"I don't know how long," came back Darrow's voice calmly. "Next we will get out of the building. I want to make some observations. Get hold of my hand; we'll have to grope our way out."

"If we could only get a light," muttered Hallowell.

"You can't," stated Darrow.

They felt their way down the ten flights of stairs like blind men. A few inmates of the building they jostled, or passed, or picked up on the way.

"This settles it," one remarked profanely. "My lease quits. They can sue and be damned. I decline to have anything more to do with any freak-lined skyscraper of this description."

In the lower corridors Darrow halted them.

"Here's another thing," said he: "if I'm right, we should run out of this just eleven feet beyond the last elevator cage."

He felt his way along the grill, made four paces forward, and uttered a little cry of satisfaction. The two men followed him blindly. As though stepping from one room to another they emerged into glaring daylight!

Both involuntarily looked back. The darkness hung there like a curtain, just inside the outer walls of the building. Already a crowd had gathered to observe this new and strange phenomenon of the now celebrated Atlas Building. It was a curious and a facetious crowd, but not awestricken, as it had been at the first manifestations of this freakish upset of natural forces.

A man observing the flight of an aeroplane for the first time loses his sense of strangeness inside of a few minutes; and yet flying has been since the days of Icarus considered one of the impossible achievements. So the general public of Manhattan were becoming accustomed to reversals of form in the affairs of the physical world. The frivolous majority, having discovered nothing to be apprehended from the phenomena save a few hours' helplessness of a sort, and much to be gained through the savor of novelty, were inclined to an amused or irritated attitude, depending on the extent to which its occupations were interfered with. The minority took to religious meetings and interpretations.
