﻿546 MK. A. WILMOEE ON THE CAKBONIFEROTJS [Nov. I9IO, 



From Warre] Quarry to the first beds of Fogger is about half a 

 mile. The height in the two cases is almost the same. The dip 

 varies between 15° and 18°. Hence, the possible thickness of 

 strata between the Caninia gigantea beds of Warrel and the white 

 crinoidal limestone of Fogger may be about 700 feet. The similar 

 beds of Swinden Gill Head, however, with an all but identical fauna, 

 seem to come very near to Pendleside Beds, which in their turn 

 usually begin almost immediately above the shelly crinoid breccia 

 that so often forms thick beds at the very top of the Carboniferous 

 Limestone. 



But, of course, in a drift-covered country, with exposures scattered 

 here and there, with so much change in the observed dips, and with 

 so many direct evidences of disturbance, any such estimates as the 

 above must be received with great caution. 



(2) The Eshton-Hetton Anticline. 



Under the above heading I propose to describe all the exposures 

 which I have noticed on Eshton Moor, near Winterburn, and near 

 Hetton and Rylston. 



The exposures near Crag Laithe and Throstle Nest 

 (Eshton Moor). — About half a mile east of Bell Busk village, 

 and on the left bank of the River Aire, are small scars of limestone 

 culminating in a knoll- like hill in which is an old quarry. A very 

 interesting series of beds is shown in the Crags, in the quarry, and 

 in the pastures immediately east and north-east of the Crags and 

 the quarry. 



In the Crags the beds are well-bedded and relatively undisturbed, 

 with a south-south-easterly dip at an angle of about 8°. The Crag 

 Laithe Quarry beds come at the top of the series. The succession 

 is as follows : —
