or Ah Sing, and when at length the affrighted Celestial
appeared at the top of the ladder, Bob sent him for some stimulant. Ah
Sing vanished, and a cry of joy broke from Bob's lips, as he saw a faint
color come into Mart's face and ebb out again. Mart was alive!

Bob labored furiously, and when Ah Sing showed up with a bottle of
alcohol, he said nothing but rubbed Mart's face and neck with the fiery
liquid. Presently he was rewarded by a twitch of Mart's eyelids, a
little more color came into the faded cheeks, and then the gray eyes
opened and looked up into his.

"Look out--he's coming!" whispered Mart, his hand going up and clutching
Bob's arm.

"It's all right, old boy," cried Bob, tears running down his cheeks with
the relief that gripped him. "You're safe--take it easy!"

Up above them, Ah Sing burst into a frenzied chattering, then rushed
away, but neither boy noticed him. Mart lay motionless, looking up into
Bob's eyes and slowly feeling strength come back to him as the reviving

CHAPTER XVII

THE MYSTERY O' THE SEA

As around the stern of the _Seamew_ came a prau, Ah Sing shrieked aloud
in delight and the boys gave a hearty cheer at sight of Captain
Hollinger and Swanson standing in the prow of the craft. Beside them
stood the two engineers, while the Kanaka crew of the yacht were at the
sweeps.

"By golly, they got away!" gasped Mart, managing to scramble to his
feet. The sight of the motionless figure of Jerry Smith sobered both
boys, however, and while Bob stepped forward to meet his father, Mart
kneeled down beside Jerry with feeble efforts to revive him. His own
strength was not yet fully returned.

"What's all this?" demanded the captain, as he leaped from the prau to
the landing. "Where are those mutineers, Bob?"

"Ashore, all but Jerry," returned Bob promptly, pointing to the
quartermaster's figure. Captain Hollinger waved bac
