It is, how- ever, more frequently done by means of the common plough in the following manner. In the figure below, let ABCDEF re- present the apices of the old drills; let the plough be supposed driven in the direction from H to I, that is just along the centre of the drill, until it arrives at the headland at I; let it then turn to the right, and entering at K, the centre of the next drill, pass along the centre of the drill in the direction KG.
