Chapter 12

It was two weeks later. Estelle looked out over the now familiar wild landscape. It was much the same when she looked far away, but near by there were great changes.

A cleared trail led through the woods to the waterfront, and a raft of logs extended out into the river for hundreds of feet. Both sides of the raft were lined with busy fishermen--men and women, too. A little to the north of the base of the building a huge mound of earth smoked sullenly. The coal in the cellar had given out and charcoal had been found to be the best substitute they could improvise. The mound was where the charcoal was made.

It was heart-breaking work to keep the fires going with charcoal, because it burned so rapidly in the powerful draft of the furnaces, but the original fire-room gang had been recruited to several times its original number from among the towerites, and the work was divided until it did not seem hard.

As Estelle looked down two tiny figures sauntered across the clearing from the woods with a heavy animal slung between them. One of them was using a gun as a walking-stick. Estelle saw the flash of the sun on its polished metal barrel.

There were a number of Indians in the clearing, watching with wide-open eyes the activities of the whites. Dozens of birch-bark canoes dotted the Hudson, each with its load of fishermen, industriously working for the white people. It had been hard to overcome the fear in the Indians, and they still paid superstitious reverence to the whites, but fair dealings, coupled with a constant readiness to defend themselves, had enabled Arthur to institute a system of trading for food that had so far proved satisfactory.

The whites had found spare electric-light bulbs valuable currency in dealing with the redmen. Picture-wire, too, was highly prized. There was not a picture left hanging in any of the offices. Metal paper-knives bought huge quantities of provisions from the eager Indian traders, and the story was current in the tower that Arthur had received eight canoe-loads of corn and vegetables in exchange for a broken-down typewriter. No one could guess what the savages wanted with the typewriter, but they had carted it away triumphantly.

Estelle smiled tenderly to herself as she remembered how Arthur had been the leading spirit in all the numberless enterprises in which the castaways had been forced to engage. He would come to her in a spare ten minutes, and tell her how everything was going. He seemed curiously boylike in those moments.

Sometimes he would come straight from the fire-room--he insisted on taking part in all the more arduous duties--having hastily cleaned himself for her inspection, snatch a hurried kiss, and then go off, laughing, to help chop down trees for the long fishing-raft. He had told them how to make charcoal, had taken a leading part in establishing and maintaining friendly relations with the Indians, and was now down in the deepest sub-basement, working with a gang of volunteers to try to put the building back where it belonged.

Estelle had said, after the collapse of the flooring in the board-room, that she heard a sound like the rushing of waters. Arthur, on examining the floor where the safe-deposit vault stood, found it had risen an inch. On these facts he had built up his theory. The building, like all modern sky-scrapers, rested on concrete piles extending down to bedrock. In the center of one of those piles there was a hollow tube originally intended to serve as an artesian well. The flow had been insufficient and the well had been stopped up.

Arthur, of course, as an engineer, had studied the construction of the building with great care, and happened to remember that this partly hollow pile was the one nearest the safe-deposit vault. The collapse of the board-room floor had suggested that some change had happened in the building itself, and that was found when he saw that the deposit-vault had actually risen an inch.

He at once connected the rise in the flooring above the hollow pile with the pipe in the pile. Estelle had heard liquid sounds. Evidently water had been forced into the hollow artesian pipe under an unthinkable pressure when the catastrophe occurred.

From the rumbling and the suddenness of the whole catastrophe a volcanic or seismic disturbance was evident. The connection of volcanic or seismic action with a flow of water suggested a geyser or a hot spring of some sort, probably a spring which had broken through its normal confines some time before, but whose pressure had been sufficient to prevent the accident until the failure of its flow.

When the flow ceased the building sank rapidly. For the fact that this “sinking” was in the fourth direction--the Fourth Dimension--Arthur had no explanation. He simply knew that in some mysterious way an outlet for the pressure had developed in that fashion, and that the tower had followed the spring in its fall through time.

The sole apparent change in the building had occurred above the one hollow concrete pile, which seemed to indicate that if access were to be had to the mysterious, and so far only assumed spring, it must be through that pile. While the vault retained its abnormal elevation, Arthur believed that there was still water at an immense and incalculable pressure in the pipe. He dared not attempt to tap the pipe until the pressure had abated.

At the end of a week he found the vault slowly settling back into place. When its return to the normal was complete he dared begin boring a hole to reach the hollow tube in the concrete pile.

As he suspected, he found water in the pile--water whose sulfurous and mineral nature confirmed his belief that a geyser reaching deep into the bosom of the earth, as well as far back in the realms of time, was at the bottom of the extraordinary jaunt of the tower.

Geysers were still far from satisfactory things to explain. There are many of their vagaries which we cannot understand at all. We do know a few things which affect them, and one thing is that “soaping” them will stimulate their flow in an extraordinary manner.

Arthur proposed to “soap” this mysterious geyser when the renewal of its flow should lift the runaway sky-scraper back to the epoch from which the failure of the flow had caused it to fall.

He made his preparations with great care. He confidently expected his plan to work, and to see the sky-scraper once more towering over mid-town New York as was its wont, but he did not allow the fishermen and hunters to relax their efforts on that account. They labored as before, while deep down in the sub-basement of the colossal building Arthur and his volunteers toiled mightily.

They had to bore through the concrete pile until they reached the hollow within it. Then, when the evidence gained from the water in the pipe had confirmed his surmises, they had to prepare their “charge” of soapy liquids by which the geyser was to be stirred to renewed activity.
