And so we began our descent into the mysterious pit. The strange light that came from it, and formed a shaft in the dense atmosphere above like sunlight in a haymow, was accompanied by a considerable degree of heat, which was very grateful to our lungs after the frigid plunge that we had taken from the comfortable car. As we descended, the temperature continually rose until we were glad to throw off our Arctic togs, and leave them on a shelf of rock to await our return. But, fortunately, we did not forget to take the pistols from the pockets before leaving the garments. I am very uncertain what would have been the future course of our history if we had neglected this precaution. It was an awful hole for depth. The steps, rudely cut, wound round and round the sides like those in a cathedral tower, but the pit was not perfectly circular. It looked like a natural formation, such as the vertical entrance to a limestone cavern, or the throat of a sleeping volcano. But whatever the nature of the pit might be, I was convinced that the steps were of artificial origin. They were reasonably regular in height and broad enough for two, or even three, persons to go abreast. When we had descended perhaps as much as two hundred feet, we suddenly found ourselves in a broad cavern with a surprisingly level floor. The temperature had been steadily rising all the time, and here it was as warm as in an ordinary living room. The cavern appeared to be about twenty yards broad and eight or ten feet in height, with a flat roof of rock. It was dimly illuminated by a small heap of what seemed to be hard coal, burning in a very roughly constructed brazier, which, as far as looks went, one would have said was constructed of iron. You will imagine our surprise upon seeing these things. The appearance of the gorilla-like beast with the awful eyes had certainly not led us to anticipate the finding in his lair of any such evidences of human intelligence, and we stood fast in our tracks for a minute or two, nobody speaking a word. Then Edmund said: "This is far better than I hoped. I had not thought about caverns, though I ought to have foreseen the probability of something of the kind. It is hard to drive out life as long as a world has solid foundations, and air for breathing. I shall be greatly surprised now if these creatures do not turn out to be at least as intelligent as our African or Australian savages." "But," said I, "the fellow that we saw surely cannot have more intelligence than a beast. There must be some more highly developed creatures living here." "I'm not so sure of that," Edmund responded. "Looks go for nothing in such a case. He had arms and hands, and his brain may be well organized." "If his brain is as big as his eyes," Jack put in, "he ought to be able to give odds to old Solomon and beat him easy. My, but I'd like to see their spectacles--if they ever wear any!"
