Came now the evening, as they sat and talked together, talked long and earnestly, there within that ruined place. Too eager for some knowledge of the truth, they, to feel hunger or to think of their lack of clothing.
Chairs they had none, nor even so much as a broom to clean the floor with. But Stern, first-off, had wrenched a marble slab from the stairway.
And with this plank of stone still strong enough to serve, he had scraped all one corner of the office floor free of rubbish. This gave them a preliminary camping-place wherein to take their bearings and discuss what must be done.
"So then," the engineer was saying as the dusk grew deeper, "so then, we'll apparently have to make this building our headquarters for a while.
"As nearly as I can figure, this is about what must have happened. Some sudden, deadly, numbing plague or cataclysm must have struck the earth, long, long ago.
"It may have been an almost instantaneous onset of some new and highly fatal micro-organism, propagating with such marvelous rapidity that it swept the world clean in a day--doing its work before any resistance could be organized or thought of.
"Again, some poisonous gas may have developed, either from a fissure in the earth's crust, or otherwise. Other hypotheses are possible, but of what practical value are they now?
"We only know that here, in this uppermost office of the Tower, you and I have somehow escaped with only a long period of completely suspended animation. How long? God alone knows! That's a query I can't even guess the answer to as yet."
"Well, to judge by all the changes," Beatrice suggested thoughtfully, "it can't have been less than a hundred years. Great Heavens!" and she burst into a little satiric laugh. "Am I a hundred and twenty-four years old? Think of that!"
"You underestimate," Stern answered. "But no matter about the time question for the present; we can't solve it now.
"Neither can we solve the other problem about Europe and Asia and all the rest of the world. Whether London, Paris, Berlin, Rome, and every other city, every other land, all have shared this fate, we simply don't know.
"All we can have is a feeling of strong probability that life, human life I mean, is everywhere extinct--save right here in this room!
"Otherwise, don't you see, men would have made their way back here again, back to New York, where all these incalculable treasures seem to have perished, and--"
He broke short off. Again, far off, they heard a faint re-echoing roar. For a moment they both sat speechless. What could it be? Some distant wall toppling down? A hungry beast scenting its prey? They could not tell. But Stern smiled.
