“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.
