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.”
