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. It grew longer and longer. Then half an hour, then an hour. The sun wavered in midheaven and was still. Far below them, the watchers in the tower of the skyscraper saw trees swaying and bending in the wind. Though there was not a house or a habitation to be seen and a dense forest covered all of Manhattan Island, such of the world as they could see looked normal. Wherever or rather in whatever epoch of time they were, they had arrived. IV. Arthur caught at Estelle's arm and the two made a dash for the elevators. Fortunately one was standing still, the door open, on their floor. The elevator-boy had deserted his post and was looking with all the rest of the occupants of the building at the strange landscape that surrounded them. No sooner had the pair reached the car, however, than the boy came hurrying along the corridor, three or four other people following him also at a run. Without a word the boy rushed inside, the others crowded after him, and the car shot downward, all of the newcomers panting from their sprint. Theirs was the first car to reach the bottom. They rushed out and to the western door. Here, where they had been accustomed to see Madison Square spread out before them, a clearing of perhaps half an acre in extent showed itself. Where their eyes instinctively looked for the dark bronze fountain, near which soap-box orators aforetime held sway, they saw a tent, a wigwam of hides and bark gaily painted. And before the wigwam were two or three brown-skinned Indians, utterly petrified with astonishment. Behind the first wigwam were others, painted like the first with daubs of brightly colored clay. From them, too, Indians issued, and stared in incredulous amazement, their eyes growing wider and wider. When the group of white people confronted the Indians there was a moment's deathlike silence. Then, with a wild yell, the redskins broke and ran, not stopping to gather together their belongings, nor pausing for even a second glance at the weird strangers who invaded their domain. Arthur took two or three deep breaths of the fresh air and found himself even then comparing its quality with that of the city. Estelle stared about her with unbelieving eyes. She turned and saw the great bulk of the office building behind her, then faced this small clearing with a virgin forest on its farther side. She found herself trembling from some undefined cause. Arthur glanced at her. He saw the trembling and knew she would have a fit of nerves in a moment if something did not come up demanding instant attention.
