They argued as they had always argued, Helen for reason and common sense and restraint, Bo on the principle that if she must fight it was better to get in the first blow.

The morning on which this argument took place Dale was a long time in catching the horses. When he did come in he shook his head seriously.

“Some varmint's been chasin' the horses,” he said, as he reached for his saddle. “Did you hear them snortin' an' runnin' last night?”

Neither of the girls had been awakened.

“I missed one of the colts,” went on Dale, “an' I'm goin' to ride across the park.”

Dale's movements were quick and stern. It was significant that he chose his heavier rifle, and, mounting, with a sharp call to Pedro, he rode off without another word to the girls.

Bo watched him for a moment and then began to saddle the mustang.

“You won't follow him?” asked Helen, quickly.

“I sure will,” replied Bo. “He didn't forbid it.”

“But he certainly did not want us.”
