"I should say, Leftenant, we could just do it."

At daybreak the wretched animals resumed their hideous struggle. There was a plateau for them to climb at the start, and by the time this labor was accomplished they were staggering with weakness, so that a halt had to be ordered on the windy brink of the acclivity. Thurstane, according to his custom, scanned the landscape with his field-glass, and jotted down topographical notes in his journal. Suddenly he beckoned to Coronado, quietly put the glass in his hands, nodded toward the desert which lay to the rear, and whispered, "Look."

Coronado looked, turned slightly more yellow than his wont, and murmured "Apaches!"

"How far off are they?"

"About ten miles," judged Coronado, still gazing intently.

"So I should say. How do you know they are Apaches?"

"Who else would follow us?" asked the Mexican, remembering the son of Manga Colorada.

"It is another race for life," calmly pronounced Thurstane, facing about toward the caravan and making a signal to mount.
