"Smoke ahead, Frank," he called.
"Hope it's the Queen Mary" replied the lad. "It should be if I have calculated correctly."
A few moments later the outline of a large ship of war loomed up ahead.
"Can you make her out yet?" asked Jack.
"No; but she's built like the Queen Mary"
The hydroplane sped on.
"By Jove! She is the Queen Mary" cried Frank, a few moments later.
"We're in luck."
Frank was right. As the hydroplane drew nearer it was plain to make out that the vessel was the giant battleship the lads had quitted the day before.
"Wonder what Captain Raleigh will think of our information?" said
Frank, with a chuckle.
"Don't know. We've been pretty fortunate, though. I hope we are in time."
