My dear Sir, Wallington^ July 22. 1822. 



aN compliance with your request, I send you a few notes of 

 some of the principal geological facts I observed in Faroe, 

 which may serve as a supplement to Sir George Mackenzie's 

 and Mr Allan's accounts of these islands, which, as far as 

 they extend, I found perfectly correct. 



The Coal in Suderoe, which was not visited by them, is si- 

 tuated between two thick beds of hard clay, resembling the 

 Clunch-clay of this country ; to which succeed beds of trap. In 

 some parts, pieces of petrified wood are very abundant in the 

 superincumbent clay, and also nodules of ironstone ; and in 

 the coal, pieces of wood resembling charcoal. The coal has the 

 same degree of inclination as the other beds, dipping towards 

 the south-east, at an angle of about 4° or 5° ; being the saine as 

 the dip in the other islands, excepting in part of Myggenaeais, 

 where it is miich greater, being near 45°. The thickness of 

 the coal varies from a few inches to 5 or 6 feet, and in quality 



much
