The volume of water is stated by Mr. A. Timmins to have increased 

 much on reaching the solid rock at 289 feet from the surface. 



No section of the rock is visible very close to the boring, but as Upper 

 Mottled Sandstone is seen both to the N.E. and S.W. of it, the rock first 

 inet with probably belongs to this formation, and is so represented on the 

 map of the Geological Survey. These beds reach a thickness in the 

 district of above 400 feet, and as the first 289 feet consisted entirely of 

 drift, the upper beds here have doubtless been denuded away, and only 

 about 111 feet would probably be left. The boring penetrated 185 feet of 

 rock, consisting of red and brown sandstone, at the bottom of which was 

 a coar.se brown conglomerate, which is probably the conglomerate I found 

 occurring at the top of the Lower Keuper Sandstone, near Orrel, east of 

 Waterloo and north of Liverpool. 



Well and bore-hole at the works of Messrs. Bayley & Craven, at 

 Ayecroft, Pendleton, near Manchester. Well 32 feet deep, 6 feet diameter. 

 From bottom 2 tunnels diverge, and extend about 50 feet, containing 

 when full upwards of 500 cubic yards. 



The bore-hole is 403 feet deep from the bottom of well ; the first 312 

 feet is 18 inches' drain ; the remaining, 91 feet 15 inches. 



The whole depth is in New Red Sandstone, 403 feet. 



This well yielded upwards of 5,000,000 gallons per day, on Novem- 

 ber 28, 1859.

Bore-hole at Allford Green, one mile east of Childs Ercall. Carried 

 out for Mr. Reg. Corbet by Mr. A. Bosworth. Obtained by Mr. J. Dickin- 

 son, H.M. Inspector of Mines.

 Some further particulars of the Leamington Waterworks are given by 



Mr. G. B. Jerrara, C.E., engineer. 



The wells are situated on the north-cast side of the town, at the foot 



of the Newbold Hills, about 214 feet above the level of the sea ; the deepest 



boring IS 248 feet deep, or 34 feet below it. 



A 20-feet well is carried to a depth of 113 feet, An adjoinino- well
