To the stake designating the height of wall or grade line nail the batter boards leveled on the triangle stakes. From this corner level and sight to all other corners and mark the height of grade line, then nail the batter boards on the stakes at grade height around each corner and angle. Measure the length and width of intended structure on the batter boards and from these measurements draw a line on four sides (fig. 4), sight across to see that all lines are parallel; if they are not, relevel to all corners to find the one that is out of level and raise the same parallel with other lines. (fig. 4 1/2.)
