"No, Tom, you won't. If you did leave some one on guard, there'd be too much chance of their getting the best of him. You must take your tank away with you." "But how can I? I can't put up three thousand dollars in cash, and he says he won't take a check for fear I'll stop payment. I see his game, but I don't see how to block it." "But I do!" cried Ned. "What!" exclaimed Tom. "You don't mean to say, even if you do work in a bank, that you've got three thousand in cash concealed about your person, do you?" "Pretty nearly, Tom, or what is just as good. I have that amount in Liberty Bonds. I was going to deliver them to a customer who has ordered them but not paid for them. They are charged up against me at the bank, but I'm good for that, I guess. Now I'll loan you these bonds, and you can give them to this cranky old farmer as security for damages. Mind, don't make them as a payment. They're simply security--the same as when an autoist leaves his car as bail. Only we don't want to leave our car, we'd rather have it with us," and he looked over at the tank, bristling with splinters from the demolished barn. "Well, I guess that's the only way out," said Tom. "Lucky you had those bonds with you. I'll take them, and give you a receipt for them. In fact, I'll buy them from you and let the farmer hold them as security." And this, eventually, was done. After much hemming and hawing and consultation with the men in the automobile, Mr. Kanker said he would accept the bonds. It was made clear that they were not in payment of any damages, though Tom admitted he was liable for some, but that Uncle Sam's war securities were only a sort of bail, given to indicate that, some time later, when a jury had passed on the matter, the young inventor would pay Mr. Kanker whatever sum was agreed upon as just. "And now," said Tom, as politely as he could under the circumstances, "I suppose we will be allowed to depart." "Yes, take your old shebang offen my property!" ordered Mr. Kanker, with no very good grace. "And if you go knocking down any more barns, I'll double the price on you!" "I guess he's a bit roiled because he couldn't hold the tank," observed Ned to Tom, as they walked together to the big machine. "His friends--our enemies--evidently hoped that was what could be done. They want to get at some of the secrets." "I suppose so," conceded Tom. "Well, we're out of that, and I've proved all I want to." "But I haven't--quite," said Ned. "What's missing?" asked his chum, as they got back in the tank. "Well, I'd like to make sure that the fellow who ran from the factory was the same one I saw sneaking out of the barn. I believe he was, and I believe that Simpson's crowd engineered this whole thing." "I believe so, too," Tom agreed. "The next thing is to prove it. But that will keep until later. The main thing is we've got our tank, and now I'm going to get her ready for France." "Will she be in shape to ship soon?" asked Ned.
