upon the open-shafted pit, styled No. 3,1 as the best base of operations, our first work was to direct the two men below to tunnel in the direction of the shaft of the closed-up pit we have called No. 7, while we our- selves made a section across the conical mound at the base of the shaft of N0.3, on the side most distant from the tunnel. Finding, as the work proceeded, that it was desirable to have more men at work below, we increased the total number to six, and, at last to eight; while we em- ployed the men above, in the intervals of winding, in digging trenches, from two to three feet deep, and about two feet wide,through the surface material. And two of the men usually below were occupied above ground for a day or two in endeavouring to ascertain whether a closed shaft, round whose mouth the surface depression was much slighter than usual, might not have been stopped up by rotting faggots sup- porting but a slight quantity of sand and gravel. For to open out a shaft thus closed would have been a most useful piece of work Not 1 The numbers given to the pits are purely arbitrary, and denote the order in which they were entered during the explorations.
