weight of the tower.

Arthur knew, however, that long concrete piles reached far down to
bedrock. It was these piles that had sunk into the Fourth Dimension,
carrying the building with them.

Arthur had followed the plans with great interest when the
Metropolitan was constructed. It was an engineering feat, and in
the engineering periodicals, whose study was a part of Arthur's
business, great space had been given to the building and the methods
of its construction.

While examining the earth carefully he went over his theory of the
cause for the catastrophe. The whole structure must have sunk at
the same time, or it, too, would have disintegrated, as the other
buildings had appeared to disintegrate. Mentally, Arthur likened
the submergence of the tower in the oceans of time to an elevator
sinking past the different floors of an office building. All about
the building the other sky-scrapers of New York had seemed to
vanish. In an elevator, the floors one passes seem to rise upward.

Carrying out the analogy to its logical end, Arthur reasoned that the
building itself had no more cause to disintegrate, as the buildings
it passed seemed to disintegrate, than the elevator in the office
building would have cause to rise because its surroundings seemed
to rise.

Within the building, he knew, there were strange stirrings of
emotions. Queer currents of panic were running about, throwing
the people to and fro as leaves are thrown about by a current of
wind. Yet, underneath all those undercurrents of fear, was a rapidly
growing resolution, strengthened by an increasing knowledge of the
need to work.

Men were busy even then shifting all possible comfortable furniture
to a single story for the women in the building to occupy. The
men would sleep on the floor for the present. Beds of boughs could
be improvised on the morrow. At sunrise on the following morning
many men would go to the streams to fish, guarded by other men. All
would be frightened, no doubt, but there would be a grim resolution
underneath the fear. Other men would wander about to hunt.

There was little likelihood of Indians approaching for some days, at
least, but when they did come Arthur meant to avoid hostilities by
all possible means. The Indians would be fearful of their strange
visitors, and it should not be difficult to convince them that
friendliness was safest, even if they displayed unfriendly desires.

The pressing problem was food. There were
