Then succeeds a series of black shales with thin limestones, mud- 

 stones, and cement-stones, up to the base of the Pendleside Limestone. 



The following section is seen in the stream west of Pendleton 

 Hall, wher&the road crosses the stream : —

These beds dip at 15° south-south-eastward, and are about 

 570 feet below the limestone mapped as Pendleside Limestone. 

 The section ends at the small bridge from the road to the farm, and 

 higher up the stream the shales are obscured by Drift until the 

 Pendleside Limestone is reached. South-west of this point the lime- 

 stone-feature rapidly dwindles away, just as it does at the north- 

 eastern end of the hill, the last exposure in this direction being the 

 little quarry on the road beyond Lanehead, west of liavensholme, 

 where it has been quarried. Farther north-east, along the flanks 

 of Pendle Hill, the series seems to lose its feature-making character 

 and to die away into the shales and thin limestones. 



On the opposite side of the synclinal trough of limestone east 

 and south of Waddington Fell, the Pendleside Limestone is not 

 well developed, but fragments which we obtained at the old quarry 

 of New-a-Nook, south-west of the Moorcock Inn, "Waddington Fell, 

 appeared to be very similar in character and composition with those 

 of the Pendleside Limestone. 



The brooks and streams which flow south-south-eastward from 

 Waddington, Easiugton, Grindleton, and Bradford Fells show a 

 series of black limestones and shales. It is difficult to obtain 

 anything like a continuous section in this district, as the beds 

 are so contorted, and the strike is subject to rapid alterations 

 in direction. Beds of limestone, varying from 6 inches to 15 feet 

 in thickness, are seen with beds of shale, also of varying thickness, 

 between them. Fossils are extremely rare, a single lamelli branch 

 (Ctenodonta Icevirostris), fragments of encrinites, and a coral only 

 having been found by Mr. Lomas, who kindly examined the sections 

 for us. Speaking of these limestones in the Geol. Surv. Memoir on 

 the 'Geology of the Burnley Coalfield' 1875, p. 18, Mr. Tidderaan 

 says : — 



' The Lower Yoredale Grit being absent over a good part of this district, these
