mers, coils and tubes, and reformed and reconnected them, under
Seaton's bulging eyes, into an entirely different mechanism.

"Oh, I see!" he gasped. "Say, what are you anyway?"

"Pardon me; in my eagerness I became forgetful. I am Orlon, the First of
Astronomy of Norlamin, in my observatory upon the surface of the planet.
This that you see is simply my projection, composed of forces for which
you have no name in your language. You can cut it off, if you wish, with
your ray-screens, which even I can see are of a surprisingly high order
of efficiency. There, this educator will now work very well. Please put
on the remodeled headsets, all four of you."

They did so, and the rays of force moved levers, switches, and dials as
positively as human hands could have moved them, and with infinitely
greater speed and precision. As the dials moved, each brain received
clearly and plainly a knowledge of the customs, language, and manners of
the inhabitants of Norlamin. Each mind became suffused with a vast,
immeasurable peace, calm power, and a depth and breadth of mental vision
theretofore undreamed of. Looking deep into his mind they sensed a
quiet, placid certainty, beheld power and knowledge to them illimitable,
perceived depths of wisdom to them unfathomable.

Then from his mind into theirs there flowed smoothly a mighty stream of
comprehension of cosmic phenomena. They hazily saw infinitely small
units grouped into planetary formations to form practically
dimensionless particles. These particles in turn grouped to form
slightly larger ones, and after a long succession of such grouping they
knew that the comparatively gigantic aggregates which then held their
attention were in reality electrons and protons, the smallest units
recognized by Earthly science. They clearly understood the combination
of these electrons and protons into atoms. They perceived plainly the
way in which atoms build up molecules, and comprehended the molecular
structure of matter. In mathematical thoughts, only dimly grasped even
by Seaton and Crane, were laid before them the fundamental laws of
physics, of electricity, of gravitation, and of chemistry. They saw
globular aggregations of matter, the suns and their planets, comprising
solar systems; saw solar systems, in accordance with those immutable
laws, grouped into galaxies, galaxies in turn--here the flow was
suddenly shut off as though a valve had been closed, and the astronomer
spoke.
