really similar to the Grays holes ; those at Brandon were clearly shown to have 

 been made in search of Hints ; here there are few flints, those that exist appear to 

 have been disregarded, and there are no chipping*. In fact, each set of Dene 

 or Dane-holes must be judged by its own surroundings primarily." 



The writer discusses the various theories which may be 

 advanced respecting the precise age of the deneholes, and urges 

 the desirability of further investigation to complete the work 

 begun by the Club. 



Visit to the Deneholes, Hangman's Wood. — The 



Croydon Natural History and Scientific Society having decided 

 to visit the deneholes of Hangman's Wood, Grays, on June 4th, 

 1904, were good enough to invite me to join them. Dr. H. C. 

 Male, the director, had made the necessary arrangements for the 

 descent. We entered the pits by the shaft of No. 4 (Plan of 

 Deneholes, Essex Naturalist, vol. i.). The party appeared to 

 be much interested in what they saw. When in No. 5, an 

 attempt was made to take a photograph, which was unfortunately 

 unsuccessful owing to the variability in the amount of the light 

 afforded by magnesium wire. Reference to the denehole plan 

 will show that No. 2 is a five-chambered pit, the position of the 

 sixth chamber being represented but by a very slight concavity. 

 But when we were working in these pits nothing appeared to 

 give any presumption as to the cause of the absence of the sixth 

 chamber. For the other chambers are rather below than above 

 the average size, and a sixth chamber of more than the usual 

 length might have been made without too near an approach to a 

 neighbouring pit. In June this year, however, the reason for the 

 non-excavation of the sixth chamber was almost certainly 

 revealed by the appearance, in the slight hollow representing it, 

 of an area of a few inches in extent consisting of Thanet Sand, 

 and marking the existence of a " pipe " in the chalk there. 

 These pipes, as every one knows, are extremely varied in shape 

 and in the way they ramify. There is a large one shown in the 

 roof of another part of No. 2, the existence of which no doubt 

 caused the original excavators to desist working at the sixth 

 chamber at the sight of the slightest quantity of sand in the 

 chalk six or seven feet above the floor. — T. V. Holmes, F.G.S.
