Our starting place was far enough from the resting point of the moon to enable us to clear the rounded side, but in order to reach the equatorial line of the fallen globe we would be obliged to ascend over a thousand miles.
The fact that we were not appalled by the mere thought of rising to such a height shows how thoroughly we were carried away with the excitement. But we were better prepared for a lofty flight than might be supposed. For among the recent wonders of science had been the invention of an air-condensing machine, by which the rarefied atmosphere of the upper regions could be converted into good food for the lungs. These machines had been successfully tested more than once by voyagers of the air, but the present occasion promised to give them a much more severe trial than they had yet received. And, indeed, it is impossible to imagine how we could have survived without them. Another important aid to science rendered by this air-condensing apparatus is that in the process of condensation water is produced in sufficient quantities to drink. Our little car was tightly inclosed, and we took enough surplus gas with us to keep it comfortably warm. So, with plenty of food, air, water, and fuel, we were pretty well prepared for a long journey.
Our instruments, placed just outside the glass sides of the car, told us how fast we were rising and what height we had reached from time to time, and as we left the denser atmosphere of the earth we were gratified to find that we continued to rise rapidly. On one side of us we could see the rugged surface of the moon, now, on account of its rounded form, drawing nearer to us every hour as we approached the point where we hoped to land. We thought it best to try to pass the center and land, if possible, somewhere on the upper hemisphere, which was the part of the monstrous object that we wanted to investigate. But when at length we thought we were about to fly past the moon’s equator successfully, an unexpected thing happened.
If we suppose the moon was resting, at the bottom of the ocean, on one of its poles, we were going toward the equatorial line, and we thought we should not be able to retain a foothold anywhere below that line certainly. But now, what was our surprise to find ourselves under some mysterious influence. Our balloon refused to obey us as heretofore, and in spite of rudder and sail we were drifting about, and appeared to be going toward the moon’s surface sooner than we had intended.
In scientific emergencies I deferred to my companion, and now asked for an explanation of this erratic behavior of our balloon. Instead of replying at once, the doctor stooped and cut a fine wire, which released one of the sand bags suspended for ballast from the bottom of our car, and told me to watch it. We both watched it, and instead of starting with rapidity for the center of the earth, as all well-conducted sand bags have done from the beginning of the world, it seemed to hesitate and float around a minute, as though it were no more than a handful of feathers. And then, slowly at first, but soon more and more swiftly, forgetting its birthplace and its old mother earth, it fell unblushingly toward the moon.
Intent on watching the fickle sand bag, we did not at first notice that our whole conveyance was practicing the same unhandsome maneuver. But we soon became aware that we had changed allegiance also. We had started with the earth at our feet and the moon looming up on one side of us, but here we were now riding with the moon under us and the earth away off at our side.
My fellow in this strange experience now found his voice.
“You doubtless realize,” said he, “what has taken place. We are now so far from the earth that its attraction is very weak and the nearer mass of the moon is drawing us.”
“That is quite evident,” I said, “but you seem as unconcerned about it as if such a trip as this were an everyday affair with you.”
“I am not at all indifferent to the wonderful character of this journey,” he replied, “but its scientific value swallows up all personal considerations.”
