BROUGHTON. 



The lower part of this township, in the valley 

 of the Irwell, is situate on sand and gravel (No. 1,) 

 and the higher and more northernly portions on 

 fine sand (No. 2). The only place where the 

 brick-clay (No. 3) occurs, is a strip of land run- 

 ning by the side of the Bury New Road, from 

 the end of Broughton-lane to Mount Broughton, 

 and extending over the rising ground about Stony 

 Knolls. With this exception, the district is on a 

 dry bottom, and well drained by the nature of its 

 subsoils.

 yards before the Till is reached. That the latter 

 deposit does underlie the sand, is proved by the
