BORINGS AT HULL.
In
connection with their water supply, Messrs. Needlers, Ltd., have recently put
down three borings at their works in Bournemouth Street, Hull, about a mile
and a half north of the Humber. The following details refer to the deepest
boring, which, of course, did not penetrate the chalk, but merely went so far
as was necessary for the water supply :-

The flint beds indicating the middle chalk was met
with, and Mr. J. Rickatson, the firm's architect, states:
"Soft loose chalk was found at a depth of 45 ft. below
our yard level, the chalk becoming harder the deeper we bored. The layer of
flint found at 199 ft. was particularly hard and about 2ft. in thickness.* We
found no very great fissures or cavities in the chalk, it being fairly close
throughout the whole depth. We bored for three wells. One was bored to a depth
of 150 ft., 6 in. in diameter, one to 160 ft., 9 in. in diameter, and a third
one to a depth of 200 ft., also 9 in. in diameter. We found water in fair
quantities at about 98 ft., but there not being sufficient at any depth we
bored deeper. The 6-in. well supplies about seven thousand gallons per hour,
and the two 9-in. wells about nine thousand gallons per hour."--T. S.
