“Here we left the broad main cave in which we had thus far been traveling, and which stretched on indefinitely before us, and turned off into a narrow, circuitous, irregular avenue, and wandered indefinitely. Clambering over rocks, going down precipitous steeps, passing a great variety of rooms, lofty domes, intricate labyrinths, pits from seventy-five to one hundred and seventy-five feet deep, and a great many other points, all appropriately and often very significantly named, we at length came to Gorin’s Dome, so called from the name of its discoverer, by far the most imposing I had yet seen. Coming to the end of a narrow avenue, the guide directed me to look through an opening in the wall, a kind of window, and our lamps revealed hights above and depths below, that seemed interminable! He then kindled one of the lights that I have already described, and placing it upon a board, thrust it through the opening and told me to look, first below and then above. The view was utterly indescribable and almost overpowering. The opening was not more than thirty feet in circumference, and I have already forgotten the hight and depth as given me by the guide. But I felt for hours and still feel the tremblings of those emotions that thrilled through my whole frame as I peered into those abysmal depths, and looked up into those giddy hights. None but Jehovah could build such a dome. “I can not undertake to give the details of our route from avenue to avenue, nor mention the various points of interest that we passed. We were at length in a vast open space; the guide took our lamps, and going a short distance from us, told us to look up, and we at once discovered that we were in the far-famed Star Chamber. The cave here is some twenty or thirty yards wide, and about sixty or seventy feet high, and in a dim light the arch above presents the appearance of the sky in a very starry night. On looking up you see innumerable stars, and as you gaze for a long time the sky seems to be very distant, the stars increase in number, and it seems quite as if you were really looking through an opening in the cave into the heavens. Our guide Alfred was with Professor Silliman when he examined this arch by the aid of a Drummond light, to discover the cause of this appearance, and found that it was crystals embedded in the wall. After we had satisfied ourselves with viewing this artificial sky, Alfred took all our lamps and going into a cave below us, by the shadows from his lamps gave us a representation of clouds passing over the sky, obscuring the stars, thunder-clouds rolling over and the stars appearing again, and other interesting illusions. After this he went still deeper in the cave below us, leaving us in the most pitchy darkness. We were so deep in the bowels of the earth that the loudest thunder has never been heard there, and the silence and darkness were awfully impressive. Suddenly we saw in the direction in
