"Are Banks and Moy safe?" gasped the young officer.

"Safe? Of course they are," replied Lieutenant Watterley, giving a hasty glance over the side to where two distinct clusters of air-bubbles marked the progress of the divers. "What have you seen? But no, say nothing more at present. Wait till you're out of your dress, and you can report to the captain."

Arnold Hythe sat down on a bollard and attempted to collect his scattered thoughts, while his attendant proceeded to remove his helmet and leaden weights. Ere his india-rubber dress was stripped off Banks and Moy appeared over the side.

"Well?" demanded the first lieutenant laconically.

"Nothin' to report, sir," replied Banks, while his companion signified corroboration by a nod of his head.

Mr. Watterley looked inquiringly at the sub. The flush upon his face had vanished and his features were white with excitement. Several of the officers had come up and were engaged in plying Hythe with questions, to which the latter paid no attention. He was still in a kind of stupor, the result of a sudden shock to his nerves.

"Now then, Mr. Hythe--why, what's the matter with you? Here, I must send for the staff-surgeon; I must, by George!"

Assisted by two of his brother officers the sub was taken below, and in a very short space of time Doctor Hamworthy succeeded in bringing him to a more normal state.

Meanwhile Admiral Hobbes, hardly able to conceal his impatience beneath a cloak of official reserve, was engaged in animated conversation with Captain Warborough upon the eventful incidents that had necessitated the return of the Fleet to Spithead.

"Commander-in-Chief coming off, sir!" reported the lieutenant of the watch.
