a
feminine countenance, seen in profile, and possessing no small degree of
beauty. To my astonishment, this curious human semblance still remained
when we had approached so close to the moon that the mountains forming
the cape filled nearly the whole field of view of the window from which
I was watching it. The resemblance, indeed, was most startling.

The Resemblance Disappears.

"Can this indeed be Diana herself?" I said half aloud, but instantly
afterward I was laughing at my fancy, for Mr. Edison had overheard me
and exclaimed, "Where is she?"

"Who?"

"Diana."

"Why, there," I said, pointing to the moon. But lo! the appearance was
gone even while I spoke. A swift change had taken place in the line
of sight by which we were viewing it, and the likeness had disappeared
in consequence.

A few moments later my astonishment was revived, but the cause this
time was a very different one. We had been dropping rapidly toward the
mountains, and the electrician in charge of the car was swiftly and
constantly changing his potential, and, like a pilot who feels his way
into an unknown harbor, endeavoring to approach the moon in such a manner
that no hidden peril should surprise us. As we thus approached I suddenly
perceived, crowning the very apex of the lofty peak near the termination
of the cape, the ruins of what appeared to be an ancient watch tower. It
was evidently composed of Cyclopean blocks larger than any that I had
ever seen even among the ruins of Greece, Egypt and Asia Minor.

The Moon Was Inhabited.

Here, then, was visible proof that the moon had been inhabited, although
probably it was not inhabited now. I cannot describe the exultant feeling
which took possession of me at this discovery. It settled so much that
learned men had been disputing about for centuries.

"What will they say," I exclaimed, "when I show them a photograph
of that?"

Below the peak, stretching far to right and left, lay a barren beach
which had evidently once been washed by sea waves, because it was marked
by long curved ridges such as the advancing and retiring tide leaves
upon the shore of the ocean.

This beach sloped rapidly outward and downward toward a profound abyss,
which had once, evidently, been the bed of a sea, but which now appeared
to us simply as the empty, yawning shell of an ocean that had long
vanished.

It was with no small difficulty, and only after the expenditure of
considerable time, that all the
