FATHER AND SON--CONCLUSION, 252 YOUNG CAPTAIN JACK. CHAPTER I. THE ENCOUNTER ON THE BRIDGE. "Get out of the way, boy, or I'll ride over you!" "Wait a second, please, until I haul in this fish. He's such a beauty I don't wish to lose him." "Do you suppose I'm going to bother with your fish? Get out of the way, I say!" And the man, who sat astride of a coal-black horse, shook his hand threateningly. He was dressed in the uniform of a surgeon in the Confederate Army, and his face was dark and crafty. The boy, who was but fourteen and rather slenderly built, looked up in surprise. He was seated on the side of a narrow bridge spanning a mountain stream flowing into the ocean, and near him rested a basket half-filled with fish. He had been on the point of hauling in another fish--of extra size--but now his prize gave a sudden flip and disappeared from view. "Gone! and you made me miss him!" he cried, much vexed.
