The preparation cost us half-an-hour of time, and when all was ready, the captain went to the engine-room and brought Karl to the top of the ladder; but there the German stayed, nor did threats or entreaties move him.
"He'll die with the ship," said Black, "and I don't know that he isn't wise;" but he held out his hand to the genius of his crime, and after a great grip the two men parted.
For ourselves, we stepped on the frailest craft with which men ever faced the Atlantic, and at that moment the first of the ironclads fired another shell at the nameless ship. It was a crashing shot, but it had come too late to serve justice, or to wreck the ship of mystery; for Karl had let the hydrogen into the cylinders unchecked, and with a mighty rush of flame, and a terrific explosion, the craft of gold gave her "Vale!" And in a cascade of fire, lighting the sea for many miles, and making as day the newly-fallen night, the golden citadel hissed over the water for one moment, then plunged head-long, and was no more.
A fierce fire it was, lighting sea and sky—a mighty holocaust; the roar of a great conflagration; the end of a monstrous dream. And I thought of another fire and another face—the face of Martin Hall, who had seen the finger of Almighty God in his mission; and I said, "His work is done!"
