"Jee-rusalem! but it's a steep road," Jerry said presently. "I am dog-goned if I can guess how the red-skins ever discovered it. I expect they must have tracked some game up it, and followed to see where it went to."

The trail wound about in a wonderful way. Sometimes it went horizontally along narrow ledges, then there was a bit of steep climbing, where they had to lead their horses; then it wound back again, and sometimes even descended for a distance to avoid a projecting crag.

"Ah! would ye, yer varmint?" Jerry exclaimed, as a shot rang out from the valley below and a bullet flattened itself against a rock within a foot or two of his head. The shot was followed by a loud yell from below, as a crowd of mounted Indians rode at full gallop round the angle of the ravine.

"Hurry on, Hunting Dog, and get round the next corner, for we are regular targets here."

A few yards farther a turn of the path took them out of sight of the Indians, but not before a score of bullets came whistling up from below.
