“Ah, vat luck!” wailed Carl. “Ve come afder vone Amerigan consul und lose anodder!”

Bob, carefully watching the periscope as he talked, repeated the experiences that had overtaken him and Dick while they were reconnoitering to find some trace of Jordan’s party.

The presence of Ysabel had aroused much curiosity in all of them, and the explanation as to how she came to be on the boat straightened out that part of the matter to the satisfaction of every one. Carl, in particular, was highly pleased. He had dried himself out, after his fall in the river, and was feeling easy in his mind, now that Bob and Dick, at least, had been kept out of the hands of General Pitou.

“You did a big t’ing, Miss Sixdy,” said Carl, “ven you safed Bob und Dick, und Bob did more ven he safed you, so dot vas efen. Now, if ve don’d make some misdakes in our galgulations und are aple to resgue dot boat loadt of brisoners, eferypody vill be so habby as I can’d dell. Of gourse, I’m not in it, at all. I haf to shday behindt und dake care of der supmarine.”

“Do you feel pretty sure, Bob,” queried Gaines, “that the motor launch with the prisoners will come down the Izaral?”

“All we have to go on, Gaines, is Coleman’s note,” answered Bob. “I may say that this move constitutes our only hope. If something doesn’t happen, about as we expect and hope it will, then we’ll have to give up all thought of doing anything for Coleman, or our friends.”

“We’ll hope something will happen, mate,” said Dick. “In case the launch comes down the river, what are you intending to do?”

“I have my plans, Dick,” said Bob. “If every one carries out his orders on the jump, I feel pretty sure the plan will carry. The main thing is to keep a keen watch for the launch.”

“That’s easy enough during daylight, with the periscope ball elevated as it is,” remarked Gaines, “but if the launch happens to come downstream in the night—which, it strikes me, is altogether likely—then the boat is apt to get past us.”

“Not if a good lookout is kept.”
