"I never saw one," admitted Barton without shame.

"If you'd like me to," said Eve, "I'll show you how the turquoise-colored waves sound—when they strike the hermit-crabs."

"Do!" urged Barton.

Listlessly the girl pushed back into her pillows, slid down a little farther into her blankets, and closed her eyes.

"Mmmmmmmmm," she began, "Mmm-mmmmmmm—Mmmmm—Mmmmmmm, W-h-i-s-h-h-h! Mmmmmmmmm—Mmmmmmmm—Mmmmmmmm—Mmmmmm—W-h-i-s-h-h-h!—Mmmmmmmm—Mmmmmmm—"

"After a while, of course, I think you might stop," suggested Barton a bit creepishly.

Again the big eyes opened at him with distinct surprise. "Why—why?" said Eve Edgarton. "It—never stops!"

"Oh, I say," frowned Barton, "I do feel awfully badly about your going away off to a place like that to live! Really!" he stammered.

"We're going—Thursday," said little Eve Edgarton.
