8.6 Log and Picket Holdfast (Figure 8:4)
As in Figure 8:4, drive in four pickets about 400-500mm apart. Drive in a second row of four pickets 1m behind the first row. Lay a log of sufficient size for the job at hand, behind the first row of pickets. Lash each pair of pickets together.
This method is of particular use in wet or soft earth since the log acts as a beam and bears evenly against the front row of pickets.
