The Runaway Skyscraper Part 2

III.

It was very still in the office. Except for the flickering outside everything seemed very much as usual. The electric light burned steadily, but Estelle was sobbing with fright and Arthur was trying vainly to console her.

"Have I gone crazy?" she demanded between her sobs.

"Not unless I've gone mad, too," said Arthur soothingly. The excitement had quite a soothing effect upon him. He had ceased to feel afraid, but was simply waiting to see what had happened. "We're way back before the founding of New York now, and still going strong."

"Are you sure that's what has happened?"

"If you'll look outside," he suggested, "you'll see the seasons following each other in reverse order. One moment the snow covers all the ground, then you catch a glimpse of autumn foliage, then summer follows, and next spring."

Estelle glanced out of the window and covered her eyes.

"Not a house," she said despairingly. "Not a building. Nothing, nothing, nothing!"

Arthur slipped, his arm about her and patted hers comfortingly.

"It's all right," he rea.s.sured her. "We'll bring up presently, and there we'll be. There's nothing to be afraid of."

She rested her head on his shoulder and sobbed hopelessly for a little while longer, but presently quieted. Then, suddenly, realizing that Arthur's arm was about her and that she was crying on his shoulder, she sprang away, blushing crimson.

Arthur walked to the window.

"Look there!" he exclaimed, but it was too late. "I'll swear to it I saw the Half Moon, Hudson's ship," he declared excitedly.

"We're way back now, and don't seem to be slacking up, either."

Estelle came to the window by his side. The rapidly changing scene before her made her gasp. It was no longer possible to distinguish night from day.

A wavering streak, moving first to the right and then to the left, showed where the sun flashed across the sky.

"What makes the sun wabble so?" she asked.

"Moving north and south of the equator," Arthur explained casually. "When it's farthest south--to the left--there's always snow on the ground. When it's farthest right it's summer. See how green it is?"

A few moments' observation corroborated his statement.

"I'd say," Arthur remarked reflectively, "that it takes about fifteen seconds for the sun to make the round trip from farthest north to farthest south." He felt his pulse. "Do you know the normal rate of the heart-beat? We can judge time that way. A clock will go all to pieces, of course."

"Why did your watch explode--and the clock?"

"Running forward in time unwinds a clock, doesn't it?" asked Arthur. "It follows, of course, that when you move it backward in time it winds up. When you move it too far back, you wind it so tightly that the spring just breaks to pieces."

He paused a moment, his fingers on his pulse.

"Yes, it takes about fifteen seconds for all the four seasons to pa.s.s. That means we're going backward in time about four years a minute. If we go on at this rate another hour we'll be back in the time of the Northmen, and will be able to tell if they did discover America, after all."

"Funny we don't hear any noises," Estelle observed. She had caught some of Arthur's calmness.

"It pa.s.ses so quickly that though our ears hear it, we don't separate the sounds. If you'll notice, you do hear a sort of humming.

It's very high-pitched, though."

Estelle listened, but could hear nothing.

"No matter," said Arthur. "It's probably a little higher than your ears will catch. Lots of people can't hear a bat squeak."

"I never could," said Estelle. "Out in the country, where I come from, other people could hear them, but I couldn't."

They stood a while in silence, watching.

"When are we going to stop?" asked Estelle uneasily. "It seems as if we're going to keep on indefinitely."

"I guess we'll stop all right," Arthur rea.s.sured her. "It's obvious that whatever it was, only affected our own building, or we'd see some other one with us. It looks like a fault or a flaw in the rock the building rests on. And that can only give so far."

Estelle was silent for a moment.

"Oh, I can't be sane!" she burst out semihysterically. "This can't be happening!"

"You aren't crazy," said Arthur sharply. "You're sane as I am. Just something queer is happening. Buck up. Say your multiplication tables. Say anything you know. Say something sensible and you'll know you're all right. But don't get frightened now. There'll be plenty to get frightened about later."

The grimness in his tone alarmed Estelle.

"What are you afraid of?" she asked quickly.

"Time enough to worry when it happens," Arthur retorted briefly.

"You--you aren't afraid we'll go back before the beginning of the world, are you?" asked Estelle in sudden access of fright.

Arthur shook his head.

"Tell me," said Estelle more quietly, getting a grip on herself. "I won't mind. But please tell me."

Arthur glanced at her. Her face was pale, but there was more resolution in it than he had expected to find.

"I'll tell you, then," he said reluctantly. "We're going back a little faster than we were, and the flaw seems to be a deeper one than I thought. At the roughest kind of an estimate, we're all of a thousand years before the discovery of America now, and I think nearer three or four. And we're gaining speed all the time. So, though I am as sure as I can be sure of anything that we'll stop this cave-in eventually, I don't know where. It's like a creva.s.se in the earth opened by an earthquake which may be only a few feet deep, or it may be hundreds of yards, or even a mile or two. We started off smoothly. We're going at a terrific rate. _What will happen when we stop?_"

Estelle caught her breath.

"What?" she asked quietly.

"I don't know," said Arthur in an irritated tone, to cover his apprehension. "How could I know?"

Estelle turned from him to the window again.

"Look!" she said, pointing.

The flickering had begun again. While they stared, hope springing up once more in their hearts, it became more p.r.o.nounced. Soon they could distinctly see the difference between day and night.

They were slowing up! The white snow on the ground remained there for an appreciable time, autumn lasted quite a while. They could catch the flashes of the sun as it made its revolutions now, instead of its seeming like a ribbon of fire. At last day lasted all of fifteen or twenty minutes.
