"That means the end of the word," the boy thought, "and the word is 'COME.' Now, I wonder if he will?"

Frank kept up his odd motions, at which the Filipino seemed greatly amused, and French turned away to the alcohol stove to prepare a cup of hot cocoa. But the motions were only for effect now, and meant nothing. There was a light movement in the thicket, and three figures, crawling low, entered the canoe which the guard had left the Manhattan in and moved noiselessly toward the boat.

The Filipino's back was turned to the beach, for he was watching Frank. French was busy with his cocoa, condensed cream, and sugar, and so the advancing canoe was not observed until it was within a few feet of the boat. Then the guard uttered a cry of warning and raised his gun.

Frank was ready for this and the distance between himself and the guard was well calculated. He launched himself like a catapult-dart against the slim figure, and was fortunate enough to seize the gun. Frank was an adept at the Japanese ju-jitsu game, and, much to the astonishment of the Filipino, he soon found himself, minus his gun, dropping to the bottom of the bay.

French, of course, started out of the cabin, revolver in hand, but when he stooped his tall figure in the low doorway he did not straighten it again as readily as he had expected to. Jack was on the back of his neck and shoulders, pressing him down to the bridge deck. But French was a strong man and Jack would have soon been thrown aside had Frank not engaged him.

When Ned, Pat and Jimmie sprang out of the canoe and gained the cockpit, the three were in a tangle, with Frank sitting on the hand which held the weapon. French surrendered the revolver and sat up with a sickly grin on his face when he saw the three bending over him, ready to take a hand in the proceedings.

"You win!" he said. "I know when I hold the low hand!"

"Didn't I tell you," Frank said, as soon as he could catch his breath, "that the motions you saw were calculated to bring the muscles of the body into action? Well, they did, didn't they?"

"Rather!" French replied. "Now, if you'll pull this ambitious young man off my back, I'll get into an easier position."

"You're a good fellow," Jack said, "and I'll do as you say, only you've got to behave yourself, you know."
