“No matter about that now!” interrupted Beatrice. “We've got all the time there is! Even if it takes five years, what of that? What are months or even years in the life-history of the world?”

Stern kept silence again. In his mind he was revolving a hundred vital questions of shelter, feeding, acclimatization for these men, now to be transported from a place of dark and damp and heat to the strange outer regions of the surface-world.

Plainly he saw it would be a task of unparalleled skill, delicacy, and difficult accomplishment; but his spirits rose only the higher as he faced its actual details. After all that he and Beatrice had been through since their wakening in the tower, he feared no failure to solve any questions that now might rise. By care, by keeping the Folk at first in caves, then gradually accustoming them to stronger and brighter light, more air, more cold, he knew he could bridge the gap of centuries in a few years.

Ever adaptable, the human body would respond to changed environments. Patience and time--these would solve all!

And as for this Folk's barbarism, it mattered not. Much better such stock to rebuild from than some mild, supine race of far higher culture. To fight the rough battles of life and re-establishment still ahead, the bold and warlike Merucaans were all that he could wish.

“Imagine me as a school-teacher,” suddenly exclaimed the girl, laughing: “giving the children A B C and making them read: ‘I see the cat’--when there aren't any cats nowadays--no tame ones, anyhow! Imagine--”

Sh-h-h!” cautioned Stern. “Don't waste your energies imagining things just yet. There's more than enough real work, food-getting, house-building in caves, and all that, before we ever get to schools. That's years ahead yet, education is!”

Silence again, save for the strong and ceaseless chatter of the engine, that, noisy as a score of mowing machines, flung its indomitable challenge to gravitation out into the fathomless void on every hand.

“Allan! Allan! Oh, a star! Look, look! A star!

The girl was first to see that blest and wondrous thing. Hours had passed, long, weary hours; steadily the air-pressure had sunk, the vapors thinned; but light had not yet filtered through the mists. And Allan's mind had been sore troubled thereat. He had not thought of the simple reason that they were reaching the surface at night.
