“Well, that mast was the aerial of a wireless. I don’t know what he uses it for, but apparently he has one. Now that we have the Denckel apparatus fixed to send waves to any given point, we can send off waves of all kinds to Tokio, calling him and recalling him, until we get a wave which his receiver will take. Then we can set up a straight, wireless receiving station here to take his answer.” “What will you say to him?” Tom asked. “I’ll just say,--‘To the man who stopped all war. War is over. All nations are disarming. Reply to us.’” “It’s worth trying, anyway,” said Tom, with an air of finality. “I’ll go right to work setting up a receiving plant. I can do that, all right, but I can’t send Morse through our machine.” “If you’ll look out for the construction end of it, I can send Morse over an ordinary key,” I suggested. “Then that’s settled,” said Tom. “I can set up a wireless that will receive any waves sent from Japan, and I can set up a duplicate of the wave-measuring machine that will send messages straight to Tokio, by means of an ordinary Morse key. Where had we better run our aerial?” “Down by the shore,” said Dorothy. “We want to avoid the interfering action of the currents that are loose in and around the city.” “There’s one thing you’ve forgotten,” I interposed. “If ‘the man’ is in a submarine, your message may not reach him under water.” “He’ll spend most of his time on the surface,” said Tom. “With a first-class submarine he could spend two months under water at a time, but he wouldn’t want to.” “Don’t spend any more time in discussion, boys,” interrupted Dorothy. “We must reach him the first moment possible, before any other ship goes down. Meanwhile, Jim, you want to get this to the paper, don’t you?” “I surely do,” I responded, and I hurried off to wire the London office. I sent my telegram over our private line, and waited for the answer. In five minutes it came back. “Too late, this time, my boy. Japanese first-class battleship disappeared in broad daylight in the harbor of Tokio. They sent it on here immediately, and we have had it for some minutes. Rest on your laurels.” Signed, Maxwell.
