The Cave of Fingal

Sir Joseph Banks, will not be apt to accuse him of being liable to be hurried away by the force of a too ardent imagination; but the sensation which he felt at the view of this magnificent scene was such, that it was impossible to escape a degree of just enthusiasm. "The impatience which every body felt to see the wonders we have heard so largely described, prevented our morning's rest; every one was up and in motion before the break of day, and with the first light arrived at the south-west part of the island, the seat of the most remarkable pillars. We were no sooner arrived at this place, than we were struck with a scene of magnificence which exceeded our expectation, though formed as we thought upon the most sanguine foundations The whole of that end of the island is supported by ranges of natural pillars, mostly above fifty feet high, standing in natural colonnades, according as the bays or points of land formed themselves, upon a firm basis of solid shapeless masses of rock. In a short time we arrived at the mouth of the cave, the most magnificent, I suppose, that has ever been described by travellers. 'The mind can hardly form an idea of any thing more magnificent than such a space, supported on each side by ranges of columns, and roofed by the bottoms of those from which they have been broken, in order to form it, between the angles of which a yellow stalagmitic matter has exuded; this serves to define the angles precisely, and at the same time vary the colour with a great deal of elegance, and, to render it still more agreeable, the whole is lighted from without; so that the farthest extremity is very plainly seen from the outside, and the air within, being agitated by the flux and reflux of the tides, is perfectly dry and wholesome, entirely free from the vapours with which natural caverns in general abound." The following description of the same place by Mr. Troil, s also worthy of our notice :- "How splendid (says this prelate) do the porticos of the ancients appear in our eyes, from the ostentatious magnificence of the descriptions we have received of them! and with what admiration are we seized, on seeing even the colonnades of our modern edifices! but when we behold the cave of Fingal, formed by nature in the isle of Staffa, it is no longer possible to make a comparison, and we are forced to acknowledge that this piece of architecture, executed by nature, far surpasses that of the Louvre, that of St. Peter at Rome, and even what remains of Palmira and Pestum, and all that the genius, the taste, and the luxury of the Greeks, were ever capable of inventing."-Letters on Iceland.

Such also was the impression made by the cave of Fingal, on Sir Joseph Banks, and on the Bishop of Linckœping.- " I have seen many ancient volcanoes, and have given de scriptions of several superb basaltic causeways and delightful caverns in the midst of lavas; but I have never found any thing which comes near this, or can bear any comparison with it, either for the admirable regularity of the columns, the height of the arch, the situation, the forms, the elegance of this production of nature, or for its resemblance to the masterpieces of art, though this had no share in its construction. It is therefore not at all surprising that tradition should have made it the abode of a hero. "This amazing monument of nature is thirty-five feet wide at the entrance, fifty-six feet high, and a hundred and forty feet long. "The upright columns which compose the frontispiece, are of the most perfect regularity. Their height, to the beginning of the curvature, is forty-five feet. "The arch is composed of two unequal segments of a circle, which form a sort of natural pediment. "The mass which crowns, or rather which forms the roof, is twenty feet thick in the lowest part. It consists of small prisms, more or less regular, inclining in all directions, closely united and cemented underneath, and in the joints, with a yellowish white calcareous matter, and some zeolitic infiltrations, which give this fine ceiling the appearance of mozaic work. "The sea reaches to the very extremity of the cave. It is fifteen feet deep at the mouth; and its waves, incessantly agitated, beat with great noise against the bottom and walls of the cavern, and every where break into foam. The light also penetrates through its whole length, diminishing gradually inwards, and exhibiting the most wonderful varieties of colour. "The right side of the entrance presents, on its exterior part, a vast amphitheatre, formed of different ranges of large truncated prisms, the top of which may be easily walked on. Several of these prisms are jointed, that is, concave on the one side, and convex on the other; and some of them are divided by simple transverse intersections. "These prisms, consisting of a very durable and pure black basaltes, are from one to three feet in diameter. Their forms are triangular, tetrapedral, pentagonal, and hexagonal; and some of them have seven or eight sides. I saw several large prisms, on the truncatures of which are distinctly traced the outlines of a number of smaller prisms; that is, these prisms are formed of a basaltes, which has a tendency to subdivide itself likewise into prisms. I had before observed the same phenomenon in the basaltic prisms of Vivarais. "The cave can be entered only by proceeding along the platform on the right side, which I have mentioned above. But the way grows very narrow and difficult as it advances; for this sort of interior gallery, raised about fifteen feet above the level of the sea, is formed entirely of truncated perpendicular prisms of a greater or less height, between which considerable address is necessary to choose one's steps, the passages being so strait and so slippery, owing to the droppings from the roof, that I took the very prudent resolution, suggested by our two guides, to proceed barefooted, and take advantage of their assistance, especially in a particular place, where I had room only to plant one foot, whilst I clung with my right hand to a large prism to support myself, and held the hand of one of the guides by the other. This difficult operation took place at the darkest part of the cave; and one half of the body was at the time suspended over an abyss, where the sea dashed itself into a cloud of foam. "I was desirous of penetrating to the farthest extremity, and I accomplished my purpose, though not without considerable difficulty and danger. I more than once found my attention distracted from the observations which I was happy to have an opportunity of making, to the thought of how I should get back again. "As I drew near to the bottom of the cave, the bold balcony, on which I walked, expanded into a large sloping space, composed of thousands of broken vertical columns. The bottom was bounded by a compact range of pillars of an unequal height, and resembling the front of an organ."

It is worthy of remark, that at the time when Mr. Troil visited the cave, the sea, by one of those uncommon chances which do not happen once in ten years, was so calm, that it permitted him to enter with a boat. "At the very bottom of the cave, (says he,) and a little above the surface of the water, there is a kind of small cave, which sends forth a very agreeable noise every time that the water rushes into it." - Letters on Iceland. "As the sea was far from being completely still when I visited it, I heard a noise of a very different nature every time that the waves, in a rapid succession, broke against its bottom.

This sound resembled that which is produced by striking a large hard body with great weight and force against another hard body in a subterraneous cavity. The shock was so violent, that it was heard at some distance, and the whole cavern seemed to shake with it. Being close to the place whence the sound issued, and where the water is not so deep, upon the retreat of the wave, I endeavoured to discover the cause of this terrible collision. I soon observed, that, a little below the basis which supported the organ-fronted colonnade, there was an aperture which formed the outlet of a hollow, or perhaps a small cave. It was impossible to penetrate into this cavity; but it may be presumed that the tremendous noise was occasioned by a broken rock, driven by the violent impetuosity of the surge against its sides. By the boiling motion of the water, however, in the same place, it is evident that there are several other small passages, through which it issues, after rushing into the principal aperture in a mass. It is therefore not impossible, when the sea is not sufficiently agitated to put the imprisoned rock in motion, that the air, strongly compressed by the weight of the water, which is in incessant fluctuation, should, on rushing out by the small lateral passages, produce a particularly strange sound. It might then be truly regarded as an organ created by the hand of nature; and this circumstance would fully explain why the ancient and real name of this cave, in the Erse language, is, The Melodious Cave."

Sir Joseph Banks, in the description which he has given us of the cave of Staffa, says, that "between the angles a yellow stalagmitic matter has exuded, which seemed to define the angles precisely." That is true; but the learned naturalist has not told us the nature of this yellowish matter. Mr. Troil mentions it also: he says, that the "colour of the columns is a dark gray, but that the joints are filled with a quartzose stalactites, which distinctly marks the separation of the columns, and which, by the variety of its tints, has the most agreeable effect on the eye. On breaking off several pieces of it, which it is not very easy to do, owing to the height of the vault, I found that it was nothing but a calcareous matter, coloured by the decomposition of the iron of the lava, and intermixed with a little argillaceous earth. This stalactites has also very little adhesion, and is, in general, of an earthy nature. In several of the prisms I found some globules of zeolites, but in very small quantity. I also broke off from between two prisms, which were so apart as to admit of introducing my hand, an incrustation in which the white and transparent zeolites was formed into very perfect small cubical crystals, several of which were coloured red by the ferruginous lime arising from the decomposition of the lava. But I must repeat, that zeolites is very rare in this cave, and having myself broken off all the specimens that I was able to see, I doubt whether those who may visit the place after me wil. find any quantity of it."
