"I'm tired of bothering with these Sons of the Rising Sun," Matt answered. "We never know what they're going to do, or when they're going to do it. I thought we had dropped them for good, down below English Reach, but they were clever enough to get away from Sandoval and play that trick in Lota. If possible, let's put them out of the running, now, for keeps."

"How will you do it?" questioned Gaines.

"I'm not just sure of that, and won't be until I do a little reconnoitring ashore. I've a scheme in mind, but I want to be positive it will work before we try it. Go down to the engine room, Gaines, and, Clackett, you take your usual place in the tank room. Heave up the anchor, Speake. Glennie, you get into the conning tower. If the current sets inshore and causes the Grampus to drift that way when the anchor is up, have the motor run just enough to hold the boat where she is. Dick, you hang on to the rifle. When you go down, Gaines, pass up the strongest cable we have, so that Carl can bend it on to the mooring ring at the stern. Understand?"

"I guess we all understand what we're to do," replied Glennie, "but I'll be hanged if I know why we're to do it."

"You'll know—perhaps sooner than you imagine."

Matt, stripped to his trousers, stepped to the landward side of the boat.

"Sharks always go in pairs, mate," cautioned Dick.

"If you see one take after me, Dick," returned Matt, "treat it the same as I did the one that took after you."

With hardly a splash Matt dropped into the water and swam toward the beach.
