A wireless was sent to the shore, reporting the failure of the Salvador to locate the runaway aËroplane and asking if any tidings had been received of Orissa Kane and Sybil Cumberford.

There was no news.

Madeline called her passengers together again for a further consultation.

"What shall we do?" she asked.

Neither Steve nor Mr. Cumberford could well reply. Miss Dentry had generously placed her splendid yacht at their disposal and in person had conducted the search, neglecting no detail that might contribute to their success. But failure had resulted and they could not ask her to continue what appeared to be a hopeless undertaking. Steve, who had had ample time to consider this finale, tried to answer her question.

"We are very grateful to you, Miss Dentry," he said, "and both Mr. Cumberford and I fully appreciate the sacrifice you have made in so promptly trying to rescue our girls. That we face failure is no fault of yours, nor of your crew, and I realize that you have already done all that humanity or friendship might require. Of course you understand that we cannot give up until my sister's fate, and that of Miss Cumberford, is positively determined. Therefore, as soon as we reach shore we shall organize another expedition to continue the quest."

"You are doing me an injustice, sir," returned the girl gravely. "Whatever my former plans may have been I am now determined not to abandon this voyage until we have found your sister and her companion. I was greatly attracted by Orissa Kane, and grieve over her sad fate sincerely. Moreover, I do not like to put my hand to the plow without completing the furrow. Unless you believe you can charter a better boat for your purpose than the Salvador, or can find a crew more devoted to your interests, I shall order Captain Krell to turn about and renew the search."

That, of course, settled the matter. The Salvador put about and returned to a point where the see-sawing must be renewed and extended to cover more expanse of ocean.

Chesty Todd, coming to where Madeline stood beside the rail, looked into her piquant face with frank admiration.

"Excuse me, Miss Dentry," said he, "but you're what I'd call a brick. I knew, of course, you'd stick it out, but there's no harm in congratulating a girl on being true blue. I'm awfully glad you—you had the grit to tackle it again. I'll never be myself again until those girls are found."

She looked up at him reflectively.

"Which of the young ladies are you engaged to?" she asked.

"Me?" blushing like a schoolboy; "neither one, if you please. They—they're only kids, you know."

"Then which one do you love?"

"Both!" said Chesty Todd, earnestly. "They're splendid girls, Miss Dentry; your sort, you know."

She smiled.

"Then it's the 'sort' you love?" she asked.

"Yes, if you'll allow me. Not the individual—as yet. When I love the individual I hope it'll be the right sort, but I'm so humbly unlucky I'll probably make a mistake."

For the first time since their acquaintance Madeline found the big boy interesting. She knew very little of the history of the Kanes and Cumberfords, but found Chesty eager to speak of them and of his past relations with them, being loud in his praise for the entire "combination." Cumberford was an eccentric fellow, according to Mr. Radley-Todd, but "straight as a die." Steve was chock full of ability and talent, but not very practical in business ways. Mrs. Kane, Orissa's blind mother, was the sweetest and gentlest lady in the world, Sybil Cumberford a delightful mystery that defied fathoming but constantly allured one to the attempt, while Orissa——

"Orissa Kane is a girl you'll have to read yourself, Miss Dentry, and the more you study her the better you'll love her. She's girl all over, and the kind of girl one always hopes to meet but seldom does. Old-fashioned in her gentleness, simplicity, truth and candor; up-to-the-minute in the world's latest discovery—the art of flying. Modest as Tennyson's dairymaid; brave as a trooper; a maid with a true maid's heart and a thorough sport when you give her an aËroplane to manage. Excuse me. I don't often talk this way; usually I can only express myself in writing. But a fellow who wouldn't enthuse over Orissa Kane could only have one excuse—total dumbness."

"I see," said Madeline, slyly. "Miss Kane is the type of the 'sort' of girl you love."

"Exactly. But tell me, since you've started on such an indefinite cruise, is the Salvador well provisioned?"

"From the sublime to the ridiculous! We have stores to last our party six weeks, without scrimping."

"Good. And coal?"

"Enough for a month's continuous run. I had intended a trip to Honolulu—perhaps as far as Japan—and had prepared for it even before I was privileged to lay eyes on my yacht."

"How fortunate that was, for all of us! Somehow, I've a feeling we shall find those girls, this time. Before, I had a sort of hunch we were destined to fail. Can you explain that?"

"I shall not try."

"We didn't allow enough for the wind. A sudden gust might have whirled the Aircraft in any direction, and it would jog along on that route until the next blow."

"Do you believe they are still alive?" she asked softly.

"Yes; I've never been able to think of them as—as—otherwise. They are wonderfully clever girls, and Orissa knows aËroplanes backwards and forwards. She's as much at home in the air as a bird; and why shouldn't the machine fall gently to the water, when the gasoline gave out? If it did, they can float any length of time, and the Pacific has been like a mill pond ever since they started. According to Mr. Cumberford, they have enough food with them to last for several days. I've an idea we shall run across them bobbing up and down on the water, as happy and contented as two babes in the wood." The big fellow sighed as he said this, and Madeline understood he was trying to encourage himself, as well as her.

In spite of Chesty Todd's prediction, day followed day in weary search and the lost aËroplane was not sighted. Captain and crew had now abandoned hope and performed their duties in a perfunctory way. Stephen Kane had grown thin and pale and deep lines of grief marked his boyish face. Mr. Cumberford was silent and stern. He paced the deck constantly but avoided conversation with Steve. Madeline, however, kept up bravely, and so did Chesty Todd. They were much together, these trying days, and did much to cheer one another's spirits. Had a vote been taken, on that tenth dreary day, none but these two would have declared in favor of prolonging what now appeared to be a hopeless quest.

"You see," said Chesty to Madeline, yet loud enough to be heard by both Cumberford and Steve, "there's every chance of the girls having drifted to some island, where of course they'd find food in plenty; or they may have been picked up by some ship on a long voyage, and we'll hear of 'em from some foreign port. There are lots of ways, even on this trackless waste, of their being rescued."

This suggestion was made to counteract the grim certainty that the castaways had by now succumbed to starvation, if they still remained afloat. Several small islands had already been encountered and closely scanned, with the idea that the girls might have sought refuge on one of them. The main thing that kept alive the spark of hope was the fact that no vestige of the Aircraft had been seen. It would float indefinitely, whether wrecked or not, for the boat had enough air-tight compartments to sustain it even in a high sea.

On the evening of this tenth day the Salvador experienced the first rough weather of the trip. The day had been sultry and oppressive and toward sundown the sky suddenly darkened and a stiff breeze caught them. By midnight it was blowing a hurricane and even the sturdy captain began to have fears for the safety of the yacht.

There was little danger to the stout craft from wind or waves, but the sea in this neighborhood was treacherous and full of those rocky islets so much dreaded by mariners. Captain Krell studied his chart constantly and kept a sharp lookout ahead; but in such a night, on a practically unknown sea, there was bound to be a certain degree of peril.

There was as little sleep for the passengers as for the crew on this eventful night. The women had been warned not to venture on deck, where it was dangerous even for the men; but Madeline Dentry would not stay below. She seemed to delight in defying the rage of the elements. Clinging to the arm of Chesty Todd, the huge bulk of whose six-feet-three stood solid as a monument, she peered through the night and followed the glare of the searchlight, now doubly useful, for it showed the pilot a clear sea ahead.

Mr. Tupper bumped into them, embraced Chesty for support and then bounded to the rail, to which he clung desperately.

"Why are you on deck?" asked Madeline, sternly. "Go below at once!"

Just then a roll of the yacht slid him across the deck, tumbled him against the poop and then carried him sprawling into the scuppers. When he recovered his breath Mr. Tupper crawled cautiously to the companionway and disappeared into the cabin.

Steve and Mr. Cumberford had lashed themselves to the rail and in spite of the drenching spray continued to peer into the wild night with fearful intensity. Both were sick at heart, for they knew if the girls had managed to survive till now, their tiny boat would be unable to weather the storm. Every shriek of the wind, which often resembled a human cry, set them shivering with terror.

It was toward morning when the glare of the searchlight suddenly revealed a dark peak just ahead. Stephen Kane and Mr. Cumberford saw it, even as the warning scream of the lookout rang in their ears. Captain Krell saw it, and marveling at its nearness, sprang to the wheel. Madeline and Chesty saw it, too, and instinctively the big fellow put his arms around her as if to shield her.

Wild cries resounded from the deck; the bells rang frantically; the engines stopped short and then reversed just as a huge wave came from behind, caught the Salvador on its crest and swept her forward in its onward rush. Two men threw their weight upon the wheel without effect: the propeller was raised by the wave above the water line and whirred and raced madly in the air, while beneath the gleam of the searchlight a monstrous mass of rock seemed swiftly advancing to meet the fated ship.

Past the port side, where Madeline and her escort clung, swept a jagged point of rock; the yacht bumped with a force that sent everyone aboard reeling forward in a struggling heap; then it trembled, moaned despairingly and lay still, while the wave that had carried it to its doom flooded the decks with tons of water and receded to gloat over the mischief it had caused.

The searchlight was out; blackness surrounded the bruised and bewildered men and women who struggled to regain their feet, while in their ears echoed a chorus of terrifying shrieks not of the wind, but so evidently emanating from living creatures that they added materially to the panic of the moment.

Chesty Todd released Madeline, gasping and half drowned, from the tangle of humanity in the bow, and succeeded in getting her to the rail. The bow of the yacht was high and it lay over on one side, so that the deck was at a difficult angle.

"Are—are we sinking?" asked the girl, confused and unnerved by the calamity.

"No, indeed," replied Chesty, his mouth to her ear. "We can't sink, now, for we're on solid ground and lying as still as a stuffed giraffe."

"Oh, what shall we do?" she cried, wringing her hands. "If we are wrecked we can't save Orissa—perhaps we can't save ourselves! Oh, what shall we do?—what shall we do?"

The boy saw that the shock had destroyed her usual poise and he could feel her trembling as she clung to him.

"My advice," he said quietly, "is that we all get to bed and have a wink of sleep. It has been a long and exciting day for us, hasn't it?"
