"Are you hurt?" asked Alfred, as Ralph dropped down, but he was reassured as the latter arose. For the moment the captain's gaze was averted, when, quick as thought, the officer's hand touched a lever.

The captain smiled, as he said: "I am afraid the valve of the submerging tank will not work; I prefer running on the surface. But, in the meantime, as I am commander of this vessel, and I notice that you are trying to interfere, I shall have to restrict your movements somewhat."

Saying this he drew a small cord from his pocket and instructed Alfred to bind the arms at the wrists. The hands of the officer were then carried around to the back and the cord fastened to a stanchion at one side, where he was out of reach of the instrument board.

This gave the captain an opportunity to examine Ralph's wound. The latter had quickly rallied. It was the shot, coupled with the extreme tension, which caused him momentarily to collapse, for it was found that the wound had passed through the fleshy part of the arm above the elbow.

"I suppose you want the destroyers to sink us," said the officer.

"Not at all," replied the captain. "Unscrew the bolts of the door, Alfred. And now a word more, Mr. Officer. Where are your flags?"

"I refuse to inform you," said the officer, with a look of determination in his face.

"I expect a shot every minute," said the captain, "for I know as well as you do that there is a cruiser on our port side. I shall give you another opportunity; where are the flags?"

"You must open the hatch for them," said the officer.

"All the bolts are out," said Alfred, turning to the captain.
