Mr. Bradbury did not think the strata favorable for coal, 

 therefore he proceeded no further with the bore. It is doubt- 

 ful to me whether the lower new red sandstone had been per- 

 forated, and the coal-measures reached, especially as the 

 former has been since proved to be of much greater thickness 

 than the whole of the sandstones in the lower part of the 

 section at Jericho Clough. 



A short distance below Waterhouses, the coal-measures, 

 most probably part of the middle field, are seen in the bank 

 of the river, dipping westwards at an angle of 60°. 



About a mile to the north of the two last-named bores, Mr. 

 Henry Walmsley has bored in his estate at Failsworth, and 



found the following strata* : — 



ft. in 



Drift deposits 120 



Red marls 6 4 



Red sandstone 333 



458 4 



The last-named rock was not perforated, therefore it is 

 difficult to determine whether or not it was the lower new red 

 sandstone or the upper new red sandstone, but the red marls 

 lying on the top of it would rather lead one to suppose that 

 it was the former. 



* For this boring I am indebted to the kindness of my friend Mr. Booth, 

 the mining engineer of the Oak Chamber and Chadderton Collieries, Oldham.
