In running fly level from a BM of R. L. 350.00 m, the following readings were obtained: Back sights: 1.315, 2.035, 1.950, 2.535 Fore sights: 1.155, 3.400, 2.255 From the last position of the instrument, 5 pegs at 20 m interval are to be set out at a uniform rising gradient of 1: 40. The first peg is to have an R. L. of 347.240 m. Workout the staff readings required for setting out the top of pegs on the given gradient by height of collimation method.

(b) In running fly level from a BM of R. L. 350.00 m, the following readings were obtained:
Back sights: 1.315, 2.035, 1.950, 2.535
Fore sights: 1.155, 3.400, 2.255
From the last position of the instrument, 5 pegs at 20 m interval are to be set out at a uniform rising
gradient of 1: 40. The first peg is to have an R. L. of 347.240 m. Workout the staff readings
required for setting out the top of pegs on the given gradient by height of collimation method.
