Once in the bell he hardly knew what to do next. To shut the door under the circumstances was out of the question. Yet he could not remain below the surface forever. But while he was meditating upon the unexpected turn of affairs some other fish came to his aid. They were long, fat fellows, with stomachs on them resembling balloons. There were a score or more of them, and they began to gobble down the little fish as rapidly as they could swallow them. A fight ensued between the little fish and the big fish, and in the end nearly all of the fish of both sorts left the vicinity of the diving bell for parts unknown. Realizing what was going on, Dave watched his chance and when only a few of each kind of fish remained in the diving bell he shut the door. Then he began to pump out the water, and at the same time signaled to those on the ship to raise him to the surface. "A splendid haul!" cried Doctor Barrell, on examining his strange catch. "Two spiral whipsnaps, to use the vulgar name, and half a dozen fish which are new to science." Captain Broadbeam had taken up one of the little fish and was examining it with interest. The fish was dead, having been cut open during the struggle in the diving bell. "He's got something inside of him that don't belong there, I reckon," said the captain. "Creation, look here!" And he held up--a small gold coin! "A gold coin!" cried Dave. "A Chinese piece, too!" "You are right," said Doctor Barrell. "Perhaps it came from the sunken treasure," put in Amos Fearless, who stood near. "Perhaps." "Then the treasure must be down here, at the bottom of the ocean," added Dave. "It's not unlikely," said the doctor. "Although such a fish might swim a long distance with such a coin in his insides." While the party was talking the matter over, and Doctor Barrell was preparing to place the spiral fish in a safe place, there came a cry from the lookout: "Sail oh!" "Where away?" cried Captain Broadbeam. "Dead ahead, sir." "Can you make her out?" "A steamer, sir." "Perhaps it is the _Raven_," said Dave. And his heart gave a leap. Slowly the newcomer came closer until, at noon, she was within hailing distance. She was really the _Raven_ and she came up boldly, with Lemuel Hankers, Bart, and several others on her deck. The _Raven_ would have gained the spot several days before, but an unexpected breakdown of her machinery had caused a delay. The wait was maddening to Lemuel Hankers and his son, yet their rage did them no good. The _Raven_ came to a standstill when within hailing distance of the _Swallow_. "_Raven_, ahoy!" shouted Captain Broadbeam, through his speaking trumpet. "Ahoy, the _Swallow_!" came back from Captain Nesik. "You're a pretty set of rascals!" burst out the honest commander of the Government vessel. "Don't talk that way to us!" retorted Captain Nesik. "Why didn't you rescue us from the savages?" "We were running on a reef and had to look after our ship," was the lame excuse.
