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
