One day Augustus asked Newt to ride along with him, much to Newt’s surprise. In the morning they saw a grizzly, but the bear was far upwind and didn’t scent them. It was a beautiful day—no clouds in the sky. Augustus rode with his big rifle propped across the saddle—he was in the highest of spirits. They rode ahead of the herd some fifteen miles or more, and yet when they stopped to look back they could still see the cattle, tiny black dots in the middle of the plain, with the southern horizon still far behind them.
