thing that is now carrying us farther and farther toward the eternal central fires.”

I am frank to admit that for myself I was much more concerned with our own immediate future than with any problematic loss which the world might be about to suffer. The world was at least ignorant of its bereavement, while to me it was a real and terrible actuality.

“What can we do?” I asked, hiding my perturbation beneath the mask of a low and level voice.

“We may stop here, and die of asphyxiation when our atmosphere tanks are empty,” replied Perry, “or we may continue on with the slight hope that we may later sufficiently deflect the prospector from the vertical to carry us along the arc of a great circle which must eventually return us to the surface. If we succeed in so doing before we reach the higher internal temperature we may even yet survive. There would seem to me to be about one chance in several million that we shall succeed⁠—otherwise we shall die more quickly but no more surely than as though we sat supinely waiting for the torture of a slow and horrible death.”

I glanced at the thermometer. It registered 110 degrees. While we were talking the mighty iron mole had bored its way over a mile into the rock of the earth’s crust.

“Let us continue on, then,” I replied. “It should soon be over at this rate. You never intimated that the speed of this thing would be so high, Perry. Didn’t you know it?”

“No,” he answered. “I could not figure the speed exactly, for I had no instrument for measuring the mighty power of my generator. I reasoned, however, that we should make about five hundred yards an hour.”

“And we are making seven miles an hour,” I concluded for him, as I sat with my eyes upon the distance meter. “How thick is the Earth’s crust, Perry?” I asked.

“There are almost as many conjectures as to that as there are geologists,” was his answer. “One estimates it thirty miles, because the internal heat, increasing at the rate of about one degree to each sixty to seventy feet depth, would be sufficient to fuse the most refractory substances at that distance beneath the surface. Another finds that the phenomena of precession and nutation require that the earth, if not entirely solid, must at least have a shell not less than eight hundred to a thousand miles in thickness. So there you are. You may take your choice.”

“And if it should prove solid?” I asked.

“It will be all the same to us in the end, David,” replied Perry. “At the best our fuel will suffice to carry us but three or four days, while our atmosphere cannot last to exceed three. Neither, then, is sufficient to bear us in safety through eight thousand miles of rock to the antipodes.”

“If the crust is of sufficient thickness we shall come to a final stop between six and seven hundred miles beneath the earth’s surface; but during the last hundred and fifty miles of our journey we shall be corpses. Am I correct?” I asked.

“Quite correct, David. Are you frightened?”

“I do not know. It all has come so suddenly that I scarce believe that either of us realizes the real terrors of our position. I feel that I should be reduced to panic; but yet I am not. I imagine that the shock has been so great as to partially stun our sensibilities.”

Again I turned to the thermometer. The mercury was rising with less rapidity. It was now but 140 degrees, although we had penetrated to a depth of nearly four miles. I told Perry, and he smiled.

“We have shattered one theory at least,” was his only comment, and then he returned to his self-assumed occupation of fluently cursing the steering wheel. I once heard a pirate swear, but his best efforts would have seemed like those of a tyro alongside of Perry’s masterful and scientific imprecations.

Once more I tried my hand at the wheel, but I might as well have essayed to swing the earth itself. At my suggestion Perry stopped the generator, and as we came to rest I again threw all my strength into a supreme effort to move the thing even a hair’s breadth⁠—but the results were as barren as when we had been traveling at top speed.

I shook my head sadly, and motioned to the starting lever. Perry pulled it toward him, and once again we were plunging downward toward eternity at the rate of seven miles an hour. I sat with my eyes glued to the thermometer and the distance meter. The mercury was rising very slowly now, though even at 145 degrees it was almost unbearable within the narrow confines of our metal prison.

About noon, or twelve hours after our start upon this unfortunate journey, we had bored to a depth of eighty-four miles, at which point the mercury registered 153 degrees F.

Perry was becoming more hopeful, although upon what meager food he sustained his optimism I could not conjecture. From cursing he had turned to singing⁠—I felt that the strain had at last affected his mind. For several hours we had not spoken except as he asked me for the readings of the instruments from time to time, and I announced them. My thoughts were filled with vain regrets. I recalled numerous acts of my past life which I should have been glad to have had a few more years to live down. There was the affair in the Latin Commons at Andover when Calhoun and I had put gunpowder in the stove⁠—and nearly killed one of the masters. And then⁠—but what was the use, I was about to die and atone for all these things and several more. Already the heat was sufficient to give me a foretaste of the hereafter. A few more degrees and I felt that I should lose consciousness.

“What are the readings now, David?” Perry’s voice broke in upon my somber
