towards the lower end of Bilsdale. Similar insulated elevations are 

 found between Silphoue moor and Saltergate, the most remarkable 

 of which are Langdale End and Blakey Topping. These hills are 

 not round, but oblong, like hay-stacks. They have flat summits, 

 and smooth sloping sides, corresponding with the fronts of that range 

 from which they are detached. 



Having mentioned Blakey Topping, it may be proper to notice 

 here some singular rocks, that run along the margin of a deep ravine, 

 about two miles south from that hill. These rocks, some of which 

 are here represented, are denominated 



THE BRIDE STONES. 



These rocks belong to the series above the second shale, and are 

 somewhat analogous to the marly sandstone at the top of Rowlston 

 scar, though they are much more siliceous. They appear in strata of 

 great thickness, of a yellowish white or grey colour; and being of 

 very unequal hardness, the soft parts, which are nearly in the state
