Byrne was on his feet now.  He found his sword and revolver and replaced them in his belt.

“You men stay here on the island and take care of Miss Harding,” he said.  “If I don’t come back the marines will find you sooner or later, or you can make your way to the coast, and work around toward the cove.  Good-bye, Miss Harding.”

“Where are you going?” cried the girl.

“To get your father—­and Mr. Mallory,” said the mucker.

CHAPTER XVI

THE SUPREME SACRIFICE

Through the balance of the day and all during the long night Billy Byrne swung along his lonely way, retracing the familiar steps of the journey that had brought Barbara Harding and himself to the little island in the turbulent river.

Just before dawn he came to the edge of the clearing behind the dwelling of the late Oda Yorimoto.  Somewhere within the silent village he was sure that the two prisoners lay.

During the long march he had thrashed over again and again all that the success of his rash venture would mean to him.  Of all those who might conceivably stand between him and the woman he loved—­the woman who had just acknowledged that she loved him—­these two men were the most to be feared.

Billy Byrne did not for a moment believe that Anthony Harding would look with favor upon the Grand Avenue mucker as a prospective son-in-law.  And then there was Mallory!  He was sure that Barbara had loved this man, and now should he be restored to her as from the grave there seemed little doubt but that the old love would be aroused in the girl’s breast.  The truth of the matter was that Billy Byrne could not conceive the truth of the testimony of his own ears—­even now he scarce dared believe that the wonderful Miss Harding loved him—­him, the despised mucker!

But the depth of the man’s love for the girl, and the genuineness of his new-found character were proven beyond question by the relentless severity with which he put away every thought of himself and the consequences to him in the matter he had undertaken.

For her sake! had become his slogan.  What though the results sent him to a savage death, or to a life of lonely misery, or to the arms of his beloved!  In the face of duty the result was all the same to Billy Byrne.

For a moment he stood looking at the moon-bathed village, listening for any sign of wakefulness or life, then with all the stealth of an Indian, and with the trained wariness of the thief that he had been, the mucker slunk noiselessly across the clearing to the shadows of the nearest hut.

He listened beneath the window through which he and Barbara and Theriere had made their escape a few weeks before.  There was no sound from within.  Cautiously he raised himself to the sill, and a moment later dropped into the inky darkness of the interior.
