Red Sandstone. 



1. Red Sandstone. This deposite forms seve* 

 ral tracts of country in the middle district of 

 Scotland ; and of these, the most extensive is that 

 to which we shall at present confine our atten- 

 tion* It stretches from Stonehaven in Kincardine- 

 shire, to the west side of the Island of Arran, 

 in the Frith of Clyde ; and it varies in breadth 

 from a few fathoms to many miles. In some places, 

 as in Kincardineshire, it forms extensive flats or 

 plains, whilst in others, it rises into hills, or ranges 

 of hills ; and of these latter, the most extensive 

 and highest are the Ochil and Seadly ranges, some 

 of whose summits are 2000 feet above the level 

 of the sea. On the coasts of Kincardineshire and 

 Angusshire, and also on the shores of Arran, it 

 forms striking sea-beat precipices ; or is hollowed 

 into caves of great grandeur and magnificence.
