“You don't want to go and leave me, Allan?”

“God forbid! Shall I abandon the whole attempt and settle down with you here, all alone, and--”

“No, no, no! Not that, Allan!”

“I knew you'd say so. After all, the future of the race means more than our own welfare or comfort or anything. Even our safety has got to be risked for it. So you see--”

She thought a moment, clinging to him, somewhat pale and shaken, but with an indefinable courage in her eyes. Then asked she:

“Wouldn't it be possible in some way--for you can do anything, Allan--wouldn't it be possible for you to build another machine? Surely in the ruins of some city not too far away, in Nashville, Cincinnati, or Detroit, you could find materials! Couldn't you make another aeroplane and teach me how to fly, so I could help you? I'd learn, Allan! I'd dare, and be brave--awfully brave, for your sake, and theirs, and--”

He gravely shook his head in negation.

“I know you would, dearest, but you mustn't. Half my real reason for not wanting you to go with me is just this danger of flying. You'll be safer here. With plenty of supplies and your pistol you'll be all right. I know it seems heartless to talk of leaving you, even for three days, but, after all, it's far the wisest way. We'll build a barricade and make a regular fort for you and stock it with supplies. Then you can wait for me and the first two settlers. And after that you'll have company. Why, you'll have subjects--for, until they're educated, we've simply got to rule these people. It'll be only the first trip that will make you lonely, and it won't be long.”

“I know; but suppose anything should happen to you!”

He laughed confidently.
