this unearthly visitor to their hunting grounds.

A tiny figure, dwarfed by the building whose base he skirted,
Arthur moved slowly about the vast pile. The earth seemed not to
have been affected by the vast 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.
