"Shall I drop the fellow?" quivered Ted.

"No," came Halstead's quick answer. Then, as Frank Rollings summoned the strength to wheel about as if to bolt, Halstead shouted, warningly:

"Rollings, if you try to move, you won't get three steps away!"

At this instant one of the United States deputy marshals came up over the rail.

"Officer," called Tom, "there's the man you've cruised so far to arrest."

Though he had a rifle strapped over his back, the marshal drew his revolver as he ran forward.

"Frank Rollings, you're a United States prisoner. Put up your hands!"

With a moan that was half a scream, Rollings, instead, sank to the deck in a huddled heap.
