Arthur stood at the window of his office and stared out toward the west. The sun was setting, but upon what a scene!

Where, from this same window Arthur had seen the sun setting behind the Jersey hills, all edged with the angular roofs of factories, with their chimneys emitting columns of smoke, he now saw the same sun sinking redly behind a ma.s.s of luxuriant foliage. And where he was accustomed to look upon the tops of high buildings--each ent.i.tled to the name of "skysc.r.a.per"--he now saw miles and miles of waving green branches.

The wide Hudson flowed on placidly, all unruffled by the arrival of this strange monument upon its sh.o.r.es--the same Hudson Arthur knew as a busy thoroughfare of puffing steamers and chugging launches.

Two or three small streams wandered unconcernedly across the land that Arthur had known as the most closely built-up territory on earth. And far, far below him--Arthur had to lean well out of his window to see it--stood a collection of tiny wigwams. Those small bark structures represented the original metropolis of New York.

His telephone rang. Van Deventer was on the wire. The exchange in the building was still working. Van Deventer wanted Arthur to come down to his private office. There were still a great many things to be settled--the arrangements for commandeering offices for sleeping quarters for the women, and numberless other details. The men who seemed to have best kept their heads were gathering there to settle upon a course of action.

Arthur glanced out of the window again before going to the elevator. He saw a curiously compact dark cloud moving swiftly across the sky to the west.

"Miss Woodward," he said sharply, "What is that?"

Estelle came to the window and looked.

"They are birds," she told him. "Birds flying in a group. I've often seen them in the country, though never as many as that."

"How do you catch birds?" Arthur asked her. "I know about shooting them, and so on, but we haven't guns enough to count. Could we catch them in traps, do you think?"

"I wouldn't be surprised," said Estelle thoughtfully. "But it would be hard to catch many."

"Come down-stairs," directed Arthur. "You know as much as any of the men here, and more than most, apparently. We're going to make you show us how to catch things."

Estelle smiled, a trifle wanly. Arthur led the way to the elevator. In the car he noticed that she looked distressed.

"What's the matter?" he asked. "You aren't really frightened, are you?"

"No," she answered shakily, "but--I'm rather upset about this thing. It's so--so terrible, somehow, to be back here, thousands of miles, or years, away from all one's friends and everybody."

"Please"--Arthur smiled encouragingly at her--"please count me your friend, won't you?"

She nodded, but blinked back some tears. Arthur would have tried to hearten her further, but the elevator stopped at their floor. They walked into the room where the meeting of cool heads was to take place.

No more than a dozen men were in there talking earnestly but dispiritedly. When Arthur and Estelle entered Van Deventer came over to greet them.

"We've got to do something," he said in a low voice. "A wave of homesickness has swept over the whole place. Look at those men. Every one is thinking about his family and contrasting his cozy fireside with all that wilderness outside."

"You don't seem to be worried," Arthur observed with a smile.

Van Deventer's eyes twinkled.

"I'm a bachelor," he said cheerfully, "and I live in a hotel. I've been longing for a chance to see some real excitement for thirty years. Business has kept me from it up to now, but I'm enjoying myself hugely."

Estelle looked at the group of dispirited men.

"We'll simply have to do something," she said with a shaky smile. "I feel just as they do. This morning I hated the thought of having to go back to my boarding-house to-night, but right now I feel as if the odor of cabbage in the hallway would seem like heaven."

Arthur led the way to the flat-topped desk in the middle of the room.

"Let's settle a few of the more important matters," he said in a businesslike tone. "None of us has any authority to act for the rest of the people in the tower, but so many of us are in a state of blue funk that those who are here must have charge for a while. Anybody any suggestions?"

"Housing," answered Van Deventer promptly. "I suggest that we draft a gang of men to haul all the upholstered settees and rugs that are to be found to one floor, for the women to sleep on."

"M--m. Yes. That's a good idea. Anybody a better plan?"

No one spoke. They all still looked much too homesick to take any great interest in anything, but they began to listen more or less half-heartedly.

"I've been thinking about coal," said Arthur. "There's undoubtedly a supply in the bas.e.m.e.nt, but I wonder if it wouldn't be well to cut the lights off most of the floors, only lighting up the ones we're using."

"That might be a good idea later," Estelle said quietly, "but light is cheering, somehow, and every one feels so blue that I wouldn't do it to-night. To-morrow they'll begin to get up their resolution again, and you can ask them to do things."

"If we're going to starve to death," one of the other men said gloomily, "we might as well have plenty of light to do it by."

"We aren't going to starve to death," retorted Arthur sharply. "Just before I came down I saw a great cloud of birds, greater than I had ever seen before. When we get at those birds--"

"When," echoed the gloomy one.

"They were pigeons," Estelle explained. "They shouldn't be hard to snare or trap."

"I usually have my dinner before now," the gloomy one protested, "and I'm told I won't get anything to-night."

The other men began to straighten their shoulders. The peevishness of one of their number seemed to bring out their latent courage.

"Well, we've got to stand it for the present," one of them said almost philosophically. "What I'm most anxious about is getting back. Have we any chance?"

Arthur nodded emphatically.

"I think so. I have a sort of idea as to the cause of our sinking into the Fourth Dimension, and when that is verified, a corrective can be looked for and applied."

"How long will that take?"

"Can't say," Arthur replied frankly. "I don't know what tools, what materials, or what workmen we have, and what's rather more to the point, I don't even know what work will have to be done. The pressing problem is food."

"Oh, bother the food," some one protested impatiently. "I don't care about myself. I can go hungry to-night. I want to get back to my family."

"That's all that really matters," a chorus of voices echoed.

"We'd better not bother about anything else unless we find we can't get back. Concentrate on getting back," one man stated more explicitly.

"Look here," said Arthur incisively. "You've a family, and so have a great many of the others in the tower, but your family and everybody else's family has got to wait. As an inside limit, we can hope to begin to work on the problem of getting back when we're sure there's nothing else going to happen. I tell you quite honestly that I think I know what is the direct cause of this catastrophe. And I'll tell you even more honestly that I think I'm the only man among us who can put this tower back where it started from. And I'll tell you most honestly of all that any attempt to meddle at this present time with the forces that let us down here will result in a catastrophe considerably greater than the one that happened to-day."

"Well, if you're sure--" some one began reluctantly.

"I am so sure that I'm going to keep to myself the knowledge of what will start those forces to work again," Arthur said quietly. "I don't want any impatient meddling. If we start them too soon G.o.d only knows what will happen."
