With an effort the Prime Minister seemed to gather himself together. He found the pace a little breathless, even for him.

"I think it might be arranged, Grayne," he said tactfully. "Mr. Dene knows his own invention and we might enrol his crew in the Navy; what do you think?" Mr. Llewellyn John abounded in tact.

"I take it that you understand navigation, Mr. Dene?" ventured the Admiral.

"Sure," was the reply. "You come a trip with me, and I'll show you navigation that'll make your hair stand on end. Sorry," he added a moment after, observing that Admiral Heyworth was almost aggressively bald.

"That's all right," laughed the Admiral; "they call me the coot."

"Well, is it a deal?" demanded John Dene, rising.

"It is," said Mr. Llewellyn John, "and a splendid deal for the British Empire, Mr. Dene," he added, holding out his hand. "It's a great privilege to meet a patriot such as you. Sir Lyster and Admiral Heyworth will settle all details to your entire satisfaction."

"If they do for me, I want you to give the command to Blake, then to Quinton, and so on, only to my own boys; is that agreed?"

"Do for you?" queried Mr. Llewellyn John.

"Huns, they're after me every hour of the day. There was a little chap even in your own building."
