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 fact, I was informed that for several hours the squadron had been dragging along in the wake of a comet, very much as boats are sometimes towed off by a wounded whale. Every effort had been made to so adjust the electric charge upon the ships that they would be repelled from the cometic mass, but, owing apparently to electric changes affecting the clashing mass of meteoric bodies which constituted the head of the comet, we found it impossible to escape from its influence. At one instant the ships would be repelled; immediately afterward they would be attracted again, and thus they were dragged hither and thither, but never able to break from the invisible leash which the comet had cast upon them. The latter was moving with enormous velocity toward the sun, and, consequently, we were being carried back again, away from the object of our expedition, with a fair prospect of being dissipated in blazing vapors when the comet had dragged us, unwilling prisoners, into the immediate neighborhood of the solar furnace. Even the most cool-headed lost his self control in this terrible emergency. Every kind of devise that experience or the imagination could suggest was tried, but nothing would do. Still on we rushed with the electrified atoms composing the tail of the comet swinging to and fro over the members of the squadron, as they shifted their position, like the plume of smoke from a gigantic steamer, drifting over the sea birds that follow in its course. Was this to end it all, then? Was this the fate that Providence had in store for us? Were the hopes of the earth thus to perish? Was the expedition to be wrecked and its fate to remain for ever unknown to the planet from which it had set forth? And was our beloved globe, which had seemed so fair to us when we last looked upon it nearby, and in whose defense we had resolved to spend our last breath, to be left helpless and at the mercy of its implacable foe in the sky?
