…But we are DETERMINED before the column ends to ask you what you think of our moon-earth-sun transmigration notion. The sun is now a blazing mass, inconceivably huge, inconceivably fierce in our eyes. Its flames leap hundreds of thousands of miles into space. If our earth fell to the sun, it would melt as a snowflake falling upon a blazing forest. We certainly do not readily look upon the sun as our future home, if we accept its present condition as permanent. But once upon a time, hundreds of millions of years back, this earth used to look TO THE MOON, on a smaller scale, as the sun now looks to us. If there were on the moon at that time inferior human beings, in a low state of cosmic evolution, they undoubtedly had to thank the earth for their life, as we thank the sun. To them the earth, then incandescent, blazing with the heat that now reveals itself through volcanoes, was simply a whirling ball of fire, put in its place to warm them. They could no more think that men would ever come to live here than we can now think of moving on to the sun. In course of time this earth cooled off. It cooled so thoroughly that the moon died of cold. Life could no longer continue there. The dead satellite's destiny thenceforward was to show gratitude for past heat by moving our tides and cheering our poets. As life died out on the cold moon which had given us temporary hospitality, life sprang into being on this planet, now fitted to support it. Here, on a larger sphere, with greater opportunities, mankind is growing, and will far outstrip all that it could have done on the poor little moon. Meanwhile, as we struggle on, improving slowly, the sun, as science proves, is cooling off in its turn. The flames become less fierce as the thousands of centuries roll by. When we shall have developed as much as possible on this limited planet, our home will be cooled and ready on the sun, centre of our life in this corner of space. We shall move up a step—as boys do in the public schools. We shall have been moon men, earth men, and shall graduate into sun men. Think of a home so vast! On that grand star we shall lead lives worth while, and justify Huxley's belief that men exist somewhere compared to whom we should "be as black beetles compared to us." The excitement of meeting our brothers from other planets as they move up to the sun in batches will be great.
