The two words "our plane" had all of the effect on Dawson of a swift punch to the jaw. Impulsively he raced his eyes along the length of the U-boat, and particularly the forward end. It was then that he spotted telltale objects that told him the truth, and cleared up a little of the mystery of yesterday's meeting in the air with that strange seaplane. In short, he saw a plane hoist secured to the port side of the forward deck. It was fastened down in a horizontal position, but it could be raised upright at a moment's notice. He also saw that just about the entire forward deck consisted of two hatch covers that could be folded back to make a good sized opening in the deck. And although he could not look down through the steel plates to what was below, he had the very definite feeling that stowed neatly in the forward hold of the U-boat was that strange type seaplane with its wings folded back. Airplane-carrying submarines were nothing new to Dawson, or to Freddy Farmer, either. But it was a bit of a shock to realize that they had been shot down by such a craft. And, also, that they had been rescued by the mother U-boat of the plane. "Yes, yes, I know!" Dawson heard the Nazi commander grunt impatiently at the Jap. "Of course our plane shot them down. But you do not know these American dogs as I do. Let them lie long enough and before they realize it they are telling you the truth. You will see what I mean. Well, take them to my quarters, and wait. This is a bad hour to remain on the surface too long. We will submerge at once." The Nazi had spoken in German, and both Dawson and Freddy Farmer understood him perfectly. However, both were very careful not to let that fact show in their faces. As a matter of fact, they stared puzzle-eyed at the Nazi and then looked enquiringly at each other. The Nazi saw them do that and laughed harshly. "Do not worry, swine," he spoke in harsh English. "When the Fuehrer is in your White House all of you American dogs will be taught to speak German. There will be but one language then. German!" The Nazi nodded violently, and then snapped a glittering eye at the Jap naval officer as though inviting him to take issue with his words. The Jap, however, refused to take issue. He simply smiled politely and then motioned for Dave and Freddy to climb over the lip of the conning tower hatch and start down inside the boat. When they reached the bottom of the conning tower ladder which ended in the central control room, and nerve center of the U-boat, the Jap didn't give them so much as half a chance to look around. He had his gun out then, and he jabbed them both hard in the back and pointed aft. The pain from the jab made firecrackers go off in Dave's brain. And for one crazy instant he was tempted to wheel around and drive both fists into that slant-eyed, hateful face. Common sense, however, came to his rescue instantly and he checked the urge and went stumbling along in step with Freddy Farmer.
