68 A. J. Pickering—Borings for Water 
of including the Bartonian and the Ludian in the Middle Eocene, 
and of only beginning the Upper Eocene with the Tongrian. The 
stratigraphical divisions adopted in Europe correspond to marked 
oscillations of shore-lines, and their delimitation is easy. It is not so 
in the Mediterranean Basin and especially in its southern part, which, 
during the whole of the Eocene period, was a region of continuous 
sedimentation. I have thought that the sea-urchin faunas could 
help us to establish subdivisions, and have given the result of my 
researches without stopping at simple questions as to where the 
brackets representing individual divisions should be drawn. 
I am greatly indebted to Dr. W. F. Hume, F.G.S., etc., Director of 
the Geological Survey of Egypt, for kindly translating this paper 
into English. 
V.—On two Bortnes ror Water at Hinckiey, LEICESTERSHIRE. 
By A. J. PICKERING. 
HOUGH Hinckley is now possessed of an excellent supply of 
water brought from the Lower Keuper Sandstone of Snarestone, 
in North-West Leicestershire, up to 1891 it had an unenviable 
reputation for abortive water-schemes. Some £20,000 had been 
spent in considering eighteen different propositions and in carrying 
out three deep borings within a few miles of the town. During this 
time six consulting engineers were called in by the local authority. 
All these schemes failed, not through any lack of water—for this 
was obtained from the Waterstones of the Lower Keuper in almost 
unlimited quantity—but because it was found impossible to shut 
out the chlorides and sulphates from the gypsiferous Keuper Marls 
through which the borings passed. 
Recently two attempts have been made by private firms in the 
town to obtain a supply of water from the Upper Keuper Sandstone, 
but unfortunately these schemes have been abandoned without satis- 
factory results. 
The first was carried out for Messrs. Atkins Bros. at the rear of 
their factory in Bond Street in the centre of the town. Boring was 
commenced in July, 1913, from the bottom of an existing well 
41 feet deep. This had up to late years yielded an excellent supply 
from the Drift deposits (here about 135 feet in thickness), but had 
gradually been drained, probably by the sinking of deep foundations 
in the lower levels of the town and by extensive building operations 
in the higher levels. This latter would have the effect of diminishing 
the quantity of rain-water making its way into. the water-bearing 
drifts. In this boring the jumping-chisel method. was employed 
throughout; consequently the thicknesses of the beds were somewhat 
difficult to ascertain. In the following table they must be taken as 
only approximate. Operations were abandoned in 1914 after repeated 
attempts to recover a boring-tool, and through the falling-in of the 
unlined portion of the borehole. 
The following is the section :—
