"And why did you come?" she asked him. "Nay—I would have him speak for himself, if he can," she stilled Marakinoff peremptorily.

When Larry spoke it was haltingly, in the tongue that was strange to him, searching for the proper words.

"I came to help these men—and because something I could not then understand called me, O lady, whose eyes are like forest pools at dawn," he answered; and even in the unfamiliar words there was a touch of the Irish brogue, and little merry lights danced in the eyes Larry had so apostrophized.

"I could find fault with your speech, but none with its burden," she said. "What forest pools are I know not, and the dawn has not shone upon the people of Lora these many sais of laya.[1] But I sense what you mean!"

The eyes deepened to blue as she regarded him. She smiled.

"Are there many like you in the world from which you come?" she asked softly. "Well, we soon shall—"

Lugur interrupted her almost rudely and glowering.

"Best we should know how they came hence," he growled.

She darted a quick look at him, and again the little devils danced in her wondrous eyes.

[Unquestionably there is a subtle difference between time as we know it and time in this subterranean land—its progress there being slower. This, however, is only in accord with the well-known doctrine of relativity, which predicates both space and time as necessary inventions of the human mind to orient itself to the conditions under which it finds itself. I tried often to measure this difference, but could never do so to my entire satisfaction. The closest I can come to it is to say that an hour of our time is the equivalent of an hour and five-eighths in Muria. For further information upon this matter of relativity the reader may consult any of the numerous books upon the subject.—W. T. G.]
