CHAPTER III
ARAB RAIDERS
Dan came running to Dick Oakwood and cried, "Say it looks to me like a sandstorm over there. Maybe we had all better get under cover!"
Across the desert, far away, Dick saw a cloud of dust rising into the hot blue sky and called Raal.
"Is that a sandstorm?" he asked.
Raal studied the horizon carefully with narrowed eyes. "No, Master. When the sandstorm comes from the desert, it is not like that. Overhead the color changes and threatens danger. It may be a herd of wild horses that raises the dust."
"Do wild horses run about on the desert?" asked Dan.
"Never before have I seen them, but of late I have seen many strange things. I have seen birds that carry men and I have seen the sun darkened."
Dick took his binoculars and studied the morning cloud, but it was too far for him to make out what was kicking up the dust. Dan looked without success, and Dick turned to the natives.
"You try what you can see," he said to Raal, handing over the binoculars.
