The senator dropped the receiver from his hand in his disappointment.

"Too late! The code is lost to the United States for good, and those rascals have escaped!"

But Jack suddenly sprang forward. His cheeks were aflame with excitement.

"Senator," he cried. "There is still a chance."

"I fail to see it," said Mr. Rivers.

"Get the line on the wire again, sir, and find out if the Southern Star has a wireless."

"But what—Jove, boy! I see your plan now."

Eagerly the Senator snatched up the receiver again. Before long connection was again established.

"The Southern Star has a wireless," he exclaimed. "Her call is S. X. A., and now for your plan, my boy."

"Show me to your wireless room, will you, Ned?" said Jack, subduing the excitement in his voice with a struggle.
