The archways and ceilings were everywhere hung with down-growing crystals, like inverted groves of leafless saplings, some of them large, others delicately attenuated, each tipped with a single drop of water, like the terminal bud of a pine-tree.

The only appreciable sounds were the dripping and tinkling of water failing into pools or faintly plashing on the crystal floors.
In some places the crystal decorations are arranged in graceful flowing folds deeply plicated like stiff silken drapery.

In others straight lines of the ordinary stalactite forms are combined with reference to size and tone in a regularly graduated system like the strings of a harp with musical tones corresponding thereto; and on these stone harps we played by striking the crystal strings with a stick.

The delicious liquid tones they gave forth seemed perfectly divine as they sweetly whispered and wavered through the majestic halls and died away in faintest cadence,--the music of fairy-land.

Here we lingered and reveled, rejoicing to find so much music in stony silence, so much splendor in darkness, so many mansions in the depths of the mountains, buildings ever in process of construction, yet ever finished, developing from perfection to perfection, profusion without overabundance; every particle visible or invisible in glorious motion, marching to the music of the spheres in a region regarded as the abode of eternal stillness and death.
The outer chambers of mountain caves are frequently selected as homes by wild beasts.
