far he was about to fall asleep, when a single red flash lighted up the peak of the canvas pile, then faded. He thought of the red ball of fire he had taken for a cat’s eye. He remembered the yellow glow he had seen when with Pant on other occasions. His mind attacked the problem weakly. He was half asleep. In another second the click-click of the car wheels was heard only in his dreams. CHAPTER II BOXING THE BUNCO-STEERER From time to time during the night, Johnny awoke to listen for a moment to the click-click of the wheels. Once he thought he caught again the play of that crimson flash upon the canvas. Once he remained awake long enough to do a little wondering and planning. How had Pant, his friend of other days, come aboard this circus train? What was he seeking? True, Johnny had received a letter from this strange fellow some time before, in which he spoke in mysterious terms of a three-ring circus and the Secret Service, but Johnny had taken this very much as a joke.

It had been the utmost folly for Marjory to wear her mother’s engagement ring, set with an immense solitaire, dangling on a chain, when they attended the circus, yet she had done it, and Johnny had promised to watch it. He had kept a sharp lookout, but had been caught unawares when the thief had proved to be an elephant, who doubtless had taken it for something to eat, and, having scratched his trunk upon it, had tossed it to his lady friends of the human species, to see what they thought of it. “Rotten luck!” Johnny grumbled, as he turned over once more to fall asleep. By a succession of sudden stops and starts, by the bumping of cars, and the grinding of brakes, Johnny realized that at last they had come to a stopping place. When the starting and stopping had continued for some time, he knew the city they were entering was a large
