Lining and marking
Chaining on uneven or sloping ground
Lining and marking
The follower holds the zero end of the chain at the terminal point while the leader proceeds forward with the other handle in one hand and a set of 10 arrows and a ranging rod in the other hand. When he is approximately one chain length away, the follower directs him to fix his pole in line with the previous pole. When the point is ranged, the leader makes a mark on the ground, holds the handle with both the hands and pulls the chain so that it becomes straight between the terminal point and the point fixed. The leader then puts an arrow at the end of the chain, and then the leader swings the chain slightly out of the line and proceeds further with the handle in one hand and the rest of the arrows and the ranging rod in the other hand. The follower also takes the handle in one hand and ranging rod in the other hand and follows the leader till the leader has approximately travelled one chain length. The follower puts the zero end of the chain at the first arrow fixed by the leader and ranges the leader who in turn stretches the chain straight in the line and fixes the second arrow in the ground and proceeds further.
