Grasping his companion by the arm, he crept to the right, finally emerging from behind a rise of ground which had shielded their progress.

"Look there," he whispered.

Tad looked. Below him lay a broad, open mesa, its upper end within a stone's throw of where he stood. But that was not what attracted his attention. A band of horses of many colors and sizes stood arrayed on each side of the little plain.

Advanced a few yards from the band on the right, was a magnificent black stallion, pawing the earth and uttering shrill challenges. On the other side of the field was the Angel. He was not pawing the earth. Instead he was standing proudly, his curving neck beautifully arched, his pink nostrils distended and held high.

"What a wonderful animal!" said Tad under his breath. "And that black! I can understand why he is called Satan. What are they going to do?"

"Fight! Don't you understand? They're getting ready to settle their old score, and a merry mix-up it'll be," replied the cowboy in a whisper.

"Yes, yes," breathed Tad, scarcely able to curb his excitement.

"There they go!"

With a wild scream Satan and the Angel bounded into the center of the field. As they neared it each swerved to his right and dashed by, avoiding his opponent.

"Act as if they were afraid of each other," said Tad.
