Mr. Hutton on the Stratiform Basalt. 193 



In Blencairn Burn, the Whin occurs, and here a fine section may be 

 seen of all the beds from the old Red Sandstone to the Great Limestone. 

 North of this its edge does not appear in the escarpment, but it occurs 

 on Melmerby Fell, and has already been extensively indicated in the 

 streams descending eastward from Hartside. 



The whole face of this part of the escarpment is much confused by 

 the sliding down of large masses, which appear to have detached them, 

 selves from the beds above ; thus, in ascending Raven Beck, we appear 

 to meet with the Whin three times, although there is doubtless but one 

 bed.

 between each mass being about Half a Mile.

SANDSTONE 



In each case the water forms a cascade over it. The stratum is about 

 9 fathoms thick, and has in the midst of it a bed of Slaty Sandstone, 

 18 inches to ( 2 feet thick, and so close is the contact between the Whin 

 and Sandstone that, with care, specimens may be obtained of the two 

 substances adhering together. On Croglin Water the Whin appears, 

 having again a stratum of Slaty Sandstone in the midst of it, 6 feet 

 thick. 



The Whin may be seen in Old Water and New Water, which streams 

 united form the Gelt. It also appears in Tarn-Monath Beck, north of
