After a weary march we reached the edge of the desert plain, and found a small stream, clear but shallow; its banks lined with tall cottonwood trees. Here we rested, and our tired animals fully appreciated the cool water and the luxuriant "gramma" grass which abounded. While standing watch, a precaution we never neglected, I fancied I heard a distant rifle shot, and roused my father and brother, fearing Indians might be near at hand, for we were now in very dangerous country and father declared that he had seen "Injun sign" the day previous, but a scout through the cottonwood grove revealed nothing, and as the sound was very faint and was not repeated, we concluded it was only fancy; father muttering as he crawled under his blanket that I was getting too almighty scarey for a backwoodsman. This incident however aroused those apprehensive feelings that had before troubled me, but which had been quieted for a time by the uneventful nature of our journey. We were not again disturbed that night, but at sunrise we made a discovery that filled us with dismay--_We had lost the trail!_ This we were convinced was the result of our night journey, and father was confident that we could recover it; but, when after several hours spent in a fruitless endeavor to find where it crossed the stream, I urged that we should take our own trail back to the point at which it diverged from that of the train, he positively refused to do so; declaring that he wasn't a greenhorn to get scared at so small a matter, and that he should push on in a southwesterly direction, and take his chance of intersecting the trail, he asserting that we must have strayed to northward of it. My brother and myself protested against so rash an undertaking, but in vain; and we finally started on what was destined to be our last day's journey together. Our route now lay across a verdant and apparently boundless prairie. Far as the eye could reach it was a level plain, without landmarks, trackless as the sea, covered with a living carpet of emerald green. At another time I could have spent hours in gazing upon its vast expanse, and fancying its changed appearance when its surface should be furrowed by the plow and its fruitful soil reward the farmer's labor; but the presentiment of evil which I found it impossible to shake off, oppressed my spirits rendering me anxious and fearful. A few moments took us out of sight of the cottonwood grove, and but for the aid of father's pocket compass we could have had little idea of our direction, but by its assistance we traveled steadily in a southwesterly coarse, father being confident that we had strayed north of the trail and that by taking this course we must sooner or later regain it. Until nearly noon we kept steadily on, seeing nothing to indicate that we were near the trail. Just before noon we halted to rest and feed the animals and prepare a meal for ourselves.
