Now below us, and now above us, for the ship had rolled completely over each time we had passed the point at which we came finally to rest, we had noted the luminosity that Norton had first observed from above the mouth of the crater. Each of us had been doing considerable thinking, and at last young Norton could contain himself no longer.
“I beg your pardon, sir,” he said deferentially, “but won’t you tell us what you think of it; what your theory is as to where we are and why we hang here in mid-air, and why the ship rolled over every time we passed this point?”
“I can only account for it,” I replied, “upon a single and rather preposterous hypothesis, which is that the Moon is a hollow sphere, with a solid crust some two hundred and fifty miles in thickness. Gravity is preventing us from rising above the point where we now are, while centrifugal force keeps us from falling.”
The others nodded. They too had been forced to accept the same apparently ridiculous theory, since there was none other that could explain our predicament. Norton had walked across the room to read the barometer which he had rather neglected while the ship had been performing her eccentric antics far below the surface of the Moon. I saw his brows knit as he glanced at it, and then I saw him studying it carefully, as though to assure himself that he had made no mistake in the reading. Then he turned toward us.
“There must be something wrong with this instrument, sir,” he said. “It is registering pressure equivalent to that at the Earth’s surface.”
I walked over and looked at the instrument. It certainly was registering the pressure that Norton had read, nor did there seem to be anything wrong with the instrument.
“There is a way to find out,” I said. “We can shut down the insulating generator and open an air-cock momentarily. It won’t take five seconds to determine whether the barometer is correct or not.” It was, of course, in some respects a risky proceeding, but with West at the generator, Jay at the air- cock and Norton at the pump I knew that we would be reasonably safe, even if there proved to be no atmosphere without. The only danger lay in the chance that we were hanging in a poisonous gas of the same density as the earthly atmosphere, but as there was no particular incentive to live in the situation in which we were, we each felt that no matter what chance we might take it would make little difference in the eventual outcome of our expedition.
I tell you that it was a very tense moment as the three men took their posts to await my word of command. If we had indeed discovered a true atmosphere beneath the surface of the Moon, what more might we not discover? If it were an atmosphere, we could propel the ship in it, and we could, if nothing more, go out on deck to breathe fresh air. It was arranged that at my word of command West was to shut off the generator. Jay to open the air-cock, and Norton to start the pump. If fresh air failed to enter through the tube Jay was to give the signal, whereupon Norton would reverse the pump, West start the generator, and immediately Jay would close the air-cock again.
As Jay was the only man who was to take a greater chance than the others, I walked over and stood beside him, placing my nostrils as close to the air- cock as his. Then I gave the word of command. Everything worked perfectly and an instant later a rush of fresh, cold air was pouring into the hull of The Barsoom. West and Norton had been watching the effects upon our faces closely, so that they knew almost as soon as we did that the result of our test had been satisfactory. We were all smiles, though just why we were so happy I am sure none of us could have told. Possibly it was just because we had found a condition that was identical with an earthly condition, and though we might never see our world again we could at least breathe air similar to hers. I had them start the motors again then, and presently we were moving in a great spiral upward toward the interior of the Moon. Our progress was very slow, but as we rose the temperature rose slowly, too, while the barometer showed a very- slightly-decreasing atmospheric pressure. The luminosity, now above us, increased as we ascended, until finally the sides of the great well through which we were passing became slightly illuminated.
All this time Orthis had remained in irons in his stateroom. I had given instructions that he was to be furnished food and water, but no one was to speak to him, and I had taken Norton into my stateroom with me. Knowing Orthis to be a drunkard, a traitor and a potential murderer I had no sympathy whatsoever for him. I had determined to court-martial him and did not intend to spend the few remaining hours or years of my life cooped up in a small ship with him, and I knew that the verdict of any court, whether composed of the remaining crew of The Barsoom, or appointed by the Judge Advocate General of the Navy, could result in but one thing, and that was death for Orthis. I had left the matter, however, until we were not pressed with other matters of greater importance, and so he still lived, though he shared neither in our fears, our hopes, nor our joys.
About twenty-six hours after we entered the mouth of the crater at the surface of the Moon we suddenly emerged from its opposite end to look upon a scene that was as marvelous and weird, by comparison with the landscape upon the surface of the Moon, as the latter was in comparison with that of our own Earth. A soft, diffused light revealed to us in turn mountains, valleys and sea, the details of which were more slowly encompassed by our minds. The mountains were as rugged as those upon the surface of the satellite, and appeared equally as lofty. They were, however, clothed with verdure almost to their summits, at least a few that were within our range of vision. And there were forests, too — strange forests, of strange trees, so unearthly in appearance as to suggest the weird phantasmagoria of a dream.
We did not rise much above five hundred feet from the opening of the well through which we had come from outer space when I descried an excellent landing place and determined to descend. This was readily accomplished, and we made a safe landing close to a large forest and near the bank of a small stream. Then we opened the forward hatch and stepped out upon the deck of The Barsoom, the first Earth Men to breathe the air of Luna. It was, according to Earth time, eleven A.M., January 8, 2026.
I think that the first thing which engaged our interest and attention was the strange, and then, to us, unaccountable luminosity which pervaded the interior of the Moon. Above us were banks of fleecy clouds, the undersurfaces of which appeared to be lighted from beneath, while, through breaks in the cloud banks we could discern a luminous firmament beyond, though nowhere was there any suggestion of a central incandescent orb radiating light and heat as does our sun. The clouds themselves cast no shadows upon the ground, nor, in fact, were there any well-defined shadows even directly beneath the hull of the ship or surrounding the forest trees which grew close at hand. The shadows were vague and nebulous, blending off into nothingnesses at their edges. We ourselves cast no more shadows upon the deck of The Barsoom than would have been true upon a cloudy day on Earth. Yet the general illumination surrounding us approximated that of a very slightly hazy Earth day. This peculiar lunar light interested us profoundly, but it was some time before we discovered the true explanation of its origin. It was of two kinds, emanating from widely different sources, the chief of which was due to the considerable radium content of the internal lunar soil, and principally of the rock forming the loftier mountain ranges, the radium being so combined as to diffuse a gentle perpetual light which pervaded the entire interior of the Moon. The secondary source was sunlight, which penetrated to the interior of the Moon through the hundreds of thousands of huge craters penetrating the lunar crust. It was this sunlight which carried heat to the inner world, maintaining a constant temperature of about eighty degrees Fahrenheit.
Centrifugal force, in combination with the gravity of the Moon’s crust, confined the internal lunar atmosphere to a blanket which we estimated at about fifty miles in thickness over the inner surface of this buried world. This atmosphere rarefies rapidly as one ascends the higher peaks, with the result that these are constantly covered with perpetual snow and ice, sending great glaciers down mighty gorges toward the central seas. It is this c
ondition which has probably prevented the atmosphere, confined as it is within an almost solid sphere, from becoming superheated, through the unthinkable ages that this condition must have existed. The Earth seasons are reflected but slightly in the Moon, there being but a few degrees difference between summer and winter. There are, however, periodic wind-storms, which recur with greater or less regularity once each sidereal month, due, I imagine, to the unequal distribution of crater openings through the crust of the Moon, a fact which must produce an unequal absorption of heat at various times and in certain localities. The natural circulation of the lunar atmosphere, affected as it is by the constantly-changing volume and direction of the sun’s rays, as well as the great range of temperature between the valleys and the ice-clad mountain peaks, produces frequent storms of greater or less violence. High winds are accompanied by violent rains upon the lower levels and blinding snowstorms among the barren heights above the vegetation line. Rains which fall from low- hanging clouds are warm and pleasant; those which come from high clouds are cold and disagreeable, yet however violent or protracted the storm, the illumination remains practically constant — there are never any dark, lowering days within the Moon, nor is there any night.
3. ANIMALS OR MEN?
Of course we did not reach all these conclusions in a few moments, but I have given them here merely as the outcome of our deductions following a considerable experience within the Moon. Several miles from the ship rose foothills which climbed picturesquely toward the cloudy heights of the loftier mountains behind them, and as we looked in the direction of these latter, and then out across the forest, there was appreciable to us a strangeness that at first we could not explain, but which we later discovered was due to the fact that there was no horizon, the distance that one could see being dependent solely upon one’s power of vision. The general effect was of being in the bottom of a tremendous bowl, with sides so high that one might not see the top.
The ground about us was covered with rank vegetation of pale hues - lavenders, violets, pinks and yellows predominating. Pink grasses which became distinctly flesh-color at maturity grew in abundance, and the stalks of most of the flowering plants were of this same peculiar hue. The flowers themselves were often of highly complex form, of pale and delicate shades, of great size and rare beauty. There were low shrubs that bore a berry-like fruit, and many of the trees of the forest carried fruit of considerable size and of a variety of forms and colors. Norton and Jay were debating the possible edibility of some of these, but I gave orders that no one was to taste them until we had had an opportunity to learn by analysis or otherwise those varieties that were non- poisonous.
There was aboard The Barsoom a small laboratory equipped especially for the purpose of analyzing the vegetable and mineral products of Mars according to earthly standards, as well as other means of conducting research work upon our sister planet. As we had sufficient food aboard for a period of fifteen years, there was no immediate necessity for eating any of the lunar fruit, but I was anxious to ascertain the chemical properties of the water since the manufacture of this necessity was slow, laborious and expensive. I therefore instructed West to take a sample from the stream and subject it to laboratory tests, and the others I ordered below for sleep.
They were rather more keen to set out upon a tour of exploration, nor could I blame them, but as none of us had slept for rather better than forty- eight hours I considered it of importance that we recuperate our vital forces against whatever contingency might confront us in this unknown world. Here were air, water and vegetation — the three prime requisites for the support of animal life — and so I judged it only reasonable to assume that animal life existed within the Moon. If it did exist, it might be in some highly predatory form, against which it would tax our resources to the utmost to defend ourselves. I insisted, therefore, upon each of us obtaining his full quota of sleep before venturing from the safety of The Barsoom.
We already had seen evidences of life of a low order, both reptile and insect, or perhaps it would be better to describe the latter as flying reptiles, as they later proved to be — toad-like creatures with the wings of bats, that flitted among the fleshy boughs of the forest, emitting plaintive cries. Upon the ground near the ship we had seen but a single creature, though the moving grasses had assured us that there were others there aplenty. The thing that we had seen had been plainly visible to us all and may be best described as a five-foot snake with four frog-like legs, and a flat head with a single eye in the center of the forehead. Its legs were very short, and as it moved along the ground it both wriggled like a true snake and scrambled with its four short legs. We watched it to the edge of the river and saw it dive in and disappear beneath the surface.
“Silly looking beggar,” remarked Jay, “and devilish unearthly.”
“I don’t know about that,” I returned. “He possessed nothing visible to us that we are not familiar with on Earth. Possibly he was assembled after a slightly different plan from any Earth creature; but aside from that he is familiar to us, even to his amphibious habits. And these flying toads, too; what of them? I see nothing particularly remarkable about them. We have just as strange forms on Earth, though nothing precisely like these. Mars, too, has forms of animal and vegetable life peculiar to herself, yet nothing the existence of which would be impossible upon Earth, and she has, as well, human forms almost identical with our own. You see what I am trying to suggest?”
“Yes, sir,” replied Jay; “that there may be human life similar to our own within the Moon.”
“I see no reason to be surprised should we discover human beings here,” I said; “nor would I be surprised to find a reasoning creature of some widely divergent form. I would be surprised, however, were we to find no form analogous to the human race of Earth.”
“That is, a dominant race with well developed reasoning faculties?” asked Norton.
“Yes, and it is because of this possibility that we must have sleep and keep ourselves fit, since we may not know the disposition of these creatures, provided they exist, nor the reception that they will accord us. And so, Mr. Norton, if you will get a receptacle and fetch some water from the stream we will leave Mr. West on watch to make his analysis and the rest of us will turn in.”
Norton went below and returned with a glass jar in which to carry the water and the balance of us lined the rail with our service revolvers ready in the event of an emergency as he went over the side. None of us had walked more than a few steps since coming on deck after our landing. I had noticed a slightly peculiar sensation of buoyancy, but in view of the numerous other distractions had given it no consideration. As Norton reached the bottom of the ladder and set foot on lunar soil I called to him to make haste. Just in front of him was a low bush and beyond it lay the river, about thirty feet distant. In response to my command he gave a slight leap to clear the bush and, to our amazement as well as to his own consternation, rose fully eighteen feet into the air, cleared a space of fully thirty-five feet and lit in the river.
“Come!” I said to the others, wishing them to follow me to Norton’s aid, and sprang for the rail; but I was too impetuous. I never touched the rail, but cleared it by many feet, sailed over the intervening strip of land, and disappeared beneath the icy waters of the lunar river. How deep it was I do not know; but at least it was over my head. I found myself in a sluggish, yet powerful current, the water seeming to move much as a heavy oil moves to the gravity of Earth. As I came to the surface I saw Norton swimming strongly for the bank and a second later Jay emerged not far from me. I glanced quickly around for West, whom I immediately perceived was still on the deck of The Barsoom, where, of course, it was his duty to remain, since it was his watch.
The moment that I realized that my companions were all safe I could not repress a smile, and then Norton and Jay commenced to laugh, and we were still laughing when we pulled ourselves from the stream a short distance below the ship.
“Get your sample, Norton?” I ask
ed.
“I still have the container, sir,” he replied, and indeed he had clung to it throughout his surprising adventure, as Jay and I, fortunately, had clung to our revolvers. Norton removed the cap from the bottle and dipped the latter into the stream. Then he looked up at me and smiled.
“I think we have beaten Mr. West to it, sir,” he said. “It seems like very good water, sir, and when I struck it I was so surprised that I must have swallowed at least a quart.”
“I tested a bit of it myself,” I replied. “As far as we three are concerned, Mr. West’s analysis will not interest us if he discovers that lunar water contains poisonous matter, but for his own protection we will let him proceed with his investigation.”
“It is strange, sir,” remarked Jay, “that none of us thought of the natural effects of the lesser gravity of the Moon. We have discussed the matter upon many occasions, as you will recall, yet when we faced the actual condition we gave it no consideration whatsoever.”
“I am glad,” remarked Norton, “that I did not attempt to jump the river - I should have been going yet. Probably landed on the top of some mountain.”
As we approached the ship I saw West awaiting us with a most serious and dignified mien; but when he saw that we were all laughing he joined us, telling us after we reached the deck, that he had never witnessed a more surprising or ludicrous sight in his life.
We went below then and after closing and securing the hatch, three of us repaired to our bunks, while West with the sample of lunar water went to the laboratory. I was very tired and slept soundly for some ten hours, for it was the middle of Norton’s watch before I awoke.
The only important entry upon the log since I had turned in was West’s report of the results of his analysis of the water, which showed that it was not only perfectly safe for drinking purposes but unusually pure, with an extremely low saline content.
