At last it was determined, beyond any doubt, that even the outer skin was uninjured. Not so much as a dent could be found in it. "By the favor of Providence," said Cosmo Versál, as his great head emerged from a manhole, "the Ark has touched upon a place where the rocks are covered with soil, and no harm has come to us. In a very short time the rising water will lift us off." "And, with my consent, you'll do no more navigating over hills and mountains," grumbled Captain Arms. "The open sea for the sailor." The covers were carefully replaced, and the party, in happier spirits, returned to the upper decks, where the good news was quickly spread. The fact was that while the inspection was under way the Ark had floated off, and when Cosmo and the captain reached their bridge the man who had been left in charge reported that the vessel had swung halfway round. "She's headed for the old Atlantic," sung out Captain Arms. "The sooner we're off the better." But before the captain could signal the order to go ahead, Cosmo Versál laid his hand on his arm and said: "Wait a moment; listen." Through the lashing of the rain a voice penetrated with a sound between a call and a scream. There could be no doubt that it was human. The captain and Cosmo looked at one another in speechless astonishment. The idea that any one outside the Ark could have survived, and could now be afloat amid this turmoil of waters, had not occurred to their minds. They experienced a creeping of the nerves. In a few minutes the voice came again, louder than before, and the words that it pronounced being now clearly audible, the two listeners could not believe their ears. "Cosmo Versál!" it yelled. "Cosmo-o-o Ver-sá-al! A billion for a share! A _billion_, I say, a _bil-li-on_ for a share!" Then they perceived a little way off to the left something which looked like the outline of a boat, sunk to the gunwales, washed over by every wave; and standing in it, up to their waists in water, were four men, one of whom was gesticulating violently, while the others seemed dazed and incapable of voluntary movement. It was the boat of levium that had been thrown out of the wreckage when the battleship ran down the Municipal tower, and we must now follow the thread of its adventures up to the time of its encounter with the Ark. As the boat was driven westward from the drowned site of Madison Square it gradually freed itself from the objects floating around, most of which soon sunk, and in an hour or two its inmates were alone--the sole survivors of a dense population of many millions. Alone they were in impenetrable darkness, for, as we have said, night had by this time once more fallen.
