" Because of this genuine love for horses, the beautiful wild-horse panorama beneath Pan swelled his heart. He gazed and gazed. From near to far the bands dotted the green-gray valley. Far away this valley floor shaded into blue. Near at hand the colors were easily distinguishable. Blacks and bays, whites and chestnuts, pintos that resembled zebras dotted this wild pasture land. The closest band to where Pan and Blinky stood could not have been more than a mile distant, in a straight line. A shiny black stallion was the leader of this herd. He was acting strangely, too, trotting forward and halting, tossing his head and long black mane. "
