Question: Two pegs A and B are driven in the ground at a distance of about 120 m. A dumpy level is set up at station Q exactly mid-way between pegs A and B. The staff readings on pegs A and B were found to be 3.513 m and 3.149 m. The instrument was then moved and set up at a point P beyond peg A, in line BA produced at a distance of 20 m from A. The staff readings on pegs A and B were 1.763 m and 0.847 m respectively. What is the true difference in elevation between the two points? With the level in the same position at P what rod readings on B should the line of sight is adjusted. Check these reading against the true difference in elevation previously determined.
