The signal officer was very polite, and fortunately understood a little English. So Frank managed, with the aid of the book, to make him understand his questions. No craft at all answering to the description had been noticed passing during the last five or six days; certainly no yacht had passed. She might, of course, have gone by after dark.

He showed Frank the record of the ships that had been sighted going east, and of those that had made their numbers as they passed. The Phantom was not among the latter, nor did the rig or approximate tonnage, as guessed, of any of the others, at all correspond with hers.

After thanking the officer, Frank returned to his boat, and half an hour later the Osprey was again under weigh.

At Ceuta, Tarifa, and Tangier there was a similar want of success. Such a craft might have passed, but if so she was either too far away to be noted, or had passed during the night. From Tangier he crossed to Gibraltar, and anchored among the shipping there.

So far everything had gone to confirm his theory that the Phantom would not go up the Mediterranean. Of course, she might have passed the three places, as well as Saint Vincent, at night; or have kept so nearly in the middle of the Strait as to pass without being remarked. Still, the chances were against it, and he regarded it as almost certain that she would have put into one or other of the African ports, as she passed them, for water, fresh meat and fruit.

It was six days after the Osprey passed Saint Vincent before she anchored off Gib. She had made her number as she came in, and in a short time the health officer came out in a boat. The visit was a formal one; the white ensign on her taffrail was in itself sufficient to show her character, and that she must have come straight from England; and the questions asked were few and brief.

"We are ten days out," Frank said. "We have touched at Tarifa, Ceuta, and Tangier, but that is all. The crew are all in good health. Here is the list of them if you wish to examine them."

"As a matter of formality it is better that it should be done," the health officer said.

"I will order them to muster," Frank said, "and while they are doing so, will you come below and take a glass of wine?

"Can you tell me if a craft about this size, a schooner or brigantine, has put in here during the last fortnight? I don't know whether she is still flying yacht colours, or has gone into trade, but at any rate you could see at once that she had been a yacht."
