"I BOUNDED UPWARD FULLY SIX FEET."
"You trifle with me; I weigh over one hundred and fifty pounds; how have I lost weight? It is true that I have noticed the ease with which we have recently progressed on our journey, especially the latter part of it, but I attribute this, in part, to the fact that our course is down an incline, and also to the vitalizing power of this cavern air."
"This explains part of the matter," he said; "it answered at the time, and I stated a fact; but were it not that you are really consuming a comparatively small amount of energy, you would long before this have been completely exhausted. You have been gaining strength for some hours; have really been growing younger. Your wrinkled face has become more smooth, and your voice is again natural. You were prematurely aged by your brothers on the surface of the earth, in order that when you pass the line of gravity, you might be vigorous and enjoying manhood again. Had this aging process not been accomplished you would now have become as a child in many respects."
He halted before me. "Jump up," he said. I promptly obeyed the unexpected command, and sprung upward with sufficient force to carry me, as I supposed, six inches from the earth; however I bounded upward fully six feet. My look of surprise as I gently alighted, for there was no concussion on my return, seemed lost on my guide, and he quietly said:
"If you can leap six feet upward without excessive exertion, or return shock, can not you jump twenty feet down? Look!"
And he leaped lightly over the precipice and stood unharmed on the stony floor below.
Even then I hesitated, observing which, he cried:
"Hang by your hands from the edge then, and drop."
I did so, and the fourteen feet of fall seemed to affect me as though I had become as light as cork. I fluttered to the earth as a leaf would fall, and leaned against the precipice in surprised meditation.
