388. REPORT— 1885. 
The whole of the above boring appears to be in the Kimmeridge clay. 
Mr. Dickenson, F.G.S., in H.M. Inspector of Mines Report for 1881, 
describes a boring, 1,140 ‘feet deep, put down west of Horncastle, at a 
point situated on the Kimmeridge clay, near the base of the Cretaceous 
rocks, which was carried to a depth of 1,140 feet, and is stated to have 
reached the Triassic sandstones, in which a brine spring was discovered. 
In this case the Kimmeridge clay, Lower Oolites, Lias, Rhzetic, and Keuper 
marls must have been penetrated. 
At Stamford a futile boring for coal was put down by the late 
Marquis of Exeter to a depth of 500 feet, which, commencing at a 
similar geological horizon to the two last described borings, failed to 
reach the base of the Lias at that depth. 
A boring at Boston Market Place has already been described in the 
Report for 1878; some further details communicated to the Royal 
Society may be found in the ‘Phil. Trans.’ vol. lxxvii. The well was 
sunk in 1747 to a depth of 186 feet, and deepened in 1783 to its present. 
depth of 478 feet.
