"She's seen us!" cried Frank, and dropped into a seat, laughing happily.
Both lads watched silently the oncoming cruiser.
"Can you make her out?" asked Frank at length.
Jack rose and looked sharply across the water.
"Yes," he said finally. "She is the Cumberland."
A small boat was lowered from the cruiser and put off toward them. Soon it scraped alongside the boys' craft, and they were taken aboard where they were received with expressions of great surprise, both by the officer in command and by members of the boat's crew.
"How did you get away out here?" asked the surprised boatswain.
Briefly Jack explained.
"By Jove!" exclaimed the officer when the lad had concluded his story. "You certainly have seen excitement. And so you blew up the German submarine?"
"My friend here did," replied Jack, indicating Frank.
