IN StTDEEOE, FAROE ISLANDS. 623 



No. 2. 68 metres above sea-level, — This is a small opening made in 

 tlie mountain-side and exposes to view a seam of coal 0*34 metre 

 thick ; but the thickness of the coal-bearing strata is not proved. 



No. 3. 120 metres above sea-level. — This is similar to No. 2. About 

 3 metres in depth of ground has been opened out, and 5 small seams 

 of coal, from 0*07 metre to 0-12 metre thick, found ; probably the 

 thicker seams are either above or below. 



No. 4. 212 metres above sea-level. — At this point a small heading, 

 or adit, has been driven in the coal-seam, with the following 

 section : — 



metre. 



Coal 0-37 



Argillaceous shale with small coal-seams 041 



Coal 0-21 



Soft clay 0-17 



No. 5. 239 metres above sea-level. — This is the almost perpen- 

 dicular side of the mountain next the Atlantic. A heading has been 

 driven in the coal-seams about 8 metres in length, and at the end of 

 this heading I took the following section : — 



metre. 



Coal (bright hard coal) 0-80 



Argillaceous shale 0-62 



Coal 0-19 



Argillaceous shale 0'20 



Coal 0-34: 



At a vertical depth of 13 metres below this heading two seams of 

 coal were found of 0*44 metre and 0"15 metre thick respectively, with 

 0-60 m. of argillaceous shale between them. It is my opinion that 

 the section given above, represents the seams worked in the Qvalboe 

 mines, and that these lower seams probably lie under the coal now 

 being worked in the Qvalboe valley. 



No. 6. About 220 metres above sea-level.— This is inaccessible, it 

 being a perpendicular cliif, and can only be reached by a rope from 

 the rocks above ; but it can, in calm weather, be approached on foot 

 within 50 metres, and then is seen the full thickness of the coal- 

 bearing strata, which I judged to be about 15 metres, with hundreds 

 of metres of trap rock above, and a similar rock below to the sea- 

 level. 



No. 7. 8 metres above sea-level. — Two headings, or adits, have been 

 driven in the coal-bearing strata at this point ; but very little coal 

 being found, it was abandoned. There is, however, one curious phe- 

 nomenon noticed at this place, viz. a small seam of coal 0'04 metre 

 thick, and directly upon the top rests trap-rock without any other rock 

 intervening. In places the surface of the coal next the trap-rock 

 appears burnt, as if an igneous rock had, whilst hot, flowed over it. 

 I noticed this in more than one place, and found similar pieces near 

 1^0. 4 in 1873. 



No. 8. 249 metres above sea-level. — This is on the southern side of 

 the Trangisvaag valley, and consists of a heading driven in the coal- 

 seam for about 30 metres, at the end of which a good section is 

 exposed to view.
