Uuouch the district, and may be connected with the fault at Addy Wood in the 

 Pcrmians, or these beds may be thrown in by a very local trough fault, which view 

 is supported by the small supply of water met with. 



6. East Cowick. Village supply. Boring 4 inches diameter, 90 feet deep. 

 Through ' pan sand' (drift sand cemented by oxide of iron) and very soft red sand- 

 stone. Water good. Surface level 20 feet above O.D., bottom level 70 feet below CD. 



7. West Cowick. Village supply. Depth, diameter, and section same as No. 6. 

 Surface level 25 feet above O.D. Site close to ' Bay Horse Inn.' 



8. West Cowick. Trial boring N.N.W. of No. 7. Surface level, 25 feet above 

 O.D. ; depth, 80 feet. Marl, &c., here pointing to some disturbance. 



9. West Cowick. Hartley's Brewery. Surface level, 25 feet above O.D. ; depth, 

 1,050 feet; bottom level, 1,025 feet below O.D. 



Section (1,050 feet) : — FePt. 



Red gravel 55 



Red sandstone 623 



Beds not reported 372 



Total hardness of water, 14'0°. 



10. South Field. Trial boring for Goole supply, south of Park House F\'irm. 

 Surface level, about 15 feet above O.D. ; depth, 152 feet; level of bottom of bore- 

 hole, 137 feet below O.D. Water stated to be good. 



10a and XOh. Trial borings for Wakefield Corporation, west of Heck railway 

 station, where the sandstone rock is visible. Surface level, 40 feet and 50 feet above 

 O.D. The late Dr. Letheby reported as follows on these samples, on October 22, 

 1875. Sample A, bore-hole in Mr. Drewer's land, taken at 12 P.M., September 16, 

 1875; Sample B, from No. 2 bore-hole, taken October 13, 1875: — 



This water is thoroughly free from organic impurity and of moderate hardness, and 

 in every way thoroughly suited to be a source of public water supply. 



11. Pontefract Water Supply Well. One mile S.W. of Aire, at Chapel Had- 

 dlesey, which is the highest point to which the tide flows. Surface levels, 25 feet 

 above O.D. 



Dr. Franklin Parsons, of the Local Government Board, was good enough, in 

 February 1892, to give some very valuable information to the Committee as to the 

 quality of the water of the Goole district, from which report the following abstract 

 has been made : — 



The water from the red sandstone at Goole is of a peculiar character, containing 

 a large amount of free ammonia, of solid matter and soap-destroying salts, chiefly 

 magnesia and iron in a ferrous state ; though clear at first, it afterwards throws down a 

 rusty sediment, at the same time losing its chalybeate taste and smell, which at first 

 is very apparent. At Selby, and to a less extent at Rawcliffe, this is not the case ; 

 and be points out that, in the first case, the sandstone is covered with impermeable 

 clays ; in the second, the gathering ground is either bare rock or rock covered witli 

 porous gravels; and justly observes that the water in the red sandstone is 'aerated 

 in one case and not in the other.'
