Hangman's Wood.
A History and Guide to the Hangman's Wood Deneholes, by Mr.
Edward Biddell, was published last year, in which there are two
photographs of scenes below the surface. One is styled
"Interior of caves between Nos. 1 and 14 on plan." In the
ground plan of our Denehole Report these pits are numbered 3
and 9. No 3 of our plan was the pit from which our excavations
were made in three different directions. When endeavouring to
get from No. 3 to No. 9—the latter being a closed pit—we could
only order the workmen to tunnel towards the shaft of No. 9, as
we had no means of knowing the positions of its chambers.
However, it soon became evident that there was a chamber to
the right. On entering it we found the partition between the
two pits very thin, though complete. But since cur exploration
ended, some mischievous persons have made a hole in the
partition nearly circular in shape and about 6ft. in diameter.
This is well shown in the photograph. A still more important
injury done to No. 3, since we used it as the headquarters of our
exploration, is the removal of the mass of chalk between the
hole between two chambers (marked x in our plan) and the shaft,
an injury which, besides obscuring the original shape, decidedly
lowers the stability of the pit. This is the more important
because as No. 3 was the centre from which we worked, it is
naturally the most suitable for descent, and the apparatus for
that purpose has accordingly been fixed above it.
