Arthur continued to stare about.
"No danger," he said weakly. "Just the floor of the one room gave way. The aftermath of the rock-flaw."
He made his way across the splintered flooring and piled-up chairs.
"We're on top of the safe-deposit vault," he said. "That's why we didn't fall all the way to the floor below. I wonder how we're going to get down?"
Estelle followed him, still frightened for fear of the building falling upon them. Some of the long floor-boards stretched over the edge of the vault and rested on a tall, bronze grating that protected the approach to the massive strong-box. Arthur tested them with his foot.
"They seem to be pretty solid," he said tentatively.
His strength was coming back to him every moment. He had been no more than stunned. He walked out on the planking to the bronze grating and turned.
"If you don't get dizzy, you might come on," he said. "We can swing down the grille here to the floor."
Estelle followed gingerly and in a moment they were safely below. The corridor was quite empty.
"When the crash came," Estelle explained, her voice shaking with the reaction from her fear of a moment ago, "every one thought the building was coming to pieces, and ran out. I'm afraid they've all run away."
