that in the space between that spot and Rundle Beck, scarcely 6 miles, 

 there is a difference in its position relatively with this bed of Limestone, 

 of 58 fathoms. How this change of position takes place is no where to 

 be seen, and there are but two ways of accounting for it ; one is by 

 supposing the Whin to cut its way through the beds upwards in its 

 course from Murton Fell towards Rundle Beck, or to fancy the beds to 

 split and divide, and new ones " to put in," as the miners term it. The 

 latter supposition appears to me the correct one. 



Forster's Section, from Newcastle to Cross Fell, was compiled from 

 the experience of different mine workings, and, in the line he took, there 

 are so many, and the intermediate spaces are so well known, that his 

 account may be relied on as generally correct, and it is, undoubtedly, of 

 much practical utility to the Miner and Geologist, but great mistakes are 

 made when we attempt to apply it in other directions. 



If, for instance, we compare it with a section, formed with great care, 

 on the river Gelt,* which runs from the northern part of the fells to the
