Consternation reigned in the cabin when the principals assembled there with white and startled faces. On deck Captain Krell was instructing his men how to act in the threatened emergency. Pietro was among them, accepting his rifle and his instructions willingly, but shaking his head at what he considered a vain attempt to resist Ramon Ganza.

"Ramon great man!" he said to Captain Krell. "Ramon always win; nobody can conquer him. I knew Ramon would win this time, an' when he does he will capture me an' whip me hard. All right; I know I am to be whipped at the time Chica tell me to leave Ramon. Never min'. Pietro can stand it, for others have been whipped by Ramon an' lived—with marks like a zebra's on their skins."

In the cabin Chesty was trying to explain the situation.

"It's this way," he said; "when the rocks are all removed the yacht will fall over on her side, as she was at first, with the rail quite near to the water. You remember how she lay before we propped her up. Well, that means we have no secure footing on deck and that the pirates can easily climb aboard and have the best of the argument. If we slip, we fall into their arms; if we stick to the deck—like flies to a ceiling, they'll rush and get us."

"We can't fight from the deck," declared Cumberford. "Tell Captain Krell to come here."

The captain arrived and after a consultation it was decided to gather all hands in the cabin and fortify it as strongly as possible. The roof projected a few feet above the deck and there was a row of small windows on either side, but these were supplied with heavy shutters designed for use in case of storms, when the shutters were readily fixed in place. The stairway might be well guarded by one man, and above the windows were small ventilators through which several rifles could be pointed. By standing upon the cabin table the defenders could command the deck in this way. They were instructed not to shoot, however, unless absolutely obliged to. All the hatches were battened down, so that if Ganza gained the deck he could not get below and was welcome to remain aboard until the rescuers arrived.

Orissa, who had listened silently, now approached Mr. Cumberford and said:

"When the yacht tips, our Aircraft will be ruined, for the chances are it will slide overboard. Even if it doesn't, those scoundrels will wreck it completely, for it will be quite at their mercy. So I've decided, while there is yet time, to fly it across to the bluff, where I can remain until you are rescued."

"Can you manage to get away from the deck?"

"Easily."

"Then I think it best for you to go."

"May I take Sybil with me?"

He hesitated a moment; then replied: "Yes. It will be a good thing to have you girls away from here when the attack is made. Here you could be of no service whatever, and your absence will—eh—give us more room to defend the cabin."

"You will have to act quickly, Miss Kane," suggested Chesty.

"I know. Come, Sybil."

They drew on their jackets as they went on deck, both girls realizing that no time must be lost if they hoped to get away. Once the yacht tipped on her side it would be impossible to fly the machine.

As they took their places Mr. Radley-Todd inquired: "Plenty of gasoline?"

"I think so," said Orissa. "I'm not sure how much is left in the tanks, but it ought to be enough to get us to the bluff. Whirl the propeller, Chesty."

He did so, and the engine started with a roar. Cumberford and Chesty steadied the Aircraft until the motor had acquired full speed and then Orissa threw in the clutch and the big aËroplane rose as easily as a bird takes flight and ascended into the starlit sky at a steep angle. This feat is what is called "cloud climbing" and Orissa understood it perfectly.

It seemed a bold thing to undertake such a flight in the nighttime, but the Flying Girl's friends had so much confidence in her skill that they never considered the danger of the undertaking. Across the barren island to the bluff was so unimportant a flight to one of Orissa's experience that when she was once away they believed her quite safe.

While the men stood watching the Aircraft mount into the dim sky the yacht suddenly trembled and keeled over, throwing them all flat upon the deck. With one accord they scrambled up and dashed into the cabin, which they reached just as Ramon Ganza and his men swarmed over the rail.
