"I would suggest that you do the same," advised Elfreda. "You need sleep and rest even more than we do. I hear Mrs. Gray telling our friends to prepare for bad weather, so I will run along and listen. Good-night, Mr. Lang."

The Overland girls, requested by Grace to turn in, after being told that a storm was in prospect, did so, but Hippy still remained up talking with Ping, who was scouring the cooking equipment and carefully stowing it in the packs so that it might all be in one place in the event that the storm was a severe one. Ping Wing had had experience with desert wind storms; he had learned to respect their tremendous force, and he too had read the danger signs in the heavens that night.

The guide being nowhere in sight, Hippy finally crawled into his tent and lay down with his clothes on, first, however, placing his revolver where it might be quickly reached in an emergency, but there was to be no use for his weapon that night. The enemy that he was to face later on would be proof against bullets, an enemy that no human courage, skill or ingenuity could stay.

Out by the water hole, Hi Lang sat keeping silent vigil, narrowly watching those film-mists overhead, his nerves on the alert to catch the first cooling breath, which he knew from past experience would be the vanguard of what he fully expected was in store for them.

CHAPTER X

WHEN THE BLOW FELL

A faint, cooling breath, wafted across the desert, fanned the cheek of Hi Lang. He inhaled deeply of it, not once, but several times.

"It is here!" he muttered, "I hope it may be a light one." Saying which the guide rose and walked briskly to the ponies' tethering ground. The animals were restive, they were stepping from side to side and an occasional snort was heard, but they quieted down when he went among them and spoke soothing words, petting an animal here, restaking another one there until he had spoken to each bronco in the outfit.

The guide's next move was to step to Hippy's tent and awaken him.

"What is it? Have the desert pirates returned?" questioned Hippy, sitting up and rubbing his eyes.
