She said it cheerfully, but firmly, a sleepy, sunburned little nomad, sitting cross-legged in the sands, slowly plaiting her honey-colored hair. "Even this," she announced, indicating the slight gesture of braiding, "is agony."

"It's the morning after," said Billy, testing his shoulder with wry grimaces. "It's yesterday's speed—and then this infernally cold night. No wonder we're lame. Why, I have one universal crick wherever I used to have muscles. But let me call your attention to the fact that we are in the wilds of Egypt and that tangerines are hardly a lasting breakfast. Something has to be done."

"Not upon camels," said Arlee fixedly.

"They say it doesn't hurt after an hour or so more."

"I shouldn't live to find out."

"A walk," he suggested, "a slow, swaying, gently undulating walk——?"

"A long, lingering, agonizing death," the young lady translated. She tossed the curly end of her braid over her shoulder and rose, with sounds of lamentation. "I ought to have known better than to sit down again when I was once up," she confided sadly.

"Just what," inquired her companion, "is your idea for the day? How do you expect to reach Girgeh? It can't be very far away now——"

"Then we'll walk—we'll walk," she emphasized, "and tow those ships of the desert after us. That will be bad enough, but better—what's that?"

Like a top, for all his stiffness, Billy spun about to stare where her finger pointed. Over the crest of a hillock, far to the north—yes, something was hurrying their way.
