"The Arethusa!" Operative Carnes of the United States Secret Service sprang to his feet. "You said the Arethusa? There were no survivors!"
"I believe that I am the only one."
"Where have you been hiding and why haven't you reported the fact of your rescue to the proper authorities? Tell the truth; I'm a federal officer!"
Carnes flashed the gold badge of the Secret Service and an expression of anger crossed Mitchell's face.
"If I had wished to talk to an officer I could have found plenty in New York," he said shortly. "I came to Washington in order to tell my story to Dr. Bird."
The seaman and the detective glared at one another for a moment and then Dr. Bird intervened.
"Pipe down, Carnes," he said softly. "Mr. Mitchell undoubtedly has reasons, excellent reasons, for his actions. Sit down, Mr. Mitchell, and have a cigar."
MITCHELL accepted the cigar which the doctor proferred and took a chair. He lighted the weed and after another glance of hostility toward the detective he pointedly ignored him and addressed his remarks to Dr. Bird.
"I have no objection to telling you why I haven't spoken earlier, Doctor," he said. "When the Arethusa sank, I must have hit my head on something, for the next thing I knew, I was in the Marine Hospital in New York. I had been picked up unconscious by a fishing boat and brought in, and I lay there a week before I knew anything. When I knew what I was doing I heard about the loss of my ship and was told that there were no survivors, and I didn't know what to do. The story I had to tell was so weird and improbable that I hesitated to speak to anyone about it. I was not sure at first that it was not a trick of a disordered brain, but since my head has cleared I am convinced of the truth of it ... and yet I know that it can't be so. I have read about you and some of the things you have done, and so as soon as I was able to travel I came here to tell you about it. You will be better able to judge than I, whether what I tell you really happened or was only a vision."
Dr. Bird leaned back in his chair and put the tips of his fingers together. Long, tapering fingers they were, sensitive and well shaped, though sadly marred by acid stains. It was in his hands alone that Dr. Bird showed the genius in his make-up, the artistry which inspired him to produce those miracles of experimentation which had made his name a household word in the realm of science. Aside from those hands he more resembled a pugilist than a scientist. A heavy shock of unruly black hair surmounted a face with beetling black brows and a prognathous jaw. His enormous head, with a breadth and height of forehead which were amazing, rose from a pillar-like neck which sprang from a pair of massive shoulders and the arching chest of the trained athlete. Dr. Bird stood six feet two inches in his socks, and weighed over two hundred stripped. As he leaned back a curious glitter, which Carnes had learned to associate with keen interest, showed for an instant in his eyes.
"I will be glad to hear your story, Mr. Mitchell," he said softly. "Tell it in your own way and try not to omit any detail, no matter how trivial it may be."
THE seaman nodded and sat silent for a moment as though marshaling his thoughts.
"The story really starts the afternoon of May 12th," he said, "although I didn't realize the importance of the first incident at the time. We were steaming along at good speed, hoping to make New York before too late for quarantine, when a hail came from the forward lookout. I was on watch and I went forward to see what was the matter. The lookout was Louis Green, an able bodied seaman and a good one, but a confirmed drunkard. I asked him what the trouble was and he turned to-
