On that theory they would have grown innumerable some Eight Hundred Thousand Years hence, and it was no great wonder to see four at once. But the jest was unsatisfying, and I was thinking of these figures all the morning, until Weena's rescue drove them out of my head. I associated them in some indefinite way with the white animal I had startled in my first passionate search for the Time Machine. But Weena was a pleasant substitute.

"I think I have said how much hotter than our own was the weather of this Golden Age. I cannot account for it. It may be that the sun was hotter, or the earth nearer the sun. It is usual to assume that the sun will go on cooling steadily in the future. But people, unfamiliar with such speculations as those of the younger Darwin, forget that the planets must ultimately fall back one by one into the parent body.
