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 same as 

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

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

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



much
