A Guide to the Mount's Bay and the Land's End / Comprehending the topography, botany, agriculture, fisheries, antiquities, mining, mineralogy and geology of West Cornwall

by John Ayrton Paris

The islanders are chiefly employed in Ashing, making kelp from the Algæ, which is disposed of to the Bristol merchant for the use of the glass manufacturer, and in pilotage. From a combination, however, of unfortunate circumstances, in addition to the fatal blow given to the smuggling trade, by the activity of the preventive service, the inhabitants were reduced to such extreme distress that it became necessary in the year 1819 to appeal to the generosity of the public in their behalf; and, notwithstanding the great difficulties of the times, the sum of nine thousand pounds was collected for their relief. In this great work of charity it is but an act of justice to state, that the Society for promoting Christian knowledge, by their purse, as well as by their writings, performed a very essential service. The funds thus obtained were in part appropriated to the relief of the immediate and pressing distress under which they laboured, while the remainder was very judiciously applied towards the promotion of such permanent advantages as might prevent the chance of its recurrence. A Fish-cellar was accordingly provided in the island of Trescow, for the purpose of storing and curing Ash; boats adapted for the Mackarel and Pilchard Fisheries were purchased, and others were repaired; nets and various kinds of tackling were also at the same time liberally supplied. By such means have the inhabitants of these cheerless rocks been enabled to avail themselves of some of the resources which Providence has placed within their reach, and their families have been thus enabled to exist without the dread of absolute starvation.[43] Much, however, still remains for philanthropic exertion, and should this humble volume fall into the hands of those, who are enabled by the superior gifts of fortune to contribute to the wants of their unhappy brethren, we may perhaps serve their cause by stating that any donation, however small, will be received by Henry Boase, Esq. at the Penzance Bank. The greatest benefit would arise from the extension of their fisheries, for in consequence of the peculiar situation and convenience of these islands, the Cod and Ling fisheries might be carried to almost any extent; and, while boats in any part even of the Mount's Bay, would be weather-bound with the wind W.S.W. to S., they can proceed from Scilly into the channel, without the least difficulty. The Scillonians, however, have as yet been unable to avail themselves of the advantages of their locality; the want of proper boats prevents their proceeding in the pursuit of their occupation, farther than four or five leagues from the land.

During the summer months various species of fish are caught with hook and line; among the smaller kind, which are salted by the Scillonians for their winter consumption, are "Bass, Wrass, Chad, Scad, Brit, Barne, Cuddle, Whistlers," &c. all of which are included by the islanders under the general appellation of "Rock-fish."

There is a very curious fact noticed here with respect to the Woodcock. These birds generally arrive in Scilly before they are observed in any part of England; more frequently with a north-east,[44] though sometimes with a north-west wind, and are often so exhausted as to be caught in great numbers by the inhabitants, especially near the light-house, the splendour of whose light appears to attract them, and striking against its lantern they not unfrequently fall lifeless in the gallery. It is for the naturalist to consider from whence they migrate.

The Climate of these islands is both milder and more equable than that of Cornwall, but this advantage is counterbalanced by the frequent occurrence of the most sudden and violent storms. By those who have kept journals it has been found that not more than six days of perfect calm occur in the course of a year, and that the wind blows from between S.W. and N.W. for more than half of that period.

With respect to Geology, these islands will afford but little variety; with the exception of some beds of Porphyry at Saint Mary's, and some beds of Chlorite, containing Pyrites, in the same island, they consist entirely of Granite, and are doubtless a continuation of the Devonian range, although the rock assumes an appearance less porphyritic; it contains, however, veins of red Granite. At the Lizard Point in the island of Trescow, a variety of granite occurs, in which the felspar is of a remarkably pure white, and might, we should conceive, be advantageously employed in the manufacture of Porcelain. In some chasms of this rock, and in the centre of large masses, the Mica is of a silvery hue, and occurs crystallized in its primitive form. In the same island is a remarkable cavern, in the centre of which is a pool of fresh water. The porphyritic beds in Saint Mary's are interesting on account of the distinct appearance of stratification which they display, and Mr. Majendie thinks that an undoubted instance of stratified granite is to be seen near the same spot. The Granite of Scilly is very liable to decomposition; whence has arisen all that fancied statuary of the Druids, of which we have spoken in another place. The Islands are undoubtedly undergoing a gradual diminution. At no great distance of time Saint Mary's will probably be divided by the sea, and a channel formed through the low land between the New-town and the south-east side of the garrison. This might perhaps be prevented by throwing down masses of granite from a neighbouring hill, so as to form a barrier against the sea. The object may be worthy of attention, as the sea in winter, with a high tide, has been known to pass over this land, and the effect of its forcing a channel there would be to divide the garrison from the rest of the island. If the Geologist proceeds to a spot behind the quay, and between the front of the garrison-hill and that island, he will be gratified by the discovery of a process the very converse of that which we have been just describing. In these places the granitic sand is becoming indurated by the slow infiltration of water holding iron in solution, and which appears to be derived from the decomposing hills above it. Some fine specimens of this "regenerated" granite have been placed in the Geological Society's cabinet at Penzance.

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 lie several miles south-east 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 Shorl; 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.
