As they sat with downcast countenances, reflecting upon their uncomfortable position, Orissa said quietly:

"I've thought of something to relieve us. The idea came to me when Chesty insisted our launch could run the blockade."

"Speak out, Ris," exclaimed Steve. "Your ideas are pretty good ones, as a rule. What's the proposition?"

"Why, we all seem to have forgotten the Hy."

"The Hydro-Aircraft?"

"Yes. It is lying quite safe, and in apple-pie order, in the little ravine at the foot of the bluff where we camped."

"But it is minus its plane-cloths," added Sybil. "Our tent is still standing, for I saw it from deck only an hour ago."

"It won't take long to attach the plane-cloths," said Steve, "provided those brigands will let us do it. It's rather odd they haven't taken the trouble to capture the Aircraft already. It would be easy for Ramon to declare it 'wreck.'"

"What would be the use?" asked Madeline. "They could not fly it, even if they knew how to put it in order; and, as they imagine we cannot get to it, they are not worrying about the thing. Of course they are able to see that tent on the bluff as easily as we can, and by and by they will go there and capture whatever the girls left."

"True. That is why we must lose no unnecessary time," observed Orissa.

"I do not yet see what the proposition is," asserted Chesty, in a puzzled tone.

"I know what Orissa means," returned Steve quickly. "There's plenty of gasoline on board—I think nearly a barrel—intended for the use of the launch. If I could get to the Aircraft and fill its tanks with gasoline no one could prevent my flying home, where I could get a ship and men to come to our rescue."

"That interests me; it does, really!" said Mr. Cumberford. "It's so easy and practical I wonder none of us thought of it before."

"I've had the possibilities in mind for some time," declared Orissa, "but I had no idea we could get to the Aircraft until Chesty proposed running the blockade in our launch."

"It's a fine idea," said Chesty, with enthusiasm. "I mean both our ideas—the combination, Orissa."

"I believe it will solve all our difficulties," added Madeline, confidently. "But will not this journey be a hazardous one for Mr. Kane to undertake?"

"I think not," replied Orissa. "The same amount of gasoline that brought Sybil and me to this place will carry the machine back again, and Steve can go more directly than we came, for he knows exactly how to head."

"Then!" said Chesty Todd, "the plan is this: We'll put enough gasoline in cans to fill the tanks of the aËroplane, load 'em into the launch, and to-night Steve and I will sneak out of this inlet, slip past the Mexican's launch and hie us to that ravine of yours. Is there room enough for our boat to enter the bay you described, or is that big rock too close to shore to let us pass?"

"There will be just about room for you to pass in, I think," answered Orissa.

"But the big launch couldn't do it?"

"Ramon's? No, indeed."

"Very good."

"Who will fly with me to San Diego?" asked Steve. "The Aircraft carries two, you know. One of the women ought to go. I wish we could carry them all away from this dangerous place."

"Let them draw cuts for it," suggested Chesty.

"You can let me out," said Sybil; "I won't leave Daddy."

"Nonsense!" cried her father.

"Then I'm nonsensical," laughed Sybil, "for I won't budge an inch without you. That wicked Mexican might capture you in a jiffy if I wasn't here to look after you. Not a word, sir; the thing is settled, as far as I am concerned."

"I cannot go, of course," said Madeline. "This is my yacht and I must stand by it, and by my men, to the last. Nor could I with courtesy escape and leave my guests in danger."

"Then it shall be Mrs. Tupper," proposed Orissa.

"Me? Me? Goodness sakes, child," cried Mrs. Tupper, in great alarm, "do you think I'd risk my life in that dreadful airship?"

"You'll risk it by staying," suggested her husband.

"But there's a chance of salvation here," asserted the lady, with nervous haste. "I'd get light-headed and tumble out of that aËroplane in two minutes. And they'd hear me yell from Japan to San Francisco, I'd be so scared. I can stand death, Mr. Tupper, with Christian fortitude; but not torture!"

"Orissa?" said Steve, inquiringly.

"Yes; I'll go. I may be of more assistance to you all by going than by staying. And I will run the machine, Steve, and take you as a passenger. I've tinkered that steering-gear until I know just how to manage it."

Steve nodded.

"As I understand it, Miss Dentry," said he, "my mission will be to charter a fast steamship, for which Mr. Cumberford and I will pay, and bring it here to drag the Salvador off this beach. The crew, which I will see is well armed, will work in conjunction with yours and when we outnumber Ramon Ganza's band of rascals he will probably run away to his den without attempting to fight."

"Ramon never run," protested Pietro, shaking his head. "You cannot scare Ramon. The more men you bring, the more he has to fight; that is all."

This gloomy prophecy made them look grave for a time.

"Our Pietro is a pessimist," said Chesty, with assumed cheerfulness. "But some day the Mexican government will find this invincible hero and send a warship to blow his island out of the water."

"Why—yes!" exclaimed Madeline, with sudden inspiration; "the Mexican government is interested in this affair. Why not fly to the nearest point on the Mexican coast, Mr. Kane, and from there telegraph President Madero? I believe he would send a warship at once, both to capture Ramon Ganza and to rescue us from his clutches."

"Um-m. Madero has his hands full, just now, putting down revolutions at home," Mr. Cumberford reminded her. "And maybe he isn't interested in Ganza, who was convicted of a felony under the rÉgime of Diaz."

"I can try him, anyhow," said Steve. "The Mexican coast is about fifty miles nearer than San Diego."

"Madero has offer one thousan' dollar—Mexican—for capture of Ramon," said Pietro, proudly. "So much money shows Ramon is great man."

"In that case you'd better give Madero a chance at him, Steve," decided Mr. Cumberford. "A man-o'-war would be more effective here than a trading ship, and in the interests of humanity we should put an end to this fellow's cruel tyranny for good and all. He's far better off in jail."

After some further discussion this plan was finally decided on and preparations were begun for the adventure. During the afternoon the cans of gasoline were placed in the launch and Steve went over the machinery of the little boat with great care, to assure himself it was in perfect order.

The nights were never really dark until toward morning, when the stars seemed to dim and the moon dipped below the horizon. Sometimes there were a few drifting clouds, but they never obscured the sky long enough to be utilized as a mask. So Steve decided to make his attempt at the dark hour preceding dawn and made Orissa go to bed and get what sleep she could. She said her good-byes to the others then, so it would not be necessary to disturb them at the time of departure.

At three o'clock her brother called her and told her to get ready. Chesty and Steve were seated in the launch when the girl arrived on deck, and she quickly took her place. While it was much darker than it had been earlier in the night, Orissa found she could see near-by objects quite distinctly. Four of the crew, headed by Captain Krell, were standing by to lower the launch over the side, and as the owls were hooting their most dismal chorus their screams drowned any noise made by the windlass.

No sooner had the launch touched the surface than Chesty dipped his scull in the water and with a dexterous motion sent the little craft forward toward the mouth of the inlet. They might have been seen from the shore had the Mexicans been alert, but at this hour many who were supposed to be watching had fallen asleep, and if any remained awake their eyes were not turned upon the waters of the tiny bay. Quite noiselessly the launch moved on and presently turned the point of rock at the right.

Orissa stifled a cry and Steve's heart gave a bound as the bow of the launch pointed straight at the big boat of Ramon, scarcely ten feet distant; but Chesty saw the danger, too, and a sharp swing of the scull sent the light craft spinning around so that it just grazed the side of the Mexican's boat, in which all the occupants were fast asleep.

Next moment they had passed it, and still Chesty continued sculling, as it was not safe as yet to start the engines. But when they had skirted the shore for such a distance that the screeching of the owls would be likely to drown the noise of their motor, Steve started the machinery and the launch darted away at full speed.

Half an hour later they crept between the big rock and the bluff and were safe in the deep hollow at the foot of the ravine, having accomplished the adventure so easily that they marvelled at their own success.

"Strikes me as a good omen," remarked Orissa, cheerfully, as they disembarked and drew the launch upon the sands. "I hope the luck will follow you on your return, Chesty."

"Me?" replied the big boy. "Why, nothing ever happens to me. Let us hope the good luck will follow you and Steve, on whom the safety of the entire party now depends. What first, Steve?

"The tent. We must get that down before daybreak, so they won't see us working on it from the bay, and interfere with our proposed flight."

Orissa led the way to the bluff and at once Steve and Chesty began tumbling the rocks from the edges of the canvas. This was no light task, for the girls had erected a solid parapet in order to defy the wind; but just as the first streaks of dawn appeared the tent came down and they hastily seized the canvas, added it to the covering of the upper plane, which had been inside the tent, and lugged it all down the incline to where the frame of the Aircraft lay.

"Very good," said Steve. "We'll need the daylight now, in order to attach the cloth."

They had not long to wait, and while Steve, assisted by Radley-Todd, fastened the cloth in place with the clips provided for that purpose, which Orissa had carefully saved, the girl herself inspected the machinery and all the framework, even to the last brace, to be sure it was in condition for the long trip. She also oiled the steering gear and thoroughly tested it to see that it worked freely.

By nine o'clock the planes were tautly spread and the tanks had been filled with gasoline.

"I think we are all ready for the start," said Steve. "But how about you, Chesty? As soon as we roll the Aircraft to the top of the bluff the Mexicans will see us and start for this place to try to intercept us. Orissa and I will be gone, when they arrive; but they may find you, unless you make tracks."

"How do you expect to regain the ship?" asked Orissa, who had not considered this matter before.

"Don't worry about me, I beg of you," retorted the boy, hastily. "I shall be all right. All ready, Steve?"

Steve looked at him thoughtfully.

"I think that when they see us fly away they may give up the idea of coming here," said he; "and, in that case, you'd better lie here in the ravine until night, when you can try to steal back in the same way we came."

"All right, old man; never mind me."

"But we do mind you, Chesty," said Orissa, earnestly. "You've been a faithful friend ever since we got into this difficulty—and before, too—so we can't have anything happen to you."

He blushed like a girl, but declared he would be perfectly safe.

"Don't take any foolish chances," urged Orissa.

"I won't."

They rolled the Aircraft up to the top of the bluff and set it with the head facing the sea. Then Steve and Orissa took their places and Chesty, giving them each a hearty handclasp, spun the propeller blade as Steve started the engine.

At once the aËroplane darted forward, rose as it passed the bluff, and sailed gracefully into the air. Chesty hid his six-feet-three behind a boulder, to shield himself from observation, while he watched the splendid machine turn upon its course and speed away over the Pacific on its errand of rescue.

Then, with a sigh of relief and elation, the boy crept into the ravine and descended to where his boat lay. Seated in the launch, calmly awaiting him, were three of the Mexicans, headed by the one-eyed Francisco.
