Erect a corner stump first. If the ground has been levelled it is immaterial from which corner you start, but if the ground has a fall, select the highest corner. Set a post or stump in position so that it stands plumb without support and just touching the building lines. Set out one side row first, then a row at right angles. After this, set out as convenient, but check the level of the diagonal, as well as around the outside.
Levelling is done with a straight-edge and a spirit level. Level to the stump which is as far away as the straight-edge will allow, work thus along the row, and fill in the in-between stumps afterwards.
Tall posts or stumps which exceed 1000 mm have to be braced.
