hed softly, gazing out at the sparkling waters.

"The Kanakas ain't afraid, lad. Only they don't know--they don't know.
You see, this here Pirate Shark is pretty famous down through the Chiny
Sea. But old Jerry Smith, he's the only one that knows. He's the only
white man, lads. The Chinks know, and the Malays know, but they wouldn't
go near the place. The mystery o' the sea, lads--wave after wave! The
gold down below, and us up above--and fish tell no tales, lads--"

He fell silent, still gazing at the horizon. Mart glanced at Bob, and
caught a significant wink as Holly tapped his forehead. Mart frowned.

"What do you mean?" he asked sharply. "Is there a shark by that name?
What kind o' stuff are you handing us, Jerry?"

The old man turned and looked square at him, and his gentle face seemed
suddenly changed into a swift vehemence that was amazing. But it
vanished instantly, and he was himself again--as if he had put on a
mask, thought Mart quickly.

"The Pirate Shark," answered old Jerry slowly. "Yes, I'll tell you about
it, lads. There ain't many as knows where the Pirate Shark is, but old
Jerry Smith, he knows. He's a big shark, he is--mighty big, an' a

half a dozen Jap pearlers. Then he showed up in the Flores Sea, an' for
a year the fishers didn't dare visit the pearlin' beds. After that he
went over to the Sulu Islands, down to Java, back to the Chiny
Sea--always killin' men, natives or white. Then he vanished for a

Again the old man paused, dreaminess on his gentle face. The boys were
leaning forward eagerly, and Bob brought him back abruptly to the
subject.

"But what about this place we're goin' to? Is he there now?"

Once more that peculiar look flitted across the wrinkled face--a look of
swift suspicion, that vanished as quickly as it came. Jerry smiled
softly.

"Why, yes! See here, lads, you promise you'll say nothing? I likes you
fine, but I don't want news leakin' out. I'm an old man--fish tell no
tales, lads--"

"Of course," agreed Mart instantly. "We'll keep quiet, Jerry." Bob
nodded.

"Well, this is a yarn as a Chink told me, lads. But it's true, gospel
true! A long time ago there was only Portugees an' Dutch in the Chiny
sea, an' they carried on somethin' awful, fightin' an' robbin'. Once
there was a big battle--"

"Yes!" volunteered Bob eagerly. "I was readin' abou
