Weddigen still reclined on deck. It had been a long, hard fight under water and he, too, had somewhat overstayed his time limit. His friends in the crew were fêting him. They crowded about, patting him on the back and congratulating him for his plucky and successful efforts to get at the lost treasure. "Wait till we get back to Bridgeford--the swellest time you ever had in your life," shouted one enthusiast. All of this adulation pleased Weddigen. The rôle of the hero appealed to him and he was enjoying the situation immensely. Meanwhile Jay was slowly but surely returning to life. The oxygen tank had performed yeoman service. Color was coming back into the face and circulation had been restored. A stimulant was offered, but the stout-hearted lad declined it, smilingly preferring to keep the temperance pledge that he had taken before he had left home to go to school. "Thanks, Cap, but I'm coming back in fine shape," he mumbled, while Dick fairly beamed over the recovery of his chum. In a few minutes Jay was able to sit up. He drank eagerly the cup of hot black coffee that was offered him. He was very weak from his trying ordeal, and no one ventured to ask him about his hazardous trip to the _Dominion_ and his narrow escape from death. By and by Jay motioned Dick to come closer. "Did Weddigen land any treasure?" he asked with an inquisitive look. Dick launched into the story, telling how the strong box had been hauled over the side amid wild jubilation and taken below into Captain Austin's quarters. "Are you sure there were diamonds in the chest?" persisted Jay. "Sure, Mike," responded his chum. "Oodles of them worth thousands of dollars. Glittering cut stones; a young fortune big enough to put us all on easy street for the rest of our lives if they belonged to us." Jay pondered the situation for a moment. In his eyes was a queer look that neither Dick nor Larry Seymour, who had joined the group, could fathom. "Is Weddigen still on deck?" persisted Jay. "Still back there resting up while the crew make a fuss over him," replied Larry. "All right, now, Larry, do what I tell you, please," said Jay. "Just stroll back there casually and look him over without arousing suspicion. See if you don't notice a narrow slit of a pocket on the inside of the right leg of his armor suit, buttoned over with a flap. When he gets up to take off his diving suit just manage to accidentally flip that pocket open and then keep your eyes on it." "Why, what do you mean?" offered Larry, perplexed by the directions given him by Jay. "Remember, I never fooled you in my life, old friend," answered the latter. "Just do what I tell you, and perhaps you'll have a bit of a surprise party." Jay was weakened by the exertion of talking and sank back to rest again with closed eyes. Withdrawing a few paces, Dick and Larry discussed the suggestions made by Jay. "Think he is still a little dippy as a result of his experience?" questioned Larry.
