"I'm ready!" laughed Jack. "I want to hear that noise again."
"Do you think there are men down there removing the gold?" asked Jack.
CHAPTER VIII
ON GUARD UNDER THE SEA
"If there is anybody at work on the wreck," Ned replied, "they may be removing the gold or they may be searching the vessel for incriminating documents."
"I guess any documents found down there will be pretty wet," laughed
Jack.
"They may be in sealed boxes," Ned replied. "Anyway, if there are important documents on board they might be rendered legible by proper and judicious handling." "Here we go, then," Jack exclaimed. "I'll expel the water in the tanks until the Sea Lion rests at the right altitude, over the wreck, and we can enter by way of the decks."
"But what will the other fellows be doing while we are getting into position?" asked Frank.
"Gettin' ready to cut our lines, probably," interposed Jimmie.
"That's a fact," Jack said. "If there are men working in the ship they must be supplied with air by a submarine. How could that be done, I'd like to know."
