y valuable for its
intrinsic worth by your own standards, but to us the value of the dome
lies in its function in revealing to us the past and present events of
our universe. The dome is the 'eye' of a complicated apparatus which
enables us to see and hear any desired happening on the surface of the
earth, beneath its surface, or on the many inhabited planets of the
heavens. This is accomplished by means of extremely complex vibrations
radiated from the hemisphere, these vibrations penetrating earth,
metals, buildings, space itself, and returning to our viewing and
sound reproducing spheres to reveal the desired past or present
occurrences at the point at which the rays of vibrations are directed.

"In order to view the past on our own planet, the rays, which travel
at the speed of light, are sent out in a huge circle through space,
returning to earth after having spent the requisite number of years in
transit. Instantaneous effect is secured by a connecting beam that
ties together the ends of the enormous arc. This, of course, is beyond
your comprehension, since the Ninth Dimension is involved. When it is
desired that events of the present be observed, the rays are projected
direct. The future can not be viewed, since, in order to accomplish
this, it would be necessary that the rays travel at a speed greater
than that of light, which is manifestly impossible."

"Great guns!" gasped Frank. "This crystal sphere then, is capable of
bringing to our eyes and ears the happenings of centuries past?"

"It is, my dear Frank," said Phaestra, "and I would that I were able
to describe the process more clearly." She smiled, and in the
unearthly light of the sphere she appeared more beautiful than before,
if such a thing were possible.

On the pedestal which supported the sphere there was a glittering
array of dials and levers. Several of these controls were now adjusted
by Phaestra, the delicate motions of her tapered fingers being watched
by the visitors with intense admiration. There came a change in the
note of the sphere, a steadying of the flickerings within.

"Behold!" exclaimed Phaestra.

They gazed into the depths of the sphere and lost all sense of
detachment from the scene depicted therein. It seemed they were at a
point several thousand miles from the surface of a planet. A great
continent spread beneath them, its irregular shore
