An Account of the Logan Rock. 



[The mischievous displacing of this curious rock, noticed in 

 our last, having excited much attention, we have extracted the 

 following account of it from a " Guide to the Mount's Bay and 

 the Land's End, &c. By a Physician." The work is generally 

 attributed to Dr. Paris. — Edit.] 



We now return to the Land's End, — from which we should 

 proceed to visit a promontory called Castle Tieryn, where is 

 situated the celebrated Logan Stone. If we pursue our route 

 along the cliffs, it will be found to lie several miles south-easiof 

 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 disinte- 

 grates. About forty yards from this Cape is the promontory 

 called Tol-Pedn-Penwith, which in the Cornish language signi- 

 fies 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 Gracutus)\ms built its nest for several years y 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 viola- 

 ceous blackness of its feathers. This promontory forms the 

 western extremity of the Mount's Bay. The antiquary will dis- 

 cover 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 contempora- 

 neous 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.
