Methods of measuring the vertical movement of points below ground are briefly reviewed, whereafter the application of one particular method is closely examined. The use of a mercury manometer, where only one leg of the mercury column is visible, is shown to be viable in South African temperature conditions and an improved method of determining the level of a buried settlement measuring cell, using a mercury column as a switch, is descriptionbed.
