Soon the bell was rising. To assist, they began to pump the water out of the bell. The demons swarmed all around the bell, but did not dare to touch the glass sides or the crab-like claws. Soon the bell passed from the zone of submarine light and then the demons dropped back, for they could not breathe in the upper portions of the ocean. The bell cleared of water, father and son took off their diving suits. "Thank Heaven we are out of that!" came in the sign language from Amos Fearless. "We were lucky to escape," answered Dave, earnestly. "But, father, the treasure--how will we ever get at it, with those demons around?" At this the old diver shook his head slowly. It was a problem difficult, if not impossible, to solve. "I wouldn't like to meet those fellows again for a million dollars," went on Dave. And his father agreed with him. It seemed a long while before they emerged from the ocean, at the side of the _Swallow_. Those on the ship lost no time in bringing them on board and questioning them regarding what they had discovered. The story about the demons was listened to with keen interest by Doctor Barrell. "Ah, they must belong to the lost order of chilusia damondaribytis!" cried the learned man. "They are supposed to have lived at one time upon the lost continent of Atlantis. But if so, how did they come here, in the middle of the Pacific? It is a great mystery. You must bring up one of them in the net." "Thanks, but I don't want the job," replied Dave, quickly. "But, my dear young man, think of the interest to science--the--the great fame it will bring you." "Not if the chilu-what's-his-name chews me up, doctor. You just ought to see them. Why, they are enough to give you bad dreams for a month." "Then I will go down myself in the diving bell. If it is light, as you say, perhaps I can get some snapshot photographs of them," went on the learned man. "What if they take it into their heads to smash the diving bell to pieces?" "Cannot you keep them at a distance with the submarine firearms?" "Hardly; but I was thinking we might take down some submarine torpedoes," went on Dave, suddenly. The matter was talked over for fully an hour, and at last it was decided that another trial should be made the next day, and the divers should take along two submarine torpedoes, with which to blow up the demons should the latter molest them. In the meantime Captain Broadbeam had his glass trained upon the _Raven_, and presently he announced that the diving bell from that ship was coming up. All watched eagerly for the reappearance of Vixen and Walton, the rival divers. At last the men were hauled up on the deck of the _Raven_. It was seen that Walton was injured and had to be carried to the cabin by some of the sailors.
