Miscellaneous Notes on Deneholes. 101
V. Notes on a Pit in Joyden's Wood, visited November 10th, 1883.8
I was also indebted to the Sidcup and Crays Field Club for
a pleasant clay in Joyden's Wood at the above date. We then
descended into a pit more singular than any I had hitherto
seen. It is situated near the eastern margin of Joyden's (or
Jorden's) Wood, and about 460 yards due east of the
"summerhouse" marked on the six-inch Ordnance Map.
Fig. 5.—Pit in Joyden's Wood, 460 yards east of Summerhouse.
Scale 40 ft. to the inch.
We found that the Thanet Sand in its shaft only attained a
thickness of 24 ft., instead of the 40 ft. to 60 ft. of shafts in
the westerly parts of the wood. A glance at the map showed
the existence of open chalk quarries about 280 yards away in a
south-easterly direction.

in, which "it is thought best to add to the notes. The whole has been
carefully revised by Mr. Holmes.—Ed.]
