Secondly. — I will endeavour to define the limits of the 

 area, from which a supply of water could he obtained by 

 Artesian borings in the strata, and will point out the impe- 

 diments, natural and artificial, that exist on the surface of 

 the district, and which greatly obstruct the free passage of 

 the water into the formation, and will also attempt to show 

 the maximum quantity that actually passes into the mass 

 of the strata. 



Thirdly. — I will shew the relation in which the division 

 of the new red sand stone of this district stands with respect 

 to the inferior and outlying formations, and the impractica- 

 bility of obtaining from those formations any supply of 

 water by Artesian or other subterranean operations. 



Fourthly and lastly. — I will next endeavour to point out 

 the most favourable places from which a supply could be 

 obtained from the strata, and the improper positions of the 

 present companies wells for furnishing, for any length of 

 time, their present supply, and refer to the proofs of the 

 gradual exhaustion of the strata of their water, and the 

 certainty of a period arriving when that supply must nearly 

 cease, and from these draw the conclusion that there is an 

 absolute impossibility of obtaining from the neighbourhood 

 an ample supply of water for the wants of our rapidly 

 increasing population. 



In the first place, then, the Town of Liverpool and the 

 adjoining neighbourhood are situated on the upper division 

 of the Poikilitic group, called by German geologists the 

 Bunter Sandstein, and by the French the Gres Begarre. 



It also occupies almost the whole County of Chester, 

 and other extensive districts on the Western side and 

 middle of England. In this neighbourhood, and on the 

 other side of the Mersey, the division consists of three 

 subdivisions : the lower red, the middle yellow or white, 

 and the upper red. The aggregate thickness of the whole, 

 when entire, may he set down at from 600 to 1000 feet.
