Zoological Gardens, through Temple Toll-bar 

 to Sraedley Vale, is upon fine sand, (No. 2.) 



In cutting the new line of road from the end 

 of Halliwell-lane to the New Bury Road, at the 

 end of Broughton-lane, an interesting section, 

 showing the relation of the sand, (No. 2,) to the 

 Till, has been met with. In excavating the rising 

 ground, about four hundred yards south of Halli- 

 well-lane, after sinking through two or three feet 

 of clay, twenty-one feet of fine sand, having thin 

 seams of drifted coal in it, was met with ; at 

 the south end the clay thickened, and the sand 

 could not be seen for a distance of about fifteen 

 yards ; after this interval the sand again appeared, 

 and was seen gradually diminishing in thickness, 

 and resting on the main deposit of Till into which 

 it finally passed. 



The general character of the subsoil of the 

 thickly built portion of the township, with the 

 exception of the low part of Strangeways, in the 

 valley of the Irwell, which is chiefly on gravel, 

 (No. l,)is decidedly unfavourable to natural drain- 

 age. In the highest parts of the township in 

 Cheetwood, and near Mount Pleasant, the Till is 

 supposed to reach full twenty-five yards in thick-
