We rested for an hour or more at the half-way house, and then resumed our journey: the morning story over again,--upward and downward and roundabout, with woods and hills everywhere, and two mountains still to put behind us. We should be in Highlands before dark, the driver said; but one contingency had been left out of his calculation. When we had been under way an hour, or some such matter, he began to worry about one of the horses. My own eyes had been occupied elsewhere, but now it was plain enough, my attention having been called to it, that “Doc” was leaving his mate to do the work. And Doc was never known to play the shirk, the driver said, with a jealousy for his favorite’s reputation pleasant to see and honorable to both parties. The poor fellow must be sick. “Didn’t he eat his dinner?” I asked. “Yes; there was no sign of anything wrong at that time.” Then it could be no very killing matter, I said to myself; a touch of laziness, probably; who could blame him?--and I continued to enjoy the sights and sounds of the forest. But my seatmate, better experienced and more charitable, was not to be misled. Little by little his anxiety increased, till he could do nothing but talk about it (so it happened that we crossed the North Carolina line, and I was none the wiser); and before long it became evident, even to me, that whatever ailed the horse, sickness, laziness, discouragement, or exhaustion, he must be carefully humored, or we should find ourselves stranded for the night on a lonesome mountain road. Slower and slower we went,--both men on foot, of course, up all the ascents,--and worse and worse grew Doc’s behavior. I was sorry for him, and sorrier still for the driver, who was thinking not only of his horse and his passenger, but of himself and his own standing with the owner of the team. He was sure it was none of his fault, he kept protesting; nothing of the kind had ever happened to him before. Finally, seeing him so miserably depressed (for the time being every misfortune is as bad as it looks), so quite at the end of his wit, and almost at the end of his courage, I said, “Why not take advice at the next house we come to? Two heads are better than one.” That was a word in season. To take advice would be a kind of division of responsibility. It is what doctors do when the patient is dying on their hands. The man brightened at once.
