I had not spoken very loudly, but the words seemed to reverberate in my mouth, as if to testify to the correctness of my explanation.
"Yes," said Edmund, taking pains to moderate his voice, "you've hit it, it's the atmosphere. I had calculated on an effect of the kind, but the reality exceeds all that I had anticipated. Spectroscopic analysis as well as telescopic appearances demonstrated long ago that the atmosphere of Venus was extraordinarily extensive and dense, from which fact I inferred that we should encounter some wonderful acoustic phenomena here, and this was in my mind when, on stepping out of the car, I addressed you in a whisper. The reaction even of the whisper on my organs of speech told me that I was right, and showed me what to expect if the full power of the voice were used. When we caught sight of the creature at the top of the pit I had no desire to shoot him, and I saw that he was too powerful to be captured alive. In a second I had decided what to do. It ran through my mind that, in a world where the density, and probably something also in the peculiar constitution of the air, had the effect of vastly magnifying sound, the phonetic and acoustic organs of the inhabitants would be modified, and that the sounds uttered by them would be much fainter than those that we are accustomed to hear from living creatures on the earth. That being so, I argued that a very great and heavy sound coming from a strange animal would produce in the creature before us a paralyzing terror. You have seen that it did so. I expect that this will give us an immense advantage to begin with. We have already inspired so great a fear that I believe that we can now safely follow the creature into its habitation, and encounter without danger any of its congeners that may be there. Nevertheless, I shall not ask you to run any risks, and I will alone descend into the pit."
"If you do, may I be hanged for sheep stealing!"
You will guess at once that it was Jack who had spoken thus.
"No, sir," he continued, "if you go, we all go. Isn't that so, boys?"
In answer to an appeal thus put, neither Henry nor myself could have hung back even if we had had the disposition to do so. But I believe that we all instinctively felt that our place was by Edmund's side, wherever he might choose to go.
"Go ahead, then, Edmund," Jack added, seeing that we consented, "we're with you." And then his enthusiasm taking fire, as usual, he exclaimed: "Hurrah! Columbus forever! We've conquered a hemisphere with a blank shot."
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.
