“On account of the smaller volume of the moon, the attraction of gravitation on its surface is only one-quarter that of the earth, and it is estimated that, if a projectile were hurled from the moon with two or three times the velocity of a cannon ball, it would pass entirely beyond her attraction and be drawn to the earth, reaching it at the rate of some seven miles a second.
“Now we all know—this is the way the story runs—that the moon was once inhabited by a highly intelligent race. They tell us it is a cold, dead world now, not at all fit for inhabitants. But that is because its day is passed. Being so much smaller than the earth it cooled off quicker, and its life-bearing period long since found its end. Men have often speculated on the idea that our race will one day fail and the time come when the last generation shall pass away and leave the earth a bare and ugly thing, to continue yet longer its lonely, weary journey around a failing sun. That day the moon has seen. That direful fate the race of moon men have experienced. Some poor being, the last of his kind, was left sole monarch of a dying world, and with the moon all before him where to choose, chose rather to die with the rest and leave his world to cold and darkness.
“From our own experience we do not know how high a state of civilization can be reached by giving a race all the time that is needed. But we know that before the inhabitants of the moon passed off the stage they had attained to the highest possible degree of intelligence. They began existence at a very low plane, developed gradually through long periods of time—there has never been any haste in these matters—and when they had reached their maturity as a race of intellectual and moral beings, primitive man was just beginning on the vast undertaking of subduing the earth, a task not yet accomplished.
“The incident I propose to relate occurred in antediluvian times, when there were giants in the earth who lived a thousand years. Then matter reigned, not mind. It was the age of brawn. Everything material existed on a gigantic scale, and man’s architectural works, rude in design but well adapted for shelter and protection, were proportioned to his own stature and rivaled the everlasting hills in size and solidity. And they needed something substantial for protection, for war was their business and their pass time. They lived for nothing but to fight. It was brother against brother, neighbor against neighbor, tribe against tribe; and the man who could not fight, and fight hard, had no excuse for living. War was not an art, but a natural outburst of brutal instincts. A giant glories in his strength and cultivates it as naturally as a bird its song. But it is pleasant to consider the fact that as man’s mental and moral qualities have developed his body has become smaller. As the necessity for that immense physical strength gradually passed away, nature, abhorring such unnecessary waste of material, applied to us her inexorable laws whereby a thing or a state of things no longer useful slowly fades away, and our bodies accommodated themselves to new conditions.
“But in those early times men needed great physical strength and long life to bring the world into subjection, and until that was done they could give little attention to the cultivation of the finer qualities of their incipient manhood. They were handicapped by the fact that the lower animals had had the earth to themselves a few million years, more or less, and no puny race could ever have driven them to the wall.
“At length, when the conflict was well nigh over, with victory in sight, men had abandoned the struggle and were using all their fierce strength in fighting each other. This had been going on so long and with such deadly results that it seemed as if the race must be exterminated unless some superior power could step in from the outside and prevent it.
“We can easily understand that there was no such thing as science then. Men considered the sun, for example, only as a very useful thing which brought them light with which they could see their foe, and the moon as a mysterious object sent to make the night a little less dark. Sun and moon and shining stars were all set in the sky for them, and went through their wonderful and complicated movements solely for their amusement.
“But what was the real condition of things on the moon at that time? Why, there was a race of people there of such intelligence and scientific attainments that they were seeing plainly enough everything that was taking place on the earth. This will not appear very strange when we consider our remarkable success in scanning the surface of the moon at the present day, and remember that the inhabitants of the moon were then nearing the close of their history, and so at the height of their civilization.
“Yes, they had watched the coming of man upon the stage with the deepest interest—with a neighborly interest, in fact—seeing in him the promise of a companion race and one worthy of the magnificent globe which they could see was so much larger than their own. Their powerful instruments enabled them to see objects on the earth as distinctly as we now see through our telescopes the features of a landscape a few miles distant.
“Keeping thus so close an acquaintance with man and all his works, they rejoiced at every success he achieved over the lower forms of life, and grieved at all his failures. Especially were they pained when he tired of the conflict with his natural foe, and began to battle with his own kind. As this inhuman strife continued, the folly and wickedness of it roused to the fullest extent the interest and sympathy of the moon-dwellers, and they began to ask each other what they could do to put a stop to it. They themselves had long since given up war and had even outgrown all individual quarrels, and they could not endure with patience what was then taking place right under their eyes. But they found it easier to declaim against the evil than to suggest any practical method of stopping it. Although so near them in one sense, to the other senses the field of conflict was some two hundred and forty thousand miles away.
