“I don't know.” Tradmos looked out at the window for a moment as if to ascertain that they were going in the right direction, then he fixed his dark eyes on Thorndyke and asked hesitatingly:—

“I never thought—I—but do you know where your country is located?”

“Why, certainly.”

“Well, I don't know where this one is. We are taught everything, I think, except geography.” Nothing more was said for several minutes, then an exclamation of admiration broke from the Englishman. The color of the sunlight was changing. From east to west within the entire arc of their observation rolled an endless billow of lavender light leaving a placid sea of the same color behind it. On it swept, slowly driving back the pink glow that had been over everything.

“I see you like our sunlight?” said Tradmos, half interrogatively.

“Never saw anything like it before.”

“Yours is, I think, the same color all day long.”

“Except on rainy days.”

“Must be a great bore, monotonous—too much sameness. It is white, is it not?”

“Yes, rather—between white and yellow, I call it.”
