style="font-size:15px;"> "Gad!" he cried, "it cannot be possible--quick! What does the distance meter read?"That and the speedometer were both on my side of the cabin, and as I turned to take a reading from the former I could see Perry
muttering.
"Ten degrees rise--it cannot be possible!" and then I saw him tug frantically upon the steering wheel.
As I finally found the tiny needle in the dim light I translated Perry's evident excitement, and my heart sank within me. But when I spoke I hid the fear which haunted me. "It will be seven hundred feet, Perry," I said, "by the time you can turn her into the horizontal."
"You'd better lend me a hand then, my boy," he replied, "for I cannot budge her out of the vertical alone. God give that our com-
bined strength may be equal to the task, for else we are lost."
I wormed my way to the old man's side with never a doubt but that the great wheel would yield on the instant to the power of my young and vigorous muscles. Nor was my belief mere vanity, for always had my physique been the envy and despair of my fellows. And for that very reason it had waxed even greater than nature had intended, since my natural pride in my great strength had led me to care for and develop my body and my muscles by every means within my power. What with boxing, football, and baseball, I had been in training since childhood.
And so it was with the utmost confidence that I laid hold of the huge iron rim; but though I threw every ounce of my strength into it, my best effort was as unavailing as Perry's had been--the thing would not budge--the grim, insensate, horrible thing that was holding us upon the straight road to death!
At length I gave up the useless struggle, and without a word returned to my seat. There was no need for words--at least none that I could imagine, unless Perry desired to pray. And I was quite sure that he would, for he never left an opportunity neglected where he might sandwich in a prayer. He prayed when he arose in the morning, he prayed before he ate, he prayed when he had finished eating, and before he went to bed at night he prayed again. In between he often found excuses to pray even when the provocation
seemed far-fetched to my worldly eyes--now that he was about to die I felt positive that I should witness a perfect orgy of prayer--
if one may allude with such a simile to so solemn an act.
But to my astonishment I discovered that with death staring him in the face Abner Perry was transformed into a new being. From his lips there flowed--not prayer--but a clear and limpid stream of undiluted profanity, and it was all directed at that quietly stubborn piece of unyielding mechanism.
"I should think, Perry," I chided, "that a man of your professed religiousness would rather be at his prayers than cursing in the pres-
ence of imminent death."
"Death!" he cried. "Death is it that appalls you? That is nothing by comparison with the loss the world must suffer. Why, David
within this iron cylinder we have demonstrated possibilities that science has scarce dreamed. We have harnessed a new principle,
and with it animated a piece of steel with the power of ten thousand men. That two lives will be snuffed out is nothing to the world calamity that entombs in the bowels of the earth the discoveries that I have made and proved in the successful construction of the 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 the 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
