"No government at all. But I think we ought to have a try for it, Mr. Bentley."

"Explain."

"Well, I have just learned, most accidentally, that the Swifts are going after sunken treasure—three hundred thousand dollars in gold bullion."

"Sunken treasure? Where?

"I don't know exactly, but off the coast of Uruguay," and Mr. Berg rapidly related what he had overheard Tom tell Mr. Damon. Mr. Bentley was much excited and impatient for more details, but his agent could not give them to him.

"Well," concluded the senior member of the firm of submarine boat builders, "if the Swifts are going after treasure, so can we. Come to Philadelphia at once, Mr. Berg, and we'll talk this matter over. There is no time to lose. We can afford to forego the Government prize for the chance of getting a much larger one. We have as much right to search for the sunken gold as the Swifts have. Come here at once, and we will make our plans."

"All right," agreed the agent with a smile as he hung up the receiver. "I guess," he murmured to himself, "that you won't be so high and mighty with me after this, Tom Swift. We'll see who has the best boat, after all. We'll have a contest and a competition, but not for a government prize. It will be for the sunken gold."

It was easy to see that Mr. Berg was much pleased with himself.

Meanwhile, Tom and Mr. Damon had reached Atlantis, and had purchased the oil. They started back, but Tom took a street leading toward the center of the place, instead of striking for the beach path, along which they had come.

"Where are you going?" asked Mr. Damon.
