So they're moving northwards to Chicago on p. 1.

Then on p. 9, this discussion:

"Here it is in a nutshell," Randolph confided later.  "Going up is like going north."  He stood blinking, as if expecting a comment.
"But," it occurred to Chick, if you keep going far enough north, eventually you pass over the Pole, and then you're heading south again."
"Yes."  The skyship commander shrugged uncomfortably.
"So ... if you went up high enough, you'd be going down again?"
"Shh! warned Randolph St. Cosmo.

This actually reminds me of the mathematical novel Flatland.  The two-dimensional protagonist tries to convince his countrymen that there are three dimensions with the slogan "upward, not northward."
