Dick explained to Raal, who was keen to learn the new sport, the principles of taming and riding unbroken horses and the Taharan chief was eager to begin.

With a deep bow he begged Dick to accept an Arab gun he had captured and declared that when his tribe had learned to ride the wild horses, they would all set out to find the Arabs and raid them in turn.

Suddenly they were interrupted. Queen Vanga came to them, weeping and tearing her hair.

"Cimbula is gone!" she cried. "Where is Cimbula?"

Dan laughed.

"Your boy-friend was taken by the Arabs," he said. "You'll never see him again."

"I hope not," said Dick.

"The Arabs will put him on the chain gang," chuckled Dan.

"Never!" cried the old queen when Dan's remark was explained to her. "Cimbula works strong magic. If he is taken by the Arabs, Cimbula will become their chief."

"There may be something in that," said Dan. "The witch-doctor is clever enough to get out of any kind of a scrape."
