After a while, both calmer grown, they looked again from the high window.
"See!" exclaimed the engineer, and pointed.
There, far away to westward, a few straggling lights--only a very few--slowly and uncertainly were making their way across the broad black breast of the river.
Even as the man and woman watched, one vanished. Then another winked out, and did not reappear. No more than fifteen seemed to reach the Jersey shore, there to creep vaguely, slowly away and vanish in the dense primeval woods.
"Come," said Stern at last. "We must be going, too. The night's half spent. By morning we must be very far away."
"What? We've got to leave the city?"
"Yes. There's no such thing as staying here now. The tower's quite untenable. Racked and shaken as it is, it's liable to fall at any time. But, even if it should stand, we can't live here any more."
"But--where now?"
"I don't just know. Somewhere else, that's certain. Everything in this whole vicinity is ruined. The spring's gone. Nothing remains of the forest, nothing but horror and death. Pestilence is bound to sweep this place in the wake of such a--such an affair.
"The sights all about here aren't such as you should see. Neither should I. We mustn't even think of them. Some way or other we can find a path down out of here, away--away--"
"But," she cried anxiously, "but all our treasures? All the tools and dishes, all the food and clothing, and everything? All our precious, hard-won things?"
"Nothing left of them now. Down on the fifth floor, at that end of the building, I'm positive there's nothing but a vast hole blown out of the side of the tower. So there's nothing left to salvage. Nothing at all."
"Can you replace the things?"
"Why not? Wherever we settle down we can get along for a few days on what game I can snare or shoot with the few remaining cartridges. And after that--"
"Yes?"
"After that, once we get established a little, I can come into the city and go to raiding again. What we've lost is a mere trifle compared to what's left in New York. Why, the latent resources of this vast ruin haven't been even touched yet! We've got our lives. That's the only vital factor. With those everything else is possible. It all looks dark and hard to you now, Beatrice. But in a few days--wait and see!"
"Allan!"
"What, Beatrice?"
"I trust you in everything. I'm in your hands. Lead me."
"Come, then, for the way is long before us. Come!"
Two hours later, undaunted by the far howling of a wolfpack, as the wan crescent of the moon came up the untroubled sky, they reached the brink of the river, almost due west of where the southern end of Central Park hall been.
