The galleries had arch-shaped roofs, and varied in height from seven to twelve feet, the workings inclining downwards and becoming deeper as they went north. Some of the galleries widened out at the ends, and formed small chambers, and in one or two instances it was observed that the roof of the chamber was considerably higher than the gallery which led to it. The entrance appeared to have been from the southern end, but as the earth had fallen, or had been filled in there, nothing decisive could be said as to the exact position of the original entrance. The marks of the picks were as plainly visible as though just made, and one pick appeared to be "square-pointed," so to speak, and half an inch broad, whereas another was only a quarter of an inch broad. Under Mr. Alfred Brooks' guidance, Mr. Spurrell made a careful examination of these chalk workings, and he came to the conclusion that they were comparatively modern, and had no necessary connection in point of date or intention with the Dene-holes in Hangman's Wood and elsewhere. It was suggested with some show of probability that the galleries may have been used as store-houses for smuggled goods, and that entrance was obtained by a short shaft from the field above the workings. No trace of human or other occupation could be detected, with the exception of a small heap of bones, apparently those of a bird. On the morning of the day of meeting several members journeyed down to Grays by an early train, the party including the conductors, Mr. Worthington G. Smith, Dr. Cory, Mr. W. Crouch, and the Secretary. We were met at Hangman's Wood by Mr. Biddell (agent to Capt. Wing- field, the owner of the wood), who had very courteously given full permission to the Secretary to conduct any operations considered neces- sary; also by Messrs. Herbert and Alfred Brooks, of the Grays Chalk Quarries, whose firm had furnished a horse and cart, with the requisite " tackle," and three of their best workmen to handle it. Although the wood is not more than a quarter of a mile square (see Plate II.), it con- tains evidence of the former existence of at least seventy-two Dene-holes ; the majority of these are " filled up," either naturally or artificially. The filled-up examples are about 30 feet across, and 6 or 8 feet deep, and form deep basin-like depressions. In several instances the whole cavern beneath had evidently fallen in, and quite a chasm in the soil bore witness to the calamity. Many of the closed examples are probably not entirely filled up from top to bottom, but the falling in of boughs of trees, showers of leaves, and the rain-wash of Thanet-sand, gravel, &c., from the sides, has gradually made a kind of plug or cork, above which more soil has accumulated. We were told, in confirmation of this view, that a "filled- up" hole had recently opened itself again, the plug of leaves and soil dropping to the bottom of the shaft. Each open hole presents a funnel- shaped aperture, some '20 feet across, gradually shelving down to a
