The route now taken leads us behind the Giant’s Coffin, through a low and narrow passage which would never have been discovered had not the monster rock fallen. This is styled Dante’s Gateway, from which a rude stairway leads us into the Wooden Bowl Room, so named either from its peculiar shape or because an Indian wooden bowl was found there. To the left is the opening to what has variously been styled Indian Avenue, Blacksnake Avenue, and Welcome Avenue. Really it is a combination of several avenues, running for the distance of eight thousand five hundred feet, as measured by the writer, which have been made passable by the skill and industry of Mr. H. C. Ganter when he was manager of the Cave, and which for this reason is generally called Ganter Avenue. Its inner end is at Serpent Hall, and it gives an exit for any one who may get caught beyond the rivers by a sudden rise of water. Our present path goes through the “Dog-Hole,” down a stairway fancifully called “The Steeps of Time,” leading into the region of pits and domes. We pause a while by Richardson’s Spring, which is a small pool filled by a running stream that has worn for itself a narrow channel in the rock, illustrating what has been done for the entire Cave on a grander scale. Small crustaceans are found in this clear pool, and blind insects abound under the flat rocks near by. Numberless blind crickets leap away from us, and white eyeless spiders, brown beetles, thousand-legged worms, and other abnormal forms of life are found by careful search. Nothing harmful, however, appears, either here or elsewhere. As a rule cave-life is timid. Side-saddle Pit, fifty feet deep, was named from its imagined resemblance to a lady’s saddle. Above it rises Minerva’s Dome, thirty feet high. The spot used to be dangerous, but is now guarded by a stout railing. Once a terrier leaped down the Chasm after a fire-ball flung by a guide. The guide’s wife allowed herself to be lowered by a rope and rescued the poor dog, which did not seem to be seriously hurt by his perilous adventure. Calypso’s Avenue, to the left, leads to the Covered Pit and Scylla and Charybdis, which are rarely visited. Near the entrance to the Labyrinth is a window through which we behold the wonderful and lofty chamber discovered by a former owner of the Cave, Mr. Frank Gorin, in whose honor it is named Gorin’s Dome. Perhaps the earliest account of it was that published by Dr. Davidson. Its height, as measured by myself with the aid of a cluster of small balloons, is one hundred and sixty feet, its width is thirty-five feet and its length sixty feet. Its vertical walls sweep in an S-shaped curve and spring from the river level to the apex of the dome, with projecting bosses of coral and with cascades that awake the echoes as they fall.
