He pointed across the river, out upon the prairie; and following the direction of his finger, I saw not more than a mile or two away a single horseman proceeding leisurely from us.

“Who can that be?” I asked half to myself, still watching the receding figure.

“Why he’s the one that sent that bullet across the water after us, and I’m thinking it’s lucky for him, he’s going another way. If I should get my hands on him, he would remember the time.”

And Nat extended his arms energetically, and shook his head spitefully by way of emphasizing his remark.

I continued gazing after the unknown person. At first I supposed it was an Indian, but at that distance, and with his back toward us, it was almost impossible to judge accurately. A moment’s thought convinced me that it was a white man. I could make out the hunting-cap of the trapper, and was soon satisfied he belonged to that class. His horse was walking leisurely along, and he seemed totally unaware of the proximity of strangers.

But who could it be? Was it he who had fired the well-nigh fatal shot? And what meant his actions in thus willfully leaving us? These and similar questions I asked myself, without taking my eyes from him, or heeding the numerous questions and remarks my companion was uttering. But, of course, I could give no satisfactory solution, and when his figure had grown to be but a dim speck in the distance, I turned to Nat.

“We may see him again; but, if I don’t know him, I know one thing, I’m wonderfully hungry just now.”

We partook of a hearty breakfast, my appetite for which was considerably weakened by the occurrence just narrated. Without much difficulty we forded the Republican Fork, being compelled only to swim a few strokes in the channel, and reached the opposite side, with dry powder and food.

Here we made a careful search of the shore, and ascertained enough to settle beyond a doubt the identity of the horseman with the would-be assassin of the night before. His footprints could be seen, and the place where he had slept upon the ground, together with the scraps of meat. By examining the tracks of his horse, we discovered that both hind feet were shod; this decided our question of his being a white man; and although it cleared up one doubt, left us in a greater one. He could not have avoided the knowledge that we were of the same blood, and what demoniacal wish could lead him to seek the life of two harmless wanderers? Be he who he might, it was with no very Christian feelings toward him that we took the trail of his horse, and pursued it.
