338 MR. H. H. ARNOLD-BEMROSE ON THE GEOLOGY OF [Aug. I903, 



(ii) The granular and in part oolitic structure of some of the 



limestones, 

 (iii) The probable thinning-out of the volcanic tuff in a northerly 

 direction from the village of Tissington. 



The cuttings between Parsley-Hay Station and Buxton were 

 completed before my attention was called to the new railway, 

 consequently they have not been carefully examined. The dip 

 of the limestones is generally small, and the cuttings are of no 

 great depth nor length. In one of them, the vesicular lava which 

 is mapped by the Geological Survey near Haslin House (about 

 1 mile south of Buxton) wa3 seen north-west of Staker Hill. 



II. Description of the Cuttings. 



9. Crake-Low Farm. 



Separated by a bank of red soil from the Crake-Low cutting 

 (No. 8 in my previous paper) is one in which a thickness of about 

 30 feet of limestone is seen. The beds are contorted, and form 

 a small fold the axis of which runs nearly due north and south. 

 They consist of cherty limestones, which are often dolomitized and 

 separated by thin partings of shale. 



10. Newton Grange. 



The railway has been cut through a ridge or elongated dome, 

 which forms a well-marked feature in the landscape. The longer 

 axis runs north-north-west and south-south-east, while the cutting 

 is parallel to the shorter axis, and shows a section with a 

 fine anticline in the Mountain - Limestone. For the first 80 

 or 90 yards the railway passes through shales and thin beds of 

 limestone which are greatly contorted, then through a thick bed of 

 limestone and alternations of shales and thin limestones, which 

 mark the passage-bed from the Yoredale Series to the Mountain- 

 Limestone. The dip is at first towards the east ; with a few minor 

 contortions, the beds roll over and settle to a south-easterly dip, 

 which is maintained until we reach the centre of the dome, 

 where the beds become horizontal, and then dip in a north-westerly 

 direction. 



The following measurements were taken from above downward. 

 No attempt was made to measure or estimate the thickness of the 

 contorted and rapidly-weathering shales at the southern end of the 

 cutting. A well-defined bed of limestone, white and fresh on one 

 side of the cutting, but brown and partly decomposed on the 

 opposite side, was the topmost of the beds measured.
