“That's so, dear,” she answered. “But where can you find the sort of telescope you need?”

“In Boston--in Cambridge, rather. The Harvard observatory has the biggest one within striking distance. What do you say to our making our trial trip in the boat, up the Sound and around Cape Cod, to Boston? We can spend a week there, then slant away for wherever we may decide to pass the winter. How does that suit you, Beta?”

She put away her work, and for a moment sat looking in at the flames that went leaping up the huge boulder chimney. The room glowed with warmth and light that drove away the cheerlessness of a foggy, late August drizzle.

“Do you really think we're wise to--to leave our home, with winter coming on?” she asked at length, pensively, the firelight casting its glow across her cheek and glinting in her eyes.

“Wise? Yes. We can't stay here, that's certain. And what is there to fear out in the world? With our firearms and our knowledge of fire itself, our science and our human intelligence, we're far more than a match for all enemies, whether of the beast-world or of that race of the Horde. I hate, in a way, to revisit the ruins of New York, for more ammunition and canned stuffs. The place is to o ghastly, too hideous, now, after the big fight.

“Boston will be a clean ground for us, with infinite resources. And as I said before, there's the Cambridge observatory. It's only two or three miles back in the forest, from the coast; maybe not more than half a mile from some part of the Charles River. We can sail up, camp on Soldiers' Field, and visit it easily. Why not?”

He sat down on the tiger-rug before the fire, near the girl. She drew his head down into her lap; then, when he was lying comfortably, began playing with his thick hair, as he loved so well to have her do.

“If you think it's all right, Allan,” said she, “we'll go. I want what you want.”

“That's my good girl!” exclaimed the engineer. “We'll be ready to start in a few days now. The boat's next thing to finished. What with the breadfruit, smoked steer and buffalo meat, hams and canned goods now on our shelves, we've certainly got enough supplies to stock her a two months' trip.

“Even with less, we'd be safe in starting. You see, the world's lain untouched by mankind for so many centuries that all the blighting effect of man's folly and greed and general piracy has vanished.
