Incidentally the axemen straighten the trail more or less. The practice among the Indians, and after them the fur-traders and white trappers, was to follow an old trail until a fallen tree blocked the way. It would have to be a formidable obstacle to stop the average cayuse, but occasionally even that professional acrobat was brought to a standstill. The rider in such case never cut his way through if it could be avoided. He followed the lines of least resistance, turned right or left through the standing timber until he had won around the fallen tree and back to the trail again. The next man took the new path, until he was perhaps brought up by a later windfall and in his turn added another twist to the devious course of the original trail. It can readily be imagined that these forest thoroughfares did not at any period of their history represent the shortest route between any two points; and it may as well be admitted here that the policy of every man for himself in trail-making is as active to-day as it was a hundred years ago. Each one of us who has camped in unfamiliar valleys of the mountains must plead guilty to the same selfish practice. Hurrying along the trail, anxious perhaps to reach a certain camping-ground before dark, the temptation to flank a fallen tree rather than laboriously cut through it, is irresistible. The thought is there, though we may not admit it, that we may never come this way again, and the next man must look out for himself. It remains for the trail-makers to unravel the tangled skein and reduce it to something very remotely resembling a straight line. Having cut through the fallen timber and roughly bridged the deeper creeks, the result is a good pack trail. This is widened and cleared from year to year; levelled, graded and provided with substantial bridges, to convert it into a carriage road; and finally macadamized. And as the picturesque trail is converted into the eminently modern and respectable macadamized road, the equally picturesque pack-train disappears and in its place we see, and smell, that emblem of the twentieth century, the automobile.
