The sun was going down into the Gulf of Tong King like a ball of red fire, and the night was far from cool.

Jimmie declared he could hear the water hiss as the sun dipped its red rim under the waves. The boy now stood by Ned's side, looking over the wonderful scene.

"We've been somewhere near here before," he said. "You remember the time we came over to this side of the world and found a key to a treaty box? Well, we wasn't far from this spot at one time."

"Right you are," Frank replied. "Only we hope to find something more important than a key now. I hope they've had use for a cell key in connection with that mix-up at Mare Island Navy Yard."

"It was rotten to let that fellow get away!" Jimmie declared. "I just knew they would."

"We were all so astonished at the recovery of Lieutenant Scott," Ned observed, "that we overlooked a few things we ought to have kept in mind. Wasn't it glorious! Think of Scott coming out of it all right at last!"

"Well, he said he was a fixture on the coast until he found the man who came so near killing him," Frank said, in a moment, "and I hope he'll make good."

"Huh," Jimmie interrupted, "if you think that fellow is on the Pacific coast yet, you've got another think comin'. You remember the Diver left San Francisco just about the time we did."

"What has that to do with it?"

"Most nothin' at all, only he sailed in her."
