out at tho junction ; and the water is usually softer than that obtained 
from the Great Oolite. 
The older wells of Northampton, St. John's well, and Becket's well, 
at one time of much repute, obtained their water from the Northampton 
Beds.* On the village green at Kingsthorpe there is a copious spring 
called the King's Well, which (according to Morton) has never been 
known either to fail or freeze. Water is obtained from a well in the 
Northampton Beds at Duston (p. 402.). 
At the Kettering waterworks, south-west of Weekley church, water 
was obtained in the Northampton Beds at depths of 21 to 28 feet, from 
two shafts and galleries : the yield amounting to 480 gallons a minute.f 
South-east of Kingscliffe there is a spring called the Seven Wells. 
A spring at Wothorpe, south-west of Stamford, is used for the supply 
of that town : it yields about 100,000 gallons per day and issues at the 
base of the Northampton Sand. 
At Braceborough, the Lincolnshire Limestone yields an abundant 
supply of water. The river, above the Spa, is said to be studded with 
springs for a distance of about 2 miles. A well sunk to a depth of 28 
feet through the Upper Estuarine Clays, yielded water at the rate of 420 
gallons a minute, and this rose to 15 feet above the surface. At Wils- 
thorpe three borings were made to depths of 60 to 65 feet, and the total 
yield was 2,166,246 gallons per day. 
At Well-head, near Bourn, in Lincolnshire, there are natural springs, 
which when gauged in 1874, yielded 4,600,000 million gallons per day. 
At Bourn a well, sunk in 1856, to a depth of 92 feet yielded 567,000 
gallons a day. In 1893 Messrs. Isler and Co. tapped springs at depths of 
78 to 120 feet in the Lincolnshire Limestone, and these yielded 2,592,000 
gallons a day, the water rising above ground. In other places in South 
Lincolnshire, good supplies have been obtained from the Lincolnshire 
Limestone, the water rising from 2 to 20 feet above the surface : as at 
Cawthorpe (depth 110 feet), Morton (93), Dunsby (105-112), Pointon (87), 
Billingborough (87-95), Horbling (87), and Sleaford (120). At Eippingdale 
(130 feet), and Swaton (200), the water did not rise above the surface; 
while at Graby (150), and Hanthorpe (168), no water was obtained. At 
Folkingham a well sunk through the Lincolnshire Limestone to a depth 
of 300 feet, obtained a " variable " amount of water.J No doubt the 
undulations in the rocks modify the underground flow of water. 
Since the above records wore published, I have obtained other accounts 
of wells in the district, from Messrs. T. Tilley and Sons. Thus in a boring 
at Sleaford, at a depth of 156 feet (in the Lincolnshire Limestone) a 
spring was struck, which rushed out of the bore-hole 3 feet above the 
surface, at the rate of 12,000 gallons per hour (see p. 426). In another 
boring, at Cross Key's Yard, Sleaford, water was obtained at a depth of 
81 feet. Wells made at Osbournby (150 feet), Euskington (120), and 
Aswarby (131), obtain their water from the Lincolnshire Limestone, and 
it rises above the surface during part of the year (see p. 426). A well at 
Ruskington Fen obtained water at a depth of 200 feet. 
A well at Swaton, carried to a depth of 260 feet, gets water in the same 
formation ; and I am informed by Mr. Jesse Clare that it flows above the 
surface all the year round, and is distributed by gravitation to the 
village. Another well-boring made by Messrs. Tilley and Sons, in 1892, at 
Heckington, was not so successful : water was found in the Lincolnshire 
Limestone at a depth of 400 feet, and it overflowed at the rate of about 
6 gallons a minute. The water however contained about 127 grains per 
gallon of saline matter, chiefly chloride of sodium. 
At.Wilsford, near Sleaford, the Norclitf spring issues from the Lincoln- 
shire Limestone ; and at Horbling, east of Folkingham, there is a spring 
of some note. A spring at Stoke Rochford, near Colsterworth, south of 
Grantham, issuing from the Lincolnshire Limestone, is said to yield 
a very abundant supply of water.
