There was the ring. Gwen had it that morning; Millie had it two days before; perhaps Mitzi had it at this very moment. He was still surprised at himself because of his action of that morning. Well, he must have that ring. This, if for no other reason, must hold him to his surprising circus career. He wondered if Gwen were serious about the clown stunt and, if so, whether she would soon have it arranged. He thought again of Pant’s problem, and wondered for the hundredth time if he should have any part in its solving.

But the greatest mystery of all was the crimson flash. He had seen it leap down from the air and turn the tiger, loose in the big tent, blood red. He had seen it do the same thing in the animal tent. In his suggestion regarding the direction of the sun’s rays in the Arctic, Pant had intimated that rays of light could be made to follow crooked paths. If this could be done, if Pant held within his fertile brain the secret of this terrible power, what a wonderful fellow he was! How it would transform modern life, modern warfare! Trenches would be utterly useless once a light might be thrown upon them from any angle. Many things that were dark, secret and hidden in every day life would be clear as the light of day. What dark corner, what secret rendezvous, would be safe from the glare of those crooked rays of gleaming light?

Johnny pondered until his head whirled, then, rising and shaking himself, he made his way to the sleeping car in which he now bunked. The circus would soon be on its way to the next small city.

That next small city, if Johnny had but known it, was only ten miles from the home of the grandparents of the millionaire twins. They had ridden cross country for a visit to their grandparents. Along the roads they had seen glaring posters announcing the coming of the circus. They had decided at once that now was the time to join that circus. Their circus riding clothes were in the trunk, which had been sent on by express. Even as Johnny rose from beside the fire, the twins, in their beds at their grandfather’s rambling, old house, were planning how, on the morrow, they would slip on their circus garb underneath their dresses, and ride away to discover their old friend, Johnny, and join the parade.

Morning broke bright and clear on the old fair grounds of Rokford, which was the place of the great circus’ next one day stand. When Johnny had eaten breakfast, he strolled past the cooking tent and, having paused to admire the row of shining copper steam kettles, he thought of his promise to get in touch with the manager of these kettles. The cook was not in sight at that moment, so Johnny paused to study these great vats, which resembled nothing so much as giant kettle drums.

“Just a twist of the valve and the steam does the rest,” he murmured to himself.

“Great, ain’t they?” a voice said at his elbow.

“Sure are.” Johnny turned about. It was the cook. A tall, slender man, well past middle age, with a drooping mustache, and a wrinkled smile, he studied Johnny from head to toe.

“You’re a boxer,” he said, getting his smile into operation. “Saw you box a conman once. Been wonderin’ ever since how such a small fellow could pack such a wallop.”

“I don’t mind tellin’ you,” said Johnny. “It’s absurdly simple. Instead of just getting the force of your arm muscles into the blow, or the push of your shoulder, you leap as you strike, and that puts the whole of your body back of your mitt. That’s easy, isn’t it?”
