OF THE FAROE ISLANDS. 25& 



ft emits the same intolerable smell ; and produces a very large 

 proportion of ash. At Ballintoy it occurs only in small beds, 

 sometimes in very minute patches, and is used only in burning 

 lime. 



I think it is fair, therefore, to conclude, that this coal pre- 

 sents none of the characters of regular stratification ; and it be- 

 sides, appears to be totally unaccompanied with sandstone, as 

 I find it immediately connected with- trap in some of the spe- 

 cimens I have got. So far as we saw, sandstone does not oc- 

 cur in the country. Landt mentions generally, that it is to 

 be found in the dales of Nordstrom oe. We nowhere, however, 

 saw any vestiges of it ; and from the very low ebb of his geo- 

 logical acquirements, nothing on that subject, unless corrobo- 

 rated by other testimony, can be attended to, as we may judge 

 by the following passages, quoted from Captain Born, as au- 

 thority. " If (says he) a bluish-grey fine-grained sort of stone, 

 " which contains grains of quartz and calcedony, be not gra- 

 " nite or limestone, neither the one or other is to be found in 

 " the islands." Page 140; 



The varieties of trap we met with, were Greenstone, Poi^ 

 phyritic Greenstone, Amygdaloid, Trap-tuff, and Porphyry- 

 slate. Basalt we found only in a few dykes ; we nowhere saw 

 it in beds, or presenting the beautiful articulated columns of 

 StafFa and the Giant's Causeway. The beds composed of 

 these different kinds of trap, have one uniform dip and direc- 

 tion ; stretching from S. S. E. to N. N. W., and so very slight- 

 ly inclined, that it required a considerable portion of the rock 

 to be seen at once, to render the inclination perceptible. 

 When surveyed from the north or south, the beds conse- 

 quently appear horizontal; while on the east and west sides 

 an inclination is observed, dipping almost imperceptibly for- 

 wards the south.
