VOL. xviii. (2) WATER SUPPLY OF CIRENCESTER I79 



Royal Agricultural College. Marker was surprised to see that 

 they were specimens indicative of Oxford Clay' At his 

 request Taunton sent them to Jermyn Street, where they were 

 examined by Messrs Sharman and H. B. Woodward, who 

 confirmed his (Marker's) conclusions.^ 



Marker naturally became interested, and when, in July, 

 1890, a 9-inch diamond-boring^ was commenced from the 

 bottom of the new shaft, kept a very close watch. 



The Great Oolite was proved in this bore-hole— according to 

 Marker— at between 128 and 130 feet from the surface. The 

 boring was continued into the Great Oolite for close upon 50 feet, 

 and was then abandoned at a depth of 177I feet from the surfaced 



The cores that were drawn were placed at Marker's dis- 

 posal for detailed examination.^ Marker published a vertical 

 section of the beds that were passed through.^ 



From the well and bore-hole sunk in 1890, a sufficient 

 quantity of water was obtained to meet the needs of the time. 



In 1898 the Works of the Water Company were purchased 

 by the Cirencester Urban District Council. 



More water was soon required. Consequently, it was 

 contemplated putting down an 18-inch bore-hole between the 

 two 4-inch holes at the bottom of the " Brewery Well." It 

 was found, however, that the two 4-inch holes had not been 

 bored true : they were out of the vertical and converged. 

 Also, it was discovered that the greater quantity of water 

 supplying this well was not coming from a deep-seated source, 

 but from the gravel-bed. Apparently, the two bore-holes 

 had not proved satisfactory in the matter of obtaining water, 

 so seven holes had been drilled through the side of the well 

 to admit of watej from the gravel-bed !
