"Casey and I are about the same size," he muttered. "But what the deuce does it all mean?"

He went to sleep with the turbines humming full speed in his ears; but he wakened when they were reduced to cruising speed. Looking at his watch in the light from the wardroom, he found that it was half-past two; and, on stepping out for a look at the telltale, he found the boat heading due south.

"Back in the pocket," he said, as he returned to his room.

But the engines did not stop, as he partly expected; they remained at half speed, and the boat still headed south when he wakened at breakfast-time.

CHAPTER XXI

After breakfast, King, one of the machinists, and a pleasant-faced young man, came aft with an ensign, a hammer, chisel, and paint pot.

"This is work, sir," he said, as he passed, tipping his cap politely to Miss Florrie. "Should have been done before."

He went to the taffrail, and, leaning over with the hammer and chisel, removed the raised letters that spelled the boat's name. Then he covered the hiatus with paint, and hoisted the ensign to the flagstaff.

"Now, sir," he remarked, as he gathered up his tools and paint pot, "she's a government craft again."

"I see," commented Denman; and then to Florrie as King went forward: "They're getting foxy. We're steaming into the crowd again, and they want to forestall inspection and suspicion. I wonder if our being allowed on deck is part of the plan? A lady and an officer aft look legitimate."
