"Ah!" Adolf smiled satirically. "That cost a heap!" he said. "Well?"

"I ask to be taken aboard for this world trip. Can they refuse me?"

It was his companion's turn to show some irritation. If Carl Reitberg had the intention of accompanying the great airship on her voyage, then it could be with one object, for there were no secrets between these two rascals. He desired to gain access to the ship with the sole idea of wrecking or damaging it. Very good, that! Crafty! Quite commendable.

"But there's myself to be considered. If he succeeds, what do I get? Where is the reward promised?"

The ruffian eyed Carl with undisguised contempt, and yet half fearfully.

"Clever idea, very," he said aloud. "You go aboard for the trip. There is, perhaps, an accident. Unfortunate, of course, but—er—necessary. You are as sorry as the others. You express a thousand regrets—but all the while you are laughing in your sleeve. You are really thinking of something far harder to give than regrets; you are thinking of your one hundred thousand pounds, eh, my friend? That is, I think, the beginning and end of the inspiration."

It was so obvious that Adolf admired the craftiness of the scheme that Carl almost forgave him. But the next few seconds undeceived him, and reminded the magnate of the fact that he had others to consider.

"Of course," said Adolf slowly, "our bargain holds good. If—if there is an unfortunate accident, and the voyage of the airship is arrested, you return and pay me the sum promised."
