"Through all that day we watched the great current shooting ceaselessly up through the calmer waters about it, and through the next, and knew that on earth the waters must already be rising inch by inch, and that they would creep up, inch by inch and foot by foot, until they had covered all earth's fields and forests and cities and highest peaks, until earth itself was covered miles deep with this sea of hell, and at its bottom the slug-people reigned triumphant. Then, at last, the agony of our despair broke forth, and we seized at once upon a chance for escape which presented itself. "It was in a suggestion made by Evans, the submarine's commander, that we saw our chance. His plan seemed suicidal, almost, but it was still a chance, so we ignored the risks. Waiting for some hours until the street outside our prison had emptied somewhat of the passing slug-people, we took from the submarine's equipment a long, slender drill of steel, and with this, held and guided by two seamen, set to work on the metal wall of our prison. At first the metal seemed too hard for the drill to affect, but gradually it bit into it, deeper and deeper. Inch by inch it crept on into the thick metal wall, while we watched anxiously. The hours were passing swiftly, and in the distance we could see the mighty current from the pit still roaring upward, but at last, when it seemed that the wall was too thick for us, the drill broke through. "Before we could withdraw it, it had been knocked inward toward us with terrific force by the pressure of the waters outside, and through the two-inch hole it left came shooting inward a solid stream of water of terrific force. In a moment that jet had filled the great room to a depth of a foot, and hastily we splashed toward our submarine, clambering up and inside it and shutting tightly the heavy doors. From the port-holes we could see the waters in the room swiftly rising, until within a few more minutes they had risen sufficiently to float the submarine, which had been lying on the bare metal floor of the great room. "Instantly Evans gave an order, and at once the craft's motors began to hum and its reversed propellers to thrash the waters, backing us against the wall opposite the great doors. There we paused a moment, and then another order sent the boat leaping across the great room through the waters like a living thing, toward the inner of the two great doors, which could be opened only from the outside. With a great ramming shock the craft's prow struck the door; for this was our plan, to batter down the two doors if possible and make our escape. The door, we saw, had been shaken by the blow, its thick, transparent metal deeply dented, but it still hung fast; so again the submarine retreated to the opposite wall and again leapt forward to crash against the barrier.
