The height of the "Studio" is about 18 feet. This _atelier_ is a marvel of beauty. There are in it two temples of the most lovely kind. Large masses of splendid stalactites hang from the roof. On the walls are columns profusely decorated with coral and tracery and bosses, and carvings which could be imitated only by the most cunning workmanship. Near the centre is a large stalactitic mass, most graceful in shape, with numerous appendages; and underneath appear several stalagmites. Some of them have been partially destroyed, but one, which touches the enormous mass of stalactites above, remains intact. Near to this is a splendid column, richly embellished. The walls are profusely adorned with elaborate configurations, which are supposed to represent architectural "studies," from which the cave derives its name. Most of the formation is white or light grey; but in some of the recesses there is rich colouring. Each chamber has its own distinctive attractions, and contains many objects which challenge special admiration. Massive grandeur is set off with the most delicate and fragile beauty. Stalagmites are not numerous here, but one about eight feet in height, and two inches in diameter at the base, tapers off gradually towards the roof until it becomes as attenuated as the thin end of a fishing-rod. The stalactitic formation hangs in ponderous grotesquely-shaped concretions, some of which extend from the roof nearly to the floor, and many of the stalactites which decorate the stalactitic formation are perfect in shape and purity. The choicest portions of the Architect's Studio are fenced off with galvanised wire rope on iron standards. THE BONE CAVE.
