consist of _Peroxide of iron_. Specimens may be seen in the cabinet at Penzance. Dr. Paris has suggested that they resulted from the decomposition of _Pyrites_, forming, in the first instance, a soluble _Sulphate of iron_, but which, by attracting farther oxygen, deposited its base in the form here discovered. At a little distance southward of Cape Cornwall, is a high rocky promontory called CARAGLOSE HEAD, from which the traveller may command one of the most interesting views in this part of Cornwall. On the north are Cape Cornwall, and the romantic machinery of _Little_ _Bounds Mine_. Southward and directly under the head, the interesting creek called PORNANVON COVE, with the engine of _Huel St. Just Tin Mine_ near the sea shore. Westward, on a clear day, the Scilly Islands may be distinctly seen. This is a spot seldom visited by strangers, but with the exception of Botallack, it is certainly one of the most striking in the district of Saint Just. At _Pornanvon Cove_, a stratum of sea sand and pebbles may be seen in the cliff, at an elevation of fifteen feet above high water mark! Advancing from the coast into the interior of the country towards Saint Just's _Church-town_, Dr. Berger observed many blocks of _Schorl rock_[64] scattered on this part of the granitic plain, particularly amongst the rubbish of some old tin mines, which are here very numerous, but are now quite deserted. SAINT JUST CHURCH TOWN. Nothing of any interest is to be seen at this place, except a very ancient cross, a sketch of which we shall introduce at the conclusion of the present chapter; and the remains of an ancient Amphitheatre. In this, and similar "_Rounds_," as they are provincially called, the ancient British assembled, in order to witness those athletic sports, for which the Cornish are still remarkable; indeed, at this very day, wrestling matches are held in the amphitheatre at Saint Just, during the holidays of Easter and Whitsuntide.[65] The Antiquary ought not to quit this parish without visiting the "_Botallack Circles_;" when examined separately they do not differ essentially from that at _Bolleit_, or at _Boscawen Un_ before described (p. 81); but they intersect each other and form a confused cluster; "but in this seeming confusion," exclaims Dr. Borlase, "I cannot but think that there was some mystical meaning, or, at least, distinct allotment to particular uses; some of these might be employed for the sacrifice, others allotted to prayer, others to the feasting of the priests, others for the station of those who devoted the victims; and lastly, that these circles intersected each other in so remarkable a manner, as we find them in this monument, might be to intimate that each of these holy rites, though exercised in different circles, were but so many links of one and the same chain, and that there was a constant dependance and connection between sacrifice, prayer, holy feasting, and all the several parts of Druidical worship."
