no break in continuity(withthe exception of two small faults), 

 dipping W. or W.S.W. at an average of 14°. But, at the point 

 named, about 50 yards west of Slade Lane, the base of the 

 bright red sandstone is seen resting on, apparently, an 

 eroded surface, sloping westward at io°, of green and deep 

 purple marls, and purple dark grits. These beds overlie 

 several beds of the Levenshulme limestones with Spirorbis 

 carbonarius and a band of calcareous ironstone, at the 

 lowest point yet reached, which are, in my opinion, the 

 Ardwick series of the Upper Coal Measures. They dip 

 at a much higher angle than the overlying red-beds, 

 which may indicate the presence of a fault, as suggested 

 by Mr. Brockbank in 1883."

Manchester Coal-field. 



The cutting at Slade Lane has laid bare the outcrops of 

 the several bands of limestone described in 1883, the upper 

 limestone being flat bedded, from 2 to 8 in. thick, and 

 plentifully mottled with circular greenish markings, which 

 are popularly known as "fish eyes" in other localities. The 

 lower seams are thicker, and contain great numbers of 

 fossils. 



The upper surfaces of the outcrop limestones were 

 found to be much eroded, and many glacial scratch marks 

 were clearly seen upon them. Boulders of granites, green-
