At Liegan, California, the directionagain changes to south, for about 25 miles, to Scott, where there is anotherabrupt change in the general direction to slightly north of west for a dis-tance of about 100 miles, to Merlin, California. Here the general directionagain changes to due south, as far as Stockton, a distance of approximately150 miles, where there is another turn to the west until the road reachesOakland. From Marysville to a point about two miles west of the SanJoaquin river, a distance of 102 miles, the road is practically level, whenthere is another ascent of 1 per cent westward to Altamont tunnel. Thesummit, 750 feet above sea level, is a little west of this tunnel, and fromthere the grade descends at .8 per cent, with a few breaks, to Xiles, fromwhich point westward the grades are undulating and varying from .4 to1 per cent, to Oakland.
