The cliff which bounds this extremity is rather abrupt than elevated, not being more than sixty feet above the level of the sea. It is composed entirely of granite, the forms of which present a very extraordinary appearance, assuming in some places the resemblance of shafts that had been regularly cut with the chisel; in others, regular equidistant fissures divide the rock into horizontal masses, and give it the character of basaltic columns; in other places, again, the impetuous waves of the ocean have opened, for their retreat, gigantic arches, through which the angry billows roll and bellow with tremendous fury.

Several of these rocks from their grotesque forms have acquired whimsical appellations, as that of the Armed Knight, the Irish Lady, etc. An inclining rock on the side of a craggy headland, south of the Land’s End, has obtained the name of Dr. Johnson’s Head, and visitors after having heard the appellation seldom fail to acknowledge that it bears some resemblance to the physiognomy of that extraordinary man.

On the north, this rocky scene is terminated by a promontory 229 feet above the level of the sea, called Cape Cornwall, between which and the Land’s End, the coast retires, and forms Whitesand Bay; a name which it derives from the peculiar whiteness of the sand, and amongst which the naturalist will find several rare microscopic shells. There are, besides, some historical recollections which invest this spot with interest. It was in this bay that Stephen landed on his first arrival in England; as did King John, on his return from Ireland; and Perkin Warbeck, in the prosecution of those claims to the Crown to which some late writers have been disposed to consider that he was entitled, as the real son of Edward the Fourth. In the rocks near the southern termination of Whitesand Bay may be seen the junction of the granite and slate; large veins of the former may also be observed to traverse the latter in all directions.

We now return to the Land’s End,—from which we should proceed to visit a promontory called “Castle Treryn,” where is situated the celebrated “Logan Stone.” If we pursue our route along the cliffs, it will be found to be several miles southeast of the Land’s End, although by taking the direct and usual road across the country, it is not more than two miles distant; but the geologist must walk, or ride along the coast on horseback, and we can assure him that he will be amply recompensed for his trouble.

From the Cape on which the signal station is situated, the rock scenery is particularly magnificent, exhibiting an admirable specimen of the manner, and forms, into which granite disintegrates. About forty yards from this Cape is the promontory called Tol-Pedn-Penwith, which in the Cornish language signifies the holed headland in Penwith. The name is derived from a singular chasm, known by the appellation of the Funnel Rock; it is a vast perpendicular excavation in the granite, resembling in figure an inverted cone, and has been evidently produced by the gradual decomposition of one of those vertical veins with which this part of the coast is so frequently intersected. By a circuitous route you may descend to the bottom of the cavern, into which the sea flows at high water. Here the Cornish chough (Corvus Graculus) has built its nest for several years, a bird which is very common about the rocky parts of this coast, and may be distinguished by its red legs and bill, and the violaceous blackness of its feathers. This promontory forms the western extremity of the Mount’s Bay. The antiquary will discover in this spot, the vestiges of one of the ancient “Cliff Castles,” which were little else than stone walls, stretching across necks of land from cliff to cliff. The only geological phenomenon worthy of particular notice is a large and beautiful contemporaneous vein of red granite containing schorl; is one foot in width, and may be seen for about forty feet in length.

Continuing our route around the coast we at length arrive at Castle Treryn. Its name is derived from the supposition of its having been the site of an ancient British fortress, of which there are still some obscure traces, although the wild and rugged appearance of the rocks indicate nothing like art.

ROCKING STONES, LAND’S END, CORNWALL.

The foundation of the whole is a stupendous group of granite rocks, which rise in pyramidal clusters to a prodigious altitude, and overhang the sea. On one of those pyramids is situated the celebrated “Logan Stone,” which is an immense block of granite weighing about sixty tons. The surface in contact with the under rock is of very small extent, and the whole mass is so nicely balanced, that, notwithstanding its magnitude, the strength of a single man applied to its under edge is sufficient to change its centre of gravity, and though at first in a degree scarcely perceptible, yet the repetition of such impulses, at each return of the stone, produces at length a very sensible oscillation! As soon as the astonishment which this phenomenon excites has in some measure subsided, the stranger anxiously inquires how, and whence the stone originated—was it elevated by human means, or was it produced by the agency of natural causes? Those who are in the habit of viewing mountain masses with geological eyes, will readily discover that the only chisel ever employed has been the tooth of time—the only artist engaged, the elements. Granite usually disintegrates into rhomboidal and tabular masses, which by the farther operation of air and moisture gradually lose their solid angles, and approach the spheroidal form. De Luc observed, in the giant mountains of Silesia, spheroids of this description so piled upon each other as to resemble Dutch cheeses; and appearances, no less illustrative of the phenomenon, may be seen from the signal station to which we have just alluded. The fact of the upper part of the cliff being more exposed to atmospheric agency, than the parts beneath, will sufficiently explain why these rounded masses so frequently rest on blocks which still preserve the tabular form; and since such spheroidal blocks must obviously rest in that position in which their lesser axes are perpendicular to the horizon, it is equally evident that whenever an adequate force is applied they must vibrate on their point of support.

Although we are thus led to deny the Druidical origin of this stone, for which so many zealous antiquaries have contended, still we by no means intend to deny that the Druids employed it as an engine of superstition; it is indeed very probable that, having observed so uncommon a property, they dexterously contrived to make it answer the purposes of an ordeal, and by regarding it as the touchstone of truth, acquitted or condemned the accused by its motions. Mason poetically alludes to this supposed property in the following lines:
