 measures. 



The iron mines occur in the limestone near the 

 junction of that deposit, with the upper new red 

 sandstone, but I have heard of none of them tra- 

 versing the latter rock. Up to the present time 

 they have chiefly been found in Lindal, Dalton, 

 •and Stainton, and their extent towards the east 

 has not yet been thoroughly proved. 



One of the richest deposits of iron, is situate on 

 Lindal Moor, in the estates of the Duke of 

 Buccleuch and Lord Muncaster, and by those 

 noblemen let at royalty rents. It is partly an 

 open work. The fissure or valley in the lime- 

 stone, where the iron occurs, must be from forty 

 to fifty yards in width, and runs in a direction 

 from north-west to south-east. The dip of the 

 rock is east north-east. On the north wall of 

 the vein, the limestone is coated with kidney

 paste, called " Raddle," consisting of nearly 

 pure hydrate of the per oxide of iron, in which

 quartz, and detached pieces of kidney ore. The 

 limestone, composing the walls of the vein, is so
