We found the railroad, however, to be of the roughest and most difficult character. The grades were very heavy and the curves numerous and sharp. We seemed to be running towards every point of the compass. The deep valleys and steep hills of this part of the country had rendered the building of the road difficult and costly. There were numerous high embankments where an accident would be of deadly character. The track was also uneven and in generally bad condition, for the war had rendered railroad iron scarce and high-priced, besides diverting all attention and resources into other channels. This unfavorable character of the road very greatly increased the difficulty experienced by an engineer unfamiliar with the route in making rapid time, or in avoiding the varied difficulties incident to our progress. But we trusted implicitly that the far-sighted plans of Andrews, the skill of our engineers, and our own willing efforts would overcome all hindrances. Our first run was short. There was a sudden checking of speed and a halt. When those of us who were in the box-car pushed open our door and asked the reason for stopping so soon, we were told that the fire was low and the steam exhausted. This was startling intelligence, and caused a moment of consternation. If our "General"--the name of the locomotive we had captured--failed us at the beginning of the race, we too well knew what the end would be. For hundreds of miles on every side of us were desperate and daring foes. A hundred times our number of horse and foot could be gathered against us in a few hours. The most timid bird pursued by hounds feels safe, for its wings can bear it above their jaws. But if those wings should be broken! This engine gave us wings; but if it should be disabled no valor of ours could beat back the hosts about us, no skill elude their rage. But we found a less threatening explanation of our premature halt. The schedule time of our train was very slow,--only about sixteen miles an hour,--and the fires had been allowed to run down because of the expected stop of twenty minutes for breakfast at Big Shanty,--a stop that we had reduced to less than two minutes. Then the valve being thrown wide open, the little steam in the boiler was soon exhausted. But this difficulty was of short duration. A rest of three minutes, with plenty of wood thrown into the furnace, wrought a change, and we again glided rapidly forward.
