An analysis of the water was made by Sir Edward Frank- 

 land, who said it was one of the purest waters he had ever 

 analysed. 



Permanent hardness . . 79 degrees 



Temporary ,, . . 172 



Total = 251 degrees 



The bore hole proved only Triassic rocks : sandstones with 

 occasional beds of conglomerate, especial'y in the upper por- 

 tion. The well proved very similar beds so far as it went. 

 Detailed records of the rocks passed through are preserved in 

 the City Surveyor's Office. 



Madams Wood Reservoirs. — These reservoirs are situa- 

 ted three miles from the Newent Pumping-Station and eight 

 miles from Gloucester. The top water level is 250 feet above 

 Ordnance-datum. The first reservoir was constructed in 1894- 

 95 : the second in 1901. 



Storage capacity : No. i. 600,000 gal'ons 

 No. 2. 1,200,000 



Total 1,800,000 gallons 



Ketford Boring. — Although a very large supply of water 

 is obtained from Newent, in order to make provision for the 

 future requirements of the City, and ensure that as the popula- 

 tion increases, there shall be a corresponding supply, further 

 powers were sought and obtained (2 Geo. V. ch. xcii.) in 1911, 

 for the construction of additional works at Ketford, in the 

 parish of Pauntley. 



A boring (fig. 3, page 351) was commenced near Ketford 

 Bridge on October 7, 1910. 



The cores down to a depth of 353 feet had a diameter of 

 18 inches ; but from 353 to 359 feet they were smaller, as a 

 I4j-inch crown was used for the drilling. Portions of the core 

 were ground to sand ; but the specimens of the hard portions 

 that I selected for preservation in the Museum are typical 

 examples of the beds from which they were derived.
