Method of measuring distances on ground.
1. Mark the position of survey stations whose distance is to be measured using wooden peg. (say A and B)
2. now, ranging is done if distance is more than one chain length(say C) to locate intermediate point.
3. Unfold the chain by taking both handles in a hand and throw it along line AB.
4. Remove peg and fix arrow at starting station A. fix arrow in groove of handle tightly.
5. Now, give jerks to the chain to open connected ring and links.
Also, keep another arrow at far end of chain
6. Measure the distance using brass ring and brass Talley’s provided at each 1m and 5m resp.
7. To measure further distance, chain is pulled longitudinally and fixed the handle in groove.
8. Repeat the procedure till chain reaches at station B. Thus total horizontal distance will be equal to addition of distances measured of each parts.
