Book Two Beyond the Great Oblivion Chapter 9 Planning the Great Migration

They both pondered a while, absorbed in wonder. At last the engineer spoke again.

"Beta," said he, "there's another curious fact to note. The axis of the earth itself has shifted more than six degrees, thirty minutes!"

"It has? Well--what about it?" And she went on with her platting of reed cordage.

"You don't seem much concerned about it!"

So far as practical results go, it accounts for the warmer climate and the decreased inclination to the plane of the ecliptic; or, rather, the decreased--"

"Well, that depends on how you define it. Probably an astronomer might think there was something very much wrong. I make it that the orbit of the earth has altered its relative length and width by--"

For another thing, I'm convinced by all these changes, and by the diminution of gravity and by the accelerated rate of revolution of the earth--"
