We had sweet slumber that night in the keen air of the mountain top, and were ready for the last day of mountain work. We were fourteen miles from Jacksboro, and were resolved to reach the little town before night. The road was unlike the long inclined plane cut in the side of Pine Mountain. We were in the midst of a mass of irregular stony hills, all of them part of the highlands between the summits of the two ranges. It was hard and rough work, but we were not obliged to double the teams again. The last ascent of the Cumberland Mountains toward Big Creek Gap was over bare rock much of the way, the sandstone strata lying horizontal, and the road being a gigantic staircase in which the steps were sometimes a foot each, but oftener more, with an occasional rise of fully four feet in the edge of the rocky outcrop. In the road the sharp edges of these stairs had been rounded off, partly by wear and a little by mechanical means, but they distinctly retained the stair-like character and looked absolutely impracticable. At the worst places the teamsters would halt and throw together stones or branches of trees to fill the angle in the rock, then mounting, a whoop and a crack of the whip was the signal for the team to dash at the obstacle. The horses' shoes would strike fire from the level rock of the long "treader" above, the wagon would be bounced up the step, when a little bit of level would bring them to another rise in the staircase. We zigzagged along as the road sought the easiest places among the rocks, and perseverance at last had its reward when we crowned the summit and looked down into the broad and beautiful valleys of the Clinch and the Holston, the lovely tributaries which form the Tennessee River.
