The intermediate stakes C, D, E and so on are developed by observation the same team reading. This technique appropriates for comparatively uniform inclines. The index of the vernier of the Abney's degree is readied to the reading corresponding to offered quality. The instrument is after that held over the beginning point at a recognized elevation, claim, 1.

One more post, on which the vane is repaired at same height, is held over the following point at some range apart state 30 to 40 m. The pole is then elevated or lowered up or down hillside until the vane is bisected and also the bubble centered.
