everybody here will be better for hearing it. Anyway, everybody will have to know it before night. I took over the restaurant as you suggested, and posted some of the men from the bank that I knew I could trust about the doors. But there was hardly any use in doing it.
"The restaurant stocks up in the afternoon, as most of its business is in the morning and at noon. It only carries a day's stock of foodstuffs, and the—the cataclysm, or whatever it was, came at three o'clock. There is practically nothing in the place. We couldn't make sandwiches for half the women that are caught with us, let alone the men. Everybody will go hungry to-night. There will be no breakfast to-morrow, nor anything to eat until we either make arrangements with the Indians for some supplies or else get food for ourselves."
Arthur leaned his jaw on his hand and considered. A slow flush crept over his cheek. He was getting his fighting blood up.
At school, when he began to flush slowly his schoolmates had known the symptom and avoided his wrath. Now he was growing angry with mere circumstances, but it would be none the less unfortunate for those circumstances.
"Well," he said at last deliberately, "we've got to— What's that?"
There was a great creaking and groaning. Suddenly a sort of vibration was felt under foot. The floor began to take on a slight slant.
"Great Heaven!" some one cried. "The building's turning over and we'll be buried in the ruins!"
The tilt of the floor became more pronounced. An empty chair slid to one end of the room. There was a crash.
Arthur and Estelle in Conference
ARTHUR woke to find some one tugging at his shoulders, trying to drag him from beneath the heavy table, which had wedged itself across his feet and pinned him fast, while a flying chair had struck him on the head.
"Oh, come and help," Estelle's voice was calling deliberately. "Somebody come and help! He's caught in here!"
She was sobbing in a combination of panic and some unknown emotion.
"Help me, please!" she gasped, then her voice broke despondently, but she never ceased to tug ineffectually at Chamberlain, trying to drag him out of the mass of wreckage.
Arthur moved a little, dazedly.
"Are you alive?" she called anxiously. "Are you alive? Hurry, oh, hurry and wriggle out. The building's falling to pieces."
"I'm all right," Arthur said weakly. "You get out before it all comes down."
"I won't leave you," she declared. "Where are you caught? Are you badly hurt? Hurry, please hurry!"
Arthur stirred, but could not loosen his feet. He half-rolled over, and the table moved as if it had been precariously balanced, and slid heavily to one side. With Estelle still tugging at him, he managed to get to his feet on the slanting floor and started about him.
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."
"They'll be back in a little while," Arthur said, quietly.
They went along the big marble corridor to the same western door, out of which they had first gone to see the Indian village. As they emerged into the sunlight they met a few of the people who had already recovered from their panic and were returning.
A crowd of respectable size gathered in a few moments, all still pale and shaken, but coming back to the building which was their refuge. Arthur leaned wearily against the cold stone. It seemed to vibrate under his touch. He turned quickly to Estelle.
"Feel this !" he exclaimed.
She did so.
"I've been wondering what that rumble was," she said. "I've been hearing it ever since we landed here, but didn't understand where it came from."
"You hear a rumble?" Arthur asked, puzzled. "I can't hear anything."
"It isn't as loud as it was, but I hear it," Estella insisted. "It's very deep, like the lowest possible bass note of an organ."
"You couldn't hear the shrill whistle when we were coming here," Arthur exclaimed suddenly, "and you can't hear the squeak of a bat. Of course your ears are pitched lower than usual, and you can hear sounds that are lower than I can hear. Listen carefully. Does it sound in the least like a liquid rushing through somewhere?"
"Y-yes," said Estelle hesitatingly. "Somehow, I don't quite understand how, it gives me the impression of a tidal flow or something of that sort."
Arthur rushed indoors. When Estelle followed him she found him excitedly examining the marble floor about the base of the vault.
"It's cracked," he said excitedly. "It's cracked! The vault rose all of an inch!"
Estelle looked and saw the cracks.
