loudly for Fritz and Jack.

"It is not very respectfull, captain, to handle you in this way; but
the case is urgent, and I should like to have the mystery cleared up."

The two brothers, when they entered the cabin, beheld Willis holding
the captain tightly in his arms.

"I have caught him at last, you see," said the Pilot.

"So it would appear," observed Jack; "but are you not aware the
captain is asleep?"

And so it was Littlestone had walked from his own cabin to that of
Willis in a state of somnambulism.

"What is the matter?" inquired the latter, when he became conscious of
his position.

"Nothing is the matter, captain," replied Jack, "only you have been
walking in your sleep."

"Ah--yes--it must be so!" exclaimed Littlestone; gazing about him with
a troubled air. "Have I not paid you a visit of this kind before,
Willis?"

"Yes, often."

"Where?"

"On board the _Boudeuse_."

"That must have been the craft I was transferred to, then, after the
capture of the _Nelson_. Just call Mr. Wolston, and let us have the
matter explained."

On comparing notes, it appeared that the captain and the missionary
had been on board the _Boudeuse_. Both had been ill, and both had been
closely confined to their cabin during the entire voyage, partly on
account of their being prisoners of war, and partly on account of
their illness. On one occasion, but on one only, the captain had
escaped from his cabin during the night. Willis might, therefore, have
seen him once, but that he had seen him oftener was only a dream.

"It appears, then," said Littlestone, "that my illness has left this
unfortunate tendency to sleep-walking. I shall, therefore, place
myself in your hands, Master Jack; perhaps you may be able to chase it
away."

"I will do my best, captain; and I think I may venture to promise a
cure."

Willis was sorry for the captain's sleeplessness, but he was glad that
the mystery hanging over them both had been so far cleared up. His
visions and dreams had been a source of constant annoyance to him; but
now that their origin had been discovered, he felt that henceforward
he might sleep in peace.

After a rapid run, the sloop cast anchor off the Cape. Here Captain
Littlestone reported himself to the commander on the station, and
received fresh papers. He also sent off a despatch to the Lords of the
Admiralty, in which he reported the capture and rescue of his ship. He
informed them that his own escape and tha
