"Turn out!" Hippy yawned and got up. The night was now pitch dark, and Lieutenant Wingate fell over tent stakes and ropes and whatever else was handy for him to catch his toes on, as he staggered about aimlessly.

Bethinking himself of the guide's orders, Hippy suddenly began pulling up the stakes from the girls' tent and let it down on their heads. Emma Dean cried out, which brought a stern command for silence from Mr. Lang. Following that, there was not a sound in the camp during the next fifteen minutes.

"Packs lashed to ponies behind saddles," announced Hippy. "Party ready to move."

"Mount and follow me. No loud talking, please; light no matches. You understand why I am so strict?" said the guide in an apologetic tone.

"We understand fully, Mr. Lang," replied Grace in a low voice.

"Start!" he commanded.

The start was made at a jog-trot, which, after a few minutes, was changed to a gallop. This pace was continued for some time, but finally the guide slowed down and began peering into the darkness, looking for Ping and his burros. Elfreda marveled at the almost uncanny instinct of their guide, and how Ping could lay a course that could be followed in the dark was a mystery to her. She asked Hi Lang how it was done.

"See that red star over on the horizon, Miss Briggs? Ping is instructed to keep that star between the ears of his burro and not to wobble. By keeping the same star between the ears of my bronco I am bound to overhaul Ping, provided he has held to his course. I am, however, allowing for some deviation and keeping a close lookout."

It was not more than ten minutes after that when Mr. Lang discovered the Chinaman and his burden bearers plodding along less than a hundred yards to the right of the course that the Overland Riders were following. Ping, though he had heard the party coming up, held to his course until directed to fall in behind them.

"A mariner following a compass course could do no better than that," declared Grace Harlowe.
