"You seem to understand!" the man cried, his tired eyes lighting. "You seem to know what I need!"

Five minutes later he was rushing through the early morning air up the gulch, the Captain bearing him along with that free, firm, faultless stride that had swept him over those mountains for so many long, unmolested years.
