In the mean time, the repairs to the electrical ships had been completed, and, although these discoveries upon the moon had created a most profound sensation among the members of the expedition, and aroused an almost irresistible desire to continue the explorations thus happily begun, yet everybody knew that these things were aside from the main purpose in view, and that we should be false to our duty in wasting a moment more upon the moon than was absolutely necessary to put the ships in proper condition to proceed on their warlike voyage. Departing from the Moon. Everything being prepared then, we left the moon with great regret, just forty-eight hours after we had landed upon its surface, carrying with us a determination to revisit it and to learn more of its wonderful secrets in case we should survive the dangers which we were now going to face. Chapter VI. A day or two after leaving the moon we had another adventure with a wandering inhabitant of space which brought us into far greater peril than had our encounter with the meteor. The airships had been partitioned off so that a portion of the interior could be darkened in order to serve as a sleeping chamber, wherein, according to the regulations prescribed by the commander of the squadron each member of the expedition in his turn passed eight out of every twenty-four hours--sleeping if he could, if not, meditating, in a more or less dazed way, upon the wonderful things that he was seeing and doing--things far more incredible than the creations of a dream. One morning, if I may call by the name morning the time of my periodical emergence from the darkened chamber, glancing from one of the windows, I was startled to see in the black sky a brilliant comet. The Adventure With The Comet. A Thrilling Story of an Encounter that Nearly Ended the Great Expedition. No periodical comet, as I knew, was at this time approaching the neighborhood of the sun, and no stranger of that kind had been detected from the observatories making its way sunward before we left the earth. Here, however, was unmistakably a comet rushing toward the sun, flinging out a great gleaming tail behind it and so close to us that I wondered to see it remaining almost motionless in the sky. This phenomenon was soon explained to me, and the explanation was of a most disquieting character. The stranger had already been perceived, not only from the flagship, but from the other members of the squadron, and, as I now learned, efforts had been made to get out of the neighborhood, but for some reason the electrical apparatus did not work perfectly--some mysterious disturbing force acting upon it--and so it had been found impossible to avoid an encounter with the comet, not an actual coming into contact with it, but a falling into the sphere of its influence. In the Wake of the Comet.
