"Then I called you up," went on Mr. Damon, "and I was surprised to learn you hadn't seen Tom. There must be something wrong, I think." "I'm sure of it!" exclaimed Ned. "Let's find Mr. Swift. And what's this about his going to meet me over at the place of that farmer, Mr. Kanker, where we had the trouble about the barn Tom demolished?" "I hardly know, myself. Perhaps Mr. Swift can tell us." But Mr. Swift was able to throw but little light on Tom's disappearance--whether a natural or forced disappearance remained to be seen. "No matter where he is, we'll get him," declared Ned. "He hasn't been away a great while, and it may turn out that his absence is perfectly natural." "And if it's due to the plots of any of his rivals," said Mr. Damon, "I'll denounce them all as traitors, bless my insurance policy, if I don't! And that's what they are! They're playing into the hands of the enemy!" "All right," said Ned. "But the thing to do now is to get Tom. Perhaps Mrs. Baggert can help us." It developed that the housekeeper was of more assistance in giving information than was Mr. Swift. "It was several hours ago," she said, "that the telephone rang and some one asked for Tom. The operator shifted the call to the phone out in the tank shop where he was, and Tom began to talk. The operator, as Tom had instructed her, listened in, as Tom wants always a witness to most matters that go on over his wires of late." "What did she hear?" asked Ned eagerly. "She heard what she thought was your voice, I believe," the housekeeper said. "Me!" cried the young bank clerk. "I haven't talked to Tom to-day, over the phone or any other way. But what next?" "Well, the operator didn't listen much after that, knowing that any talk between Tom and you was of a nature not to need a witness. Tom hung up and then he came in here, quite excited, and began to get ready to go out." "What was he excited about?" asked Mr. Damon. "Bless my unlucky stars, but a person ought to keep calm under such circumstances! That's the only way to do! Keep calm! Great Scott! But if I had my way, all those German spies would be--Oh, pshaw! Nothing is too bad for them! It makes my blood boil when I think of what they've done! Tom should have kept cool!" "Go on. What was Tom excited about?" Ned turned to the housekeeper. "Well, he said you had called him to tell him to meet you over at that farmer's place," went on Mrs. Baggert. "He said you had some news for him about the men who had tried to get hold of some of his tank secrets, and he was quite worked up over the chance of catching the rascals." "Whew!" whistled Ned. "This is getting more complicated every minute. There's something deep here, Mr. Damon." "I agree with you, Ned. And the sooner we find Tom Swift the better. What next, Mrs. Baggert?" "Well, Tom got ready and went away in his small automobile. He said he'd be back as soon as he could after meeting you."
