"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.
