Which Shall Win?

Johnny was a little boy, but he had a wish When he went a-fishing, to haul in the biggest fish; Hook and line so strong as his, surely could not fail, Johnny thought, to catch a shark, or perchance, a whale. Early on a rainy day, Johnny on the shore Felt a tugging at his line, never felt before; Then he straightened up, and said, opening wide his eyes, “Cracky! now I guess I’ve got something like a prize!” Johnny pulled and tugged away; then he gave a look; Saw a monstrous turtle fastened firmly to his hook; Took a firmer hold and said, “Which of us shall win? I must either pull you out, or you’ll pull me in!”
