of _Titanium_, are to be found also in this interesting spot. CAPE CORNWALL is the next object of interest after Botallack. This point of land stretches out to the west, at an elevation of two hundred and thirty feet, and forms the northern boundary of _Whitsand Bay_ (p. 88). It is entirely composed of a slaty rock, traversed by numerous veins of _Actinolite_. To the geologist this spot will be interesting, since on the shore beneath, a junction may be observed between the _Granite_ of the Land's End, and the slate of this promontory.[63] These formations are separated by a large vein of _metalliferous quartz_, which forms the _lode_ of the mine in the neighbourhood, called "_Little Bounds_," and whose engine suspended in the cliff above, constitutes a very striking feature in the scenery. This vein, besides _Oxide of Tin_, for which it is worked, contains _Native Copper_, different _Oxides of Iron_, _Red Jasper_, _Quartz_ of a bright brownish red colour, and _Scaly red Iron_ _ore_, sometimes investing Quartz, and occasionally in small masses consisting of red cohering scales, which are unctuous to the touch. Mr. Carne states, that in this mine three distinct lodes, distant from each other, have been worked under the sea; two of them being in granite, the third in slate. Here also, at two parts of the _lode_, known by the name of "_Save-all's lode_," probably, as the name would seem to imply, in consequence of the avarice of the miner, a communication has been made between the sea and the mine; one of them is at about high water mark at spring tides; the other is covered by the sea at every tide, except at very low neaps; great and constant attention is therefore necessary for the security of this latter breach. At first the opening was stopped by a piece of wood covered with turf; but as this defence was not found to be sufficiently secure, a thick platform caulked like the deck of a ship, was ultimately placed upon it, and which renders it nearly water proof. The breaking of the waves is heard in all the levels of the mine, and in the part directly beneath the pebbly beach, the rolling of the stones in boisterous weather produces a most terrific effect. In the drift at the forty fathom level, which is carried a considerable way under the sea, Mr. Chenhalls, the intelligent agent of the mine, had formerly observed a successive formation of _Stalactites_; in consequence of which statement, Dr. John Davy and Mr. Majendie were induced to visit the spot. It had been closed for two years previously, but before it was shut up Mr. Chenhalls had carefully removed all the _Stalactites_ which then existed. Upon examination it was observed that a fresh crop had been produced during the interval just stated; some of which were eighteen inches in length, and above an inch in diameter. The _Stalagmites_ directly underneath them were of still larger dimensions; both however had the same yellowish-brown colour, and were found to
