It struck the rancher that it would be well to let the Sioux know that he was still on guard. He caught glimpses here and there of the upper part of a repulsive face, with its long black hair and serpent-like eyes, on the alert to catch him unawares, and he fired at the nearest.

The aim was good, but there was no reason to believe that he had inflicted harm, though he must have come nigh it.

Strange it is that in the most trying moments, when it would seem that a trifling thought should be impossible on the part of a person, he sometimes gives way to a fancy that is of that nature. Recalling the story which he had read when a boy, and which is familiar to all our readers, the rancher now picked up his hat at his side and gently raised it to view, taking care to lower his own head beyond reach of harm.

Instantly a couple of rifles cracked from the other side of the stream, and he smiled grimly when he saw the marks of the bullets in the crown.

"They shoot well," he said, turning his face toward his wife and holding up the hat, "but they made a slight mistake that time."

If the Sioux supposed that the last shots were fatal, they were likely to repeat their attempt to cross. That would never do, and, more with a view of letting them know no harm had resulted, than in the hope of inflicting injury, the rancher took aim at what seemed to be the forehead of one of the warriors, a short distance up stream, and fired.

To his amazement, the wild screech left no doubt that the shot was fatal. The bullet had bored its way through the bronzed skull of the miscreant, and the force of assaulting Sioux was now reduced by one-third.
