The impetus given to the raft carried it on a little farther, but Will soon reached it, sprang, and almost fell over struggling Robert. No need to make him a prisoner; both hands and feet were bound fast by the long rope.

Will’s first act was to liberate poor Carlo, and take off his muzzle.

Bob groaned and shivered, but the noble dog stretched himself and frisked about the raft, scarcely noticing him.

“Carlo, Carlo, come, Carlo,” Stephen called joyously.

Carlo plunged into the river and swam towards his master, who, half beside himself with exultation, cried: “Steer for this port, Will; and bring the prisoner.”

“All right!” Will shouted back, and put the raft to the bank to take on Marmaduke and Jim, who soon came up.

The raft sank low under the weight of the four, but still it floated them; and Will and Marmaduke took up the oars and began to work their way slowly across the stream. Jim sat on the cage and pretended to steer; but his eyes roved from the prisoner to the boys on the opposite bank, and then, by way of the oarsmen, back to the prisoner.

The hearts of the six beat loud with triumph; but poor Bob’s heart sank, and beat very faint. “Oh,” he gasped piteously from among the serpent-like coils of the rope, “Oh, let me go! For mercy’s sake, let me go! Don’t take me over to Stephen and his dog; and I’ll promise never to meddle with you boys any more.”

Will looked pityingly at the abject creature, but answered with firmness: “No, Bob, I must take you to Stephen. You have played a mean trick on him, and he must settle with you. But,” whispering in his ear, “I guess you’ll survive.”
