Jack about this time evidently began to scent something with regard to Tom's intuitions; at least his word implied a growing skepticism concerning their ability to find room for two passengers aboard a plane intended only for a pilot and an observer, or a gunner.

"It certainly would, Jack; and that's why I'm forced to call on you to make a sacrifice."

"Go on and say what's on your mind, then," demanded Jack. "No matter what it's going to be, you'll find me ready and willing for anything."

"If it's possible to get back, yes," said the other.

"But if you can't make it, then to-morrow night, Tom?"
