favoured me with a copy of the bore, and samples of the strata 



gone through. The hole was 15 inches in diameter, and was 



made by Messers. Mather and Piatt, of Salford, with their 



new apparatus for boring. On the whole work the workmen, 



I am informed, averaged from eight to nine feet a day, and 



during their passage through the upper new red sandstone, 



they generally went three feet per hour ;— certainly a very 



extraordinary speed- for such a bore. The following is a list 



of the beds gone through : —

Now, in the above section the upper permian beds, namely, 

 red clays (marls) with thin beds of limestone, are 128 

 feet in thickness—just about what was expected ; but the 

 lower beds, which, when last seen at Collyhurst, two miles and 

 a-half to the south-east, were 350 feet in thickness, and at 

 Patricroft, on the west, within one mile and a-half of Seedley, 

 were 21 feet, only proved to be 12 feet 6 inches thick. These 

 beds bear no resemblance to the soft crumbling sandstone at 

 Heaton Mersey, Beet Bank Bridge, and Collyhurst, but are
