"TOWARD the close of a warm spring day on April, 1867, luminous spots appeared both on the north and on the south of the setting sun. I noticed them as I returned to our lodge, after watering Is-spai-u and picketing him upon a patch of new sprouting buffalo grass close in front of camp. “Sun dogs!” I said to myself. “Strange that
they should appear at this time; they belong to the cold days of winter.” My heart misgave me. I had lived so long and so intimately with the Blackfeet that I had come largely to share their beliefs. Sun dogs are a warning
of misfortune that would soon befall either the tribe or some member of it." So begins the exciting tale of The Trail of The Spanish horse.
