XI. On the Geognosy and Mineralogy of Scotland

Published online by Cambridge University Press:  14 March 2018

Extract

Every writer has his moods. It may be thought that the present writer was cynical and severe in his remarks on the geognostic features of Caithness. With a view to remove any such impression, Dr. Maculloch's opinion of that country is quoted ; specially in order that it may be used as a foil to what has to be said concerning the geognosy of Sutherland.

Hear then Macculloch. “On entering into Caithness all the pleasures of travelling are gone and past, for an uglier country from one end to the other would not easily be found. In the usual sweeping manner of those who love to generalise, like Humboldt, it is level, or, at least, not hilly, without trees, without enclosures, as black and as flat as Bagshot Heath ; as flat as a pancake ! Nature has provided no monuments, and has refused to be its poet.

page 146 note * This feature will be seen in the sketch of “The flank of Suilven,” and also in the foreground of one—the upper—of the sketches of “The hills which look as if they had tumbled out of the clouds.” The foreground of the lower, with its gently sweeping curves, oonsists of the “Upper gneiss.”

page 147 note * At Loch Garbat More the scenery is very grand,—the angling is however poor. Loch Garbat Beg is somewhat tame, scenically, but the angling is super-excellent. In the Visitors’ Book at the Inn of Rhiconich there has been written.

Loch Garbat More, I beg you see.

Artist.

Lorch Garbat Beg is more to me.

Angler.

Those who are “Heelan” enough to be able to translate more and beg will see the point.

page 149 note * Our fellow member, Mr. Colin Phillip, tells me that, from the altitude which he attained upon its western slopes, he was able to see that the summit of The Maiden,—a hill which lies north of Slicoh, consisted apparently of the “old gneiss,” and was either that rock or the “igneous rock” of the great fault,—(afterwards to be noticed).

If this be so,—and I have great confidence in his experienced eye—then, as the Maiden is about the height of Slioch, and certainly over 3200 feet, it must be the highest peak of the old gneiss. Cleesham, in Harris is, by the author's measurement, 2,785 feet.

page 150 note * Since the above was in print, I have read a report of Professor Ramsay's address to The British Association, on the occasion of its Meeting at Swansea. In this he says, —“I received a letter from Professor Geikie, in which he informed me that he had discovered mammillated moutonnée surfaces of Laureutian rocks, passing underneath the Cambrian Sandstones of the north-west of Scotland, at intervls, all the way from Cape Wrath to Loch Torridon, a distance of about 90 miles.”

page 152 note * The Minch is in the direct line of the Antrim, —Shiant, —Farŏe, volcanic outburst. It may be a fall-in.

page 153 note * “The other side of Chaos,” was the expression of one upon his return, solemnised by an early morn's first inspection of them.

page 162 note * I cannot speak as to the Maiden, never having ascended it.

page 163 note * There probably was a fault some miles to the west, —the Lewisian Laud being left, throughout the deposition of the quartzite, above water. Was it the fault which cuts-off Handa? It would be an easy explanation of the reversed dip of the Torridon rock—usually S.E. in Sutherland, N.W. in Torridon—to hold, than an axis of elevation ran up the country along the line of reversal. It would be most satisfactory if this could be found ; unfortunately, although that line is in many places admirably exposed for investigation, there is evidence along it of neither folding, crushing, nor of fault. Of course, in accordance with the requirements and dogmas of fire-side geology, there must be one or other.

page 172 note * Beg pardon, Sir ; chemists and other naturalists only maintain that beauty will be appreciated all the more if its causes are understood. P.D.

Right, my boy ;—and so the primal source of these “causes” more nearly approached.
