"The first man to go down from the _MacLean_ was Charley Melrose, an expert diver. He went down in a pressure outfit to the bottom and started to work. Everything was going along fine until the telephone suddenly rang and the man who answered it heard him say, 'Raise me, for God's sake! Hurry!' The signal for raising was given, but they hadn't got him more than thirty feet from the bottom before there came a tug on the line and he was gone! The air line, the lifting cable and the telephone cord floated free and were reeled in. Melrose had been plucked off the end of that line as you or I would pluck off a grape." * * * * * Dr. Bird leaned forward with the curious glitter again in his eye. "Go on," he said tersely. "Blake, the other diver, donned a suit and insisted on being lowered at once. Starley tried to dissuade him but he insisted on going down. They lowered him over the side with a twelve-foot steel-shod pike in his hand. He never got to the bottom. He had not been lowered more than a hundred feet when a scream came over the telephone, and again there was a jerk on the lines which threatened to wreck the reel--and the line came aboard with no diver on the end of it. At the same time, Starley told me, the sea boiled and churned as though the whole bottom were coming up, and his ship was tossed about as though it were in a violent storm, although it was calm enough for forty fathom salvage work and that is pretty quiet, you know. Half the time his screws were out of water and he had a hard time to keep from being capsized. He fought his way out of the disturbed area, and as soon as he did, it started to quiet down, and in ten minutes it was calm again. "Starley was pretty badly shaken and besides he had lost both of his divers, so he came in and I saw him at the dock. When I heard his yarn, I took him into my confidence and told him what I had seen and that I proposed coming to you and asking your advice. I was afraid until I heard his story that it was merely a vision that I had had, but it certainly was no vision that plucked those two divers off their lines." "Has Captain Starley told that story to anyone else yet?" "No, Doctor, he hasn't. He promised not to talk until after I had seen you. I'll vouch for him; he'll keep his word through anything; and he is keeping his whole crew on board until he hears from me." * * * * * Dr. Bird sprang to his feet. "Mr. Mitchell," he said energetically, "you have shown excellent judgment. Wire Captain Starley that you have seen me and that he is to hold his crew on board and to talk to no one until I get there. Carnes, telephone the Chief of Naval Operations and ask him to receive me in conference at once. Have him get the Secretary of the Navy in, too, if he is available. When you have finished that, telephone Bolton that you will be away from Washington indefinitely."
