Excerpt from Johnson's Tables: Stadia and Earth-Work Tables, Four-Place Logarithms, Logarithmic Traverse, Table, Natural Functions, Map, Projections, Etc

Table IV gives logarithmic sines and cosines to four places for computing latitudes and departures when the angles are read from zero to 360 degrees. It can of course be used for bearings reading from zero to 90 degrees, as is ordinarily done in compass work. In stadia work, and always in transit work where the instrument is graduated continuously to 360 degrees, this table will be found very convenient for coordinating trav erse lines, as well as for computing latitudes and departures for closed surveys.
