"Well, maybe you're right," agreed Tom; "but I'll feel better when I see my tank in her shed. Let's have some more of that concentrated porterhouse steak of yours, Ned. It is good, and it fills out my stomach, which was getting more intimate with my backbone than I liked to feel."
More of the really good confection and another drink of refreshing water made Tom feel better, and he was soon able to walk along without staggering from weakness.
"And now let's get out of here," advised Ned, "unless you've left something back in that vault you want, Tom," and he motioned to his chum's late prison.
"Nothing there but bad memories," was the reply, with a rueful smile. "I'm as ready to go as you are, Ned. It was good of you and Mr. Damon to come for me, and you"—and he looked questioningly at Mr. Kimball.
"If it hadn't been for Mr. Kimball and his boy, we wouldn't have found you—at least so soon," said Ned, and he told of the finding of the note and what had followed.
"That's the only way I could think of for getting help," said Tom. "They took every scrap of paper from me, but I found some in the lining of my hat—some I'd stuffed in after I had a hair cut and my hat was too large. For a pencil I used burnt matches. Oh, but I'm glad to be out!" and he breathed deep of the fresh air.
"How did you get in there?" asked Ned wonderingly.
"Those fellows—of course. The German plotters, I'm going to call them, for I believe that Blakeson and his gang—though I didn't see him—are really working in the interests of Germany to get the secret of my tank."
"Well, they haven't got her yet," said Ned, "and they're not likely to now. Go on, Tom, if you feel able tell us in a few words what happened. We've been trying to think, but can't."
"Well, it all happened because I didn't think enough," said Tom, who was rapidly recovering his strength and nerve. "When I got that message that seemed to come from you, Ned, I should have known better than to take a chance. But it seemed genuine, and as I had no reason to suspect a trap, I started off at once. I thought maybe Kanker had repented and was going to make amends for all the trouble he caused.
