24 DE RANCE : UNDERGROUND WATERS IN LINCOLNSHIRE. 
passes a yard underground ; it probably would average an inch and 
a quarter per acre, leaving a balance of three inches and three-quarters 
for drinking purposes, necessitating an area of one acre to give the 
quantity of water required by ten persons daily, so that looking to 
the acreage of the county of Lincoln it should be able to supply no 
less than six million persons from underground sources, whilst its 
population is under half a million. Its inhabitants therefore should 
be very amply supplied, but this is far from being the case through 
the underground stores being seldom utilized. 
COLLINGHAM. 
At South Scarle, nine miles S.W. of Lincoln, and half way 
between that city and Newark, on the Nottinghamshire side of the 
county boundary, an unsuccessful boring for coal gave very important 
results as regards the character of the strata and its water-bearing 
capacity. 
A feeder of water was met with at a depth of 134 feet in the 
Keuper Sandstone, running 11 gallons per minute, and another 
occurred at 950 feet, running at 50 gallons per minute, in the same 
formation. The last is stated to have risen 52 feet above the surface. 
These artesian waters are separated from the water in the Bunter 
Sandstones beneath by intervening shales, but there is every reason 
to believe that the whole of the sandstones, from 958 feet to 1500 feet, 
are similarly charged with water, absorbed as rainfall, in the magni- 
ficent gathering ground between Retford and Worksop, an area 
capable of supplying millions of gallons of pure water daily, and at 
present practically untouched. The temperature taken in the Scarle 
bore-hole points to the free passage of water in the porous rocks 
beneath, rising from 69 deg. on the base of the Keuper marls to 691 
deg. at the base of the Keuper sandstone, and to no less than 73 deg. 
in the water flowing off the top of the Permian upper marls. I have 
no information as to the diameter of this bore-hole at the surface, 
but at the termination it was only 0*9 of an inch. I presume it is 
not now available for waterworks purposes, and any future boring to 
reach the required depth, and give a proper supply, should not be 
less than 24 inches at the commencement.
