The _Tournier-platz_ or Place of the Tournament, is a lofty and extensive cavern, the floor of which is formed of very fine sand, and is exceedingly level and firm. The shape of the vault is oval, and the sides have some slight resemblance to an amphitheatre. On Whit-Monday the whole of the grotto is illuminated, and hundreds flock to behold this curious scene, the _Tournier-platz_ being arranged as a ball-room, and in which the visitors dance till a very late hour. From thence we went through long passages and caverns, each of which presents something remarkable. In one, a large pillar rises from the ground, which, on being struck with a stone or stick, gives out a sound resembling the deep and sonorous tone of a tolling bell; and in another, stands a large fluted pillar, to which the guides give the strange name of the _Kanonen-Säule zu Moskau_, or the Pillar of Canons at Moscau. In another part of the cavern we see a vase, on the top of a small pillar, constantly full of water, which falls into it, drop by drop, from the roof; it is perfectly clear, and icy cold. Beyond this font, we came to the _great curtain_, the most striking single stalactite in the whole cavern. The limestone here descends in many a waving and beautiful fold from the roof, from a height of upwards of twenty feet, and projecting about six feet out from the rock. The whole mass is exceedingly thin, and is bordered by a stripe of red. Seen from a distance, when the guides hold their lamps behind it, the effect is highly striking, and the spectator can hardly believe that the transparent curtain before him is formed of hard stone. The red colour in the edge of this mass of limestone, is the only instance of the kind I met with in the grotto, the general colour of the stalactites being either pure white or whitish brown: and they are often covered with a crust of very fine crystals. At some distance beyond the curtain, the cave divides into two branches, one of which ends with a large block of limestone, that bears the name of the _high altar_; the other has been rarely trodden by the foot of a stranger, for my guide said that this was only the second time that he had been there, since the discovery of that part of the cave, by him and another of the men who were with me, six or seven years ago. It extends for a considerable way, till all further progress is stopped by a large pool of water, over which the guides said no one had ever crossed. This pool did not appear to me to be of any very great extent, and I felt persuaded, that with the help of a few long poles, it would have been possible to have passed over the slippery rocks on its sides; we had, however, nothing of the kind with us, and I was obliged to abandon the idea, nor did the guides appear at all inclined to continue our peregrinations, having already penetrated to a greater distance than usual. I carefully examined the water, but in vain, to
