I may say that I had been somewhat familiar with the scenery of this part of the lunar world, for I had often studied it from the earth with a telescope, and I had thought that if there was any part of the moon where one might, with fair expectation of success, look for inhabitants, or if not inhabitants, at least for relics of life no longer existant there, this would surely be the place. It was, therefore, with no small degree of curiosity, notwithstanding the unexpectedly frightful and repulsive appearance that the surface of the moon presented, that I now saw myself rapidly approaching the region concerning whose secrets my imagination had so often busied itself. When Mr. Edison and I had paid our previous trip to the moon on our first experimental trip of the electrical ship we had landed at a point on its surface remote from this, and, as I have before explained, we then made no effort to investigate its secrets. But now it was to be different, and we were at length to see something of the wonders of the moon. I had often on the earth drawn a smile from my friends by showing them Cape Heraclides with a telescope, and calling their attention to the fact that the outline of the peak terminating the cape was such as to present a remarkable resemblance to a human face, unmistakably 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. "Can this indeed be Diana herself?" I said half-aloud, but instantly afterward I was laughing at my fancy, for Mr. Edison had overhead 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.
