The escarpment here is of considerable height, but the debris pre- 

 vents the beds from being traced lower down, or their junction with the 

 Red Sandstone being examined. 



We thus see that the two lines of Section Nos. 1 and 2, Plate XXVII., 

 though at right angles to each other, terminate nearly in the same part 

 of the series. The strata in the Section No. 1 being exposed on the 

 sea shore, enables the observer to trace the connection of the Lime- 

 stones with the Red Sandstone Rocks very accurately ; while the 

 debris along the base of the escai'pment above the plain of Carlisle pre- 

 vcints such an examination from being made ; for in no one place along 

 the whole range of basset, from Croglin Fell to the Irthing, could the junc- 

 tion of theLimestoiiebeds with the Red Sandstone be distinctly examined. 



No doubt, perhaps, exists, that the Red Sandstone of Carlisle is the 

 newer Red Sandstone, and probably the great similarity, not only of 

 mineralogical character, but apparently of position also, between this 

 Sandstone and that of the Tweed, may have occasioned the mistake 

 that they are parallel formations, and caused them to be coloured as 

 such in the Geological Maps.
