Dick's aim was true—the vapors and clouds had not disturbed it—and when the rifle flashed, the pony bounded into the and fell dead. But the agile Sioux leaped clear and darted away. Dick marked his brown body, and then was his opportunity to send a mortal bullet, but a feeling of which he was almost ashamed held his hand. His foe was running, and he was no longer hunted. The feeling lasted but a moment, and when it passed, the Sioux was out of range. A moment later and his misty foe had become a part of the solid darkness.

Dick stood upright once more. He had been the victor in a combat that still had for him all the elements of the ghostly. He had triumphed, but just in time. His nerves were relaxed and unstrung, and his hands were damp. He carefully reloaded all the empty chambers of his repeating rifle, and without looking at the falling horse, which he felt had suffered for the wickedness of another, strode away again over the plain, abandoning the rifle of the fallen Sioux as a useless burden.

It took Dick sometime after his fight with the phantom horseman to come back to real earth. Then he noticed that both the clouds and the dampness had increased, and presently something cold and wet settled upon his face. It was a flake of snow, and a troop came at its heels, gentle but insistent, chilling his hands and gradually whitening the earth, until it was a gleaming floor under a pall of darkness.

Dick was in dismay. Here was a foe that he could not fight with rifle balls. He knew that the heavy clouds would continue to pour forth snow, and the day, which he thought was not far away, would disclose as little as the night. The white pall would hide the mountains as well as the black pall had done, and he might be going farther and father from his valley.

He felt that he had been released from one danger and then another, only to encounter a third. It seemed to him, in his minute of despair, that Fate had resolved to defeat all his efforts, but, the minute over, he renewed his courage and trudged bravely on, he knew not whither. It was fortunate for him that he wore a pair of the heavy shoes saved from the wagon, and put on for just such a journey as this. The wet from the snow would have soon soaked though his moccasins, but, as his thick deerskin leggings fitted well over his shoes, he kept dry, and that was a comfort.

The snow came down without wind and fuss, but more heavily than ever, persistent, unceasing, and sure of victory. It was not particularly cold, and the walking kept up a warm and pleasant circulation in Dick's veins. But he knew that he must not stop. Whether he was going on in a straight line he had no way to determine. He had often heard that men, lost on the plains, soon begin to travel in a circle, and he watched awhile for his own tracks; but if they were there, they were covered up by snow too soon for him to see, and, after all, what did it matter?

He saw after a while a pallid yellowish light showing dimly through the snow, and he knew that it was the sunrise. But it illuminated nothing. The white gloom began to replace the black one. It was soon full day, but the snow was so thick that he could not see more than two or three hundred yards in any direction. He longed now for shelter, some kind of hollow, or perhaps a lone tree. The incessant fall of the snow upon his head and its incessant clogging under his feet were tiring him, but he only trod a plain, naked save for its blanket of snow.

Dick had been careful to keep his rifle dry, putting the barrel of it under his long deerskin coat. Once as he shifted it, he felt a lump over his chest, and for an instant or two did not know what caused it. Then he remember the history and geography of the United States. He laughed with grim humor.

"I am lost to history," he murmured, "and geography will not tell me where I am."

He crossed a swell—he knew them now more by feeling than by sight—and before beginning the slight assent of the next one he stopped to eat. He had been enough of a frontiersman, before starting upon such a trip, to store jerked buffalo in the skin knapsack that he had saved for himself. The jerked meat offered the largest possible amount of sustenance in the smallest possible space, and Dick ate eagerly. Then he felt a great renewal of courage and strength. He also drank of the snow water, that is, he dissolved the snow in his mouth, but he did not like it much.
