By means of a wire ladder the excursionist descends still deeper into the bowels of the earth. He then goes farther down by 18 or 20 steps, cut in a clayey substance, to the vestibule of the Music Hall. Some of the stalagmites are stained with clay. They have evidently been used as steadying-posts by visitors who had previously placed their hands on the red earth when working their way down the declivity where the steps are now formed. The other stalagmites away out of reach are white and glistening. The approach to the Music Hall, which was discovered in the summer of 1860, is low. The passage to it is about 35 yards long. The floor is composed entirely of "formation," and at the sides are numerous columns of different colours. The Music Hall itself is about 12 feet in height, and runs out at the end to about two feet. It is called the "Music Hall" because of its very fine acoustic properties. A weak voice raised in song or oratory sounds full and sonorous. This hall encloses a secret which architects of public buildings might covet, and the wonder is how such tonic effects are produced in a chamber which presents so many obstructions to the waves of sound. The floor contains a series of basins, curiously shaped by the water which has been retained in them, until it has escaped by percolation to form stalactites and stalagmites at some lower level. The edges of these shallow reservoirs are sharply defined and gracefully moulded. The formation of the walls is extremely delicate. Some of it is white and some like yellow coral. The roof has been slightly defaced by certain nineteenth century cads. In various places the "mark of the beast," in lampblack, has been produced by holding candles near to the ceiling and moving them about gradually, and the sooty hieroglyphics remain unto this day as an evidence of vanity and folly. The floor, which was once like alabaster, is now soiled by the tramping of feet. But, notwithstanding these defects, the Music Hall is still very beautiful.
