per diem. Their gathering ground would extend over 177 miles, 

 and the storeage capacity afforded by the lakes Haweswater, 

 UUswater, and Thirlmere, with some auxiliary reservoirs, which ' 

 they propose would even somewhat exceed the storeage proposed 

 by Mr. Bateman. 



The length of aqueduct for the North Wales scheme would be 

 183 miles, and that from Westmoreland and Cumberland 240 

 miles. 



Mr. Bateman's total estimate is £10,850,000, of which the 

 aqueducts and syphons, to cross vaUeys, take 6,410,000. 



Messrs. Hemans and Hassard's total estimate is £12,200,000, 

 of which the aqueduct, including a tunnel eight miles in length, 

 takes £8,475,000. 



I consider very serious objections arise in the case of both 

 schemes to the long length of open aqueducts which are proposed. 



The cost of covering them would be so great as to render such 

 a construction of them almost impracticable. The water 

 practically would have deteriorated from its native purity in its 

 passage before reaching the Metropolis, and thus the chief 

 argument of the promoters arising from the excellent and 

 unexceptionable quality of the water at the source of supply 

 would be lost. 



No doubt if the Cotteswolds could afford anything like such 

 a supply as the district chosen by Mr. Bateman, their proximity 

 to the Metropolis (one half the distance which his aqueduct is 

 proposed to traverse) would afford a sufficient reason for their 

 selection as a very suitable gathering ground, and I do not 

 think any serious objection could be taken against the quality 

 of the Waters of the Cotteswolds by reason of their hardness, 

 which is not of a permanent character, and is reduced by boiling. 

 Such an extensive supply as that contemplated by Mr. Bateman, 

 the Cotteswolds, however, do not afford, neither do I think that 

 Mr, Bravendek has shewn we may safely depend upon them even 

 for the more limited supply of 100,000,000 gallons per diem. 



That rain waters which have fallen on our Cotteswold Hills 

 are no doubt lost in large quantities for any useful purpose; that
