To determine the positions for the pegs 20 feet is measured off for the 

 headlands. Should the fence lines not describe a right angle, it may 

 be found as previously described. When this is done the square may 

 be completed, and the diagonal line found with the planting wire, and 

 the row of pegs placed in position. The pegging out of the whole area 

 may be completed by placing lines of pegs at right angles, or parallel 

 to the diagonal line as depicted in the illustration. 



In order to understand why the method of planting under review 

 is advocated when local conditions require it, and for the reasons 

 already explained, assume that a ridge runs in the direction of the

diagonal line, and that the land slopes abruptly from the ridge on 

 both sides. It will be seen that the trees run in rows parallel to the 

 ridge. This facilitates ploughing, spraying, &c., in that direction. 

 And suppose the dam (D) to be on the highest point of the ridge. 

 The water escapes at the vent (a) and is carried in the small drains 

 (B) and (C) down the headlands. The small arrows denote the 

 points at which the water may be diverted from the drains and 

 directed amongst the rows of trees. 



Tiow assume that the ridge runs in the direction to which the arrow 

 (A) points and that the dam is on the highest point in line with it. 

 Then it will be observed that, under these conditions, the square method
