Among the legends which the traveler frequently hears, while crossing the prairies of the Far West, I remember one which accounts in a most romantic manner for the origin of thunder. A summer storm was sweeping over the land, and I had sought a temporary shelter in the lodge of a Sioux or Dacotah Indian on the banks of the St. Peter’s River. Vividly flashed the lightning, and an occasional peal of thunder echoed through the firmament. While the storm continued my host and his family paid but little attention to my comfort, for they were all evidently stricken with terror. I endeavored to quell their fears, and for that purpose asked them a variety of questions respecting their people, but they only replied by repeating, in a dismal tone the name of the _Lone Buffalo_. My curiosity was of course excited, and it may readily be imagined that I did not resume my journey without obtaining an explanation of the mystic words; and from him who first uttered them in the Sioux lodge I subsequently obtained the following legend: There was a chief of the Sioux nation whose name was the Master Bear. He was famous as a prophet and hunter, and was a particular favorite with the Master of Life. In an evil hour he partook of the white man’s fire-water, and in a fighting broil unfortunately took the life of a brother chief. According to ancient custom blood was demanded for blood, and when next the Master Bear went forth to hunt, he was waylaid, shot through the heart with an arrow, and his body deposited in front of his widow’s lodge. Bitterly did the woman bewail her misfortune, now mutilating her body in the most heroic manner, and anon narrating to her only son, a mere infant, the prominent events of her husband’s life. Night came, and with her child lashed upon her back, the woman erected a scaffold on the margin of a neighboring stream, and with none to lend her a helping hand, enveloped the corpse in her more valuable robes, and fastened it upon the scaffold. She completed her task just as the day was breaking, when she returned to the lodge, and shutting herself therein, spent the three following days without tasting food. During her retirement the widow had a dream in which she was visited by the Master of Life. He endeavored to console her in her sorrow, and for the reason that he had loved her husband, promised to make her son a more famous warrior and medicine man than his father had been. And what was more remarkable, this prophecy was to be realized within the period of a few weeks. She told her story in the village, and was laughed at for her credulity.
