y means of
oscillating currents.

Soon upon the hillside, perfectly arranged and adjusted, appeared a
giant, parabolic, refracting mirror with which he could obtain a view of
any portion of the earth's surface by sending vibrating currents around
the world and reproducing impressions already recorded on the ether, on
the surface of the mirror. And beneath its center was a receiver,
through which he might have heard the minutest sound around the world,
had there been any to hear.

The small, atomic motors--which drew their energy both from hydrogen
nuclei, the ether of space and the radio-active substances of all
metals--now were placed on the hillside near the great mirror. There
motors were capable of creating and focusing light, without bulb or
other container, whenever and wherever needed. All were operated with
scarcely any effort by Omega.

In a measure it seemed strange that the Greek alphabet and all the
classics of the ancients had survived antiquity. But the latest
inventions of man explained it all. For man with his machines had
reached far back into the shadowy past and proved the immortality of all
thought and action. All the records of history, all the triumphs and
defeats, the joys and sorrows and aspirations of humanity, came out of
the past and marched across the screen of his historical recorder. As
nothing is ever lost, all sounds and impressions occurring on earth
since the dawn of its creation, being already impressed on the sensitive
plastic and all-pervading ether, the same as a photograph is recorded on
its film or plate, man had developed a machine for drawing on these
impressions until at will the history of the world was before him. Even
the varied life of the ancients came out of the past. Saints and
sinners, slaves and masters mingled. Confucius sat before him in
humility; Guatama counseled his followers to be humble; Christ died upon
the cross. Warriors and statesmen shouted their triumphs and bewailed
their defeats. Philosophers expounded their wisdom and Socrates drank
the hemlock. Hannibal and Caesar and Alexander fought their battles,
and Napoleon marched gory and unafraid from Austerlitz to Waterloo. All
came back at the call of Omega's science.

As has been stated it was a giant craft on which Omega and Thalma had
come to this last retreat of man. Within its interior were all the
latest marvels of man's ingenuity and skill. These instrume
