Tringanu!"

Five minutes later Mart Judson found himself at a big mahogany table,
his chum opposite him, while the captain got charts from another cabin.
The luxury about him was astonishing; mahogany furnishings, walls,
bookcases, a talking machine and a piano, electric lights and fans.
Everything that could add to comfort or convenience was there, and he
was soon to find that the rest of the yacht was fitted up in like
manner.

"Now," began Captain Hollinger, returning with his maps and charts,
"maybe you know, Mart, that I'm something of a big game hunter, eh?"

"I should guess!" grinned Mart. Like everyone else in San Francisco he
knew that Stephen Hollinger was an enthusiastic sportsman; indeed,
mining and hunting were said to be his chief pleasures in life.

"Well, I'm going hunting. And I'm going here--" he put his finger on the
map as the two boys craned their necks over it. "Tringanu is one of the
Malay states, on the mainland of Asia; it's not exactly civilized, but
I'm thinking of getting a mining concession there at a place I heard of.

"Here it is, on this chart of the China Sea. About halfway up the coast

could use a wireless man--had to have one, in fact--and he said you had
your license."

"Got it two weeks ago," admitted Mart with some pride. It had cost him
many hours of nightwork and study, had that license as wireless
operator. Then his face fell suddenly. "I'm not old enough to take the
job, though--"

"Shucks, that don't matter!" broke in Holly. "This isn't a reg'lar job."

"No," assented his father. "All you would have to do is to get market
reports every few days and send some messages back. Look at these maps
again, boys. Now, here's the place, I figure that we'll go to Honolulu,
then hit straight for our goal. The river is named Kuala Besut, and
we'll probably stay there a couple of weeks or more, using divers. All
the gold along there has to be dredged up, y
