running at large upon the prairie ranges were seen approaching the settlements in anxious haste. As the long line of clouds slowly arose, the lower portion, which seemed to touch the earth, became of inky blackness. We could now faintly hear long continued rumble of thunder and for some time sharp tongues of lightning had been visible. The atmosphere, the haze and the rising bank of clouds had a weird unnatural appearance and the oppressiveness of the lifeless heat became almost unendurable. It was now noticed for the first time that the light-colored upper clouds, which resembled the dense smoke of a great prairie fire, were rapidly moving from the north and south toward the center of the storm cloud, and, as they met, were violently agitated like boiling water descending in a rapid movement to the black cloud below.
