NEAR TETBURV. GLOUCESTliRSHIRE.

In 1914-15 a deep boring was made by the West Gloucester- 
shire Water Company at Sliipton Moyne, a village two miles 
due south of Tetbury. The precise site is three-quarters of a 
mile south-east by south of Shipton Moyne Church. 
To be exact, a well was sunk to a depth of 47 feet 2 inches, 
then a percussion boring to 100 feet 6 inches, after which a 
rotary boring was made down to a depth of 286 feet 6 inches. 
Samples of the rocks passed through by the well, and, as far 
as the method of boring permitted — by the percussion boring — 
were kept and labelled as to the depth from which they had 
been obtained by Messrs Thomas Tilley & Co.’s foreman ; but, 
in order to have as complete a core as possible, a bore-hole 
— called “ No. 2 Bore-hole ” on Messrs. H. Rofe & Son’s 
plan — was put down forty feet away from the well and cores 
were drawn from 12 feet 6 inches (from the surface) down to 
58 feet. Thus no cores were drawn from between 58 feet and 
100 feet 6 inches — the latter the depth at which the rotary 
boring commenced at the bottom of the percussion boring. 
As the site of the bore-hole is some thirteen miles from the 
nearest portion of the Cotteswold edge at Upper Kilcott, near 
Hawkesbury, is close to the main outcrop of the Cornbrash, 
and passed through 
67 ft. 6 ins. of Forest Marble beds, 
84 ft. 8 ins. of Great Oolite, 
62 ft. 2 ins. of beds best described as “ Passage Beds,” 
and penetrated 72 ft. 2 ins. of Fullers’ Earth, 
it is obvious that the information obtained is of considerable 
use to those concerned with questions of water-supply in this 
part of the Cotteswolds and adjacent district to the east, and 
of great value to those interested in the Jurassic rocks.
