"And there was an American sailor with him," insisted Frank.

"Yes, an, American sailor who evidently knew too much. At least, that is the way I figure it out. Now, we are not looking for this high-brow at this time, but for the American sailor."

"That makes it all the pleasanter!" Jack said. "We'll have a chance to see life in Japan as it is. I'd feel better about this little outing, though, if I knew just what has become of Lieutenant Rowe."

"I often wish we had tried to release him," Ned replied, "but we were lucky to get off with whole hides. Anyway, Pat says they were to release him in a short time, after the plot is perfected. All they wanted was his dispatches, and they will hold him captive only because his release might lead to the premature discovery of the meeting of chiefs on the island."

"Well, let us get busy with the underworld of Japan," Jack said. "I'll bet we find plenty of American sailors with thirsts."

On a dark night in Yokohama the houses in the section visited by the boys look very much alike. They are drygoods box affairs, two stories high, with peaked roofs, paper walls and narrow piazzas. All the shops are looking for the American sailor.

Ned secured an interpreter, and the boys strolled through a dozen or more cheap joints before they came to a halt and sat down. The places were all alike. There was split matting on the floors, always, and sailors drinking at little tables. There was always a fair grade of tea, always sake, always a wheezy graphophone.

One might also buy whiskey, ale and other intoxicating drinks. And there were also the geisha dances and the nesans running up stairs and down with their little white socks and flowery skirts, carrying refreshments. There were also men in kimonos and cowboy hats, the former to give the Japanese color and the latter to inform customers that the American trade was catered to!

"How you goin' to know this American sailor when you find him?" asked Jimmie, as the boys sat with steaming cups of tea before them.

"I have his photograph," laughed Ned.
