of which it is constructed, is vibrating. I mean no simple
vibration. Do not picture the physical swing of a pendulum. Rather,
the intricate total of all the movements of every tiny electron of
which your body is built. Remember, in the last analysis, your body is
merely movement--vibration--a vortex of Nothingness. You have, then, a
certain vibratory factor.

You take your place then upon the Time-scroll at a point where your
inherent vibratory factor is compatible with the scroll. You are in
tune; in tune as a radio receiver tunes in with etheric waves to make
them audible. Or, to keep the heat analogy, it is as though the
scroll, at the point where the temperature is 70 deg.F, will tolerate
nothing upon it save entities of that register.

And so, at that point on the scroll, the myriad things, in myriad
positions which make up the Cosmos, lie quiescent. But their existence is
only instantaneous. They have no duration. At once, they are blotted out
and re-exist. But now they have changed their vibratory combinations. They
exist a trifle differently--and the Time-scroll passes them along to the
new position. On a motion picture film you would call it the next frame,
or still picture. In radio you would say it has a trifle different tuning.
Thus we have a pseudo-movement--Events. And we say that Time--the
Time-scroll--keeps them separate. It is we who change--who seem to move,
shoved along so that always we are compatible with Time.

And thus is Time-traveling possible. With a realization of what I have
here summarized, Harl and the cripple Tugh made an exhaustive study of
the vibratory factors by which Matter is built up into form, and
seeming solidity. They found what might be termed the Basic Vibratory
Factor--the sum of all the myriad tiny movements. They found this
Basic Factor identical for all the material bodies when judged
simultaneously. But, every instant, the Factor was slightly changed.
This was the natural change, moving us a little upon the Time-scroll.

They delved deeper, until, with all the scientific knowledge of their
age, they were able with complicated electronic currents to alter the
Basic Vibratory Factors; to tune, let us say, a fragment or something
to a different etheric wave-length.

They did that with a small material particle--a cube of metal. It
became wholly incompatible with its _Present_ place on the
Time-scroll, and whisked away to anoth
