head, which it is impossible to describe. The streams unite below us, and after tumbling a little way among rocks, they are lost in another cavern, called the grotto of the Syren; but all these names are modern fancies, which merely serve to distinguish the different places. You may cross the stream over the last-mentioned grotto, and descending on the opposite side, enter into its mouth and look down the abyss. All these caverns are very much inclined in their direction, and the water falls, rather than flows through them. The inequality of the ground renders it necessary to make a long circuit in order to reach the lower part of the river; and in so doing you may observe, or fancy you observe, some remains of the ancient bridge, which stood nearly where is now the grotto of the Syren, deeply encrusted in this universal deposit. Looking upwards, you see the temple, the city, the rocks, the falls, combined in the most magical manner. It is a scene however, which it is difficult to characterize. It might be called sublime, if the objects of beauty were not so numerous; and if its sublimity and beauty were less impressive, you would pronounce it the most picturesque view that was ever beheld. Some parts of the rocks are covered with aloes; their tall flower-stalks rising above the olive groves; and some with the Indian fig; both of which give a singularity to the scene which renders it more attractive. The river after its second disappearance, bubbles up with great force at the foot of a high rock, in a most delightful sequestered spot. It is said to deposit about one inch and a half per annum of its solid tartar; if so it ought to be continually elevating its bed, yet there is a hole thirty or forty feet above its present level, through which it has evidently run, and still higher, another passage; indeed, as I said before, the whole rock to the very summit, is of the same nature, and its formation has forced the water through partial channels at different elevations, instead of always keeping the lowest part of the valley. This deposit only takes place where the water is disturbed, and above the town there is none of it.
