 The problem still awaits solution. 



Leaving- this, the Dale Beck was crossed, the Fox Holes 

 providing- the next point of interest. It showed a most in- 

 structive section of the Carboniferous Basement Bedscontaining- 

 bands not seen in other sections. It was described as follows 

 by the late C. I). Hardcastle :—* 



'Solid limestone, coloured with Silurian mud.' 



'Alternate bands of conglomerate and limestone, former 

 becoming finer in upper parts.' 



'Coarse conglomerate, 2-3 feet.' 



'Limestone with Lithostrofion basalt ifornic, 4-6 inches.' 



' Limestone and calcareous shale, about 3 feet.' 



' Cla_\e}- shale, about i foot. ' 



' Iron-stained coarse conglomerate, about 2 feet.' 



Unconformity. 



' Roughl}- cleaved slates.' 



Various fossils were obtained from the limestones here, and 

 at one or two other places lower down the \ allex' where they 

 were exposed. 



Although it had been amongst grand scener_\- all the da\ , at 

 Beezley's the party paid its sixpences to see the 'scenery.' 

 This may savour of vandalism, but there is little cause for 

 complaint, for, were it not that the lessees have made good and 

 safe paths, the glorious scener}- of the lower part of this dale 

 would be almost inaccessible. For some distance the walk was 

 over the edges of the slates and grits, and the magnificent 

 gorge and beautiful waterfalls were much admired. Near 

 Ing'-leton an igneous d\ke, variously described as mica-trap, 

 minette, and kersantite was seen crossing the bed of the 

 stream, but the water was rather too deep to admit of a close 

 inspection. A nearer view of tlu' Mi-al-bank quarry, mentioned 

 in the early part of the paper, with a thin bed of coal in the 

 limestone, completed the da) 's work. Within such a small 

 area in our county it would be almost impossible to lind a 

 better exposition of such imjjortant geological jjhenomena.
