| Jacob's staff | A single staff or pole used for mounting a surveyor's compass or other instrument. Sometimes used in place of a tripod. | HDBK-850 |
| Jaderin wires (base apparatus) | An apparatus used for base line measurement. It consists of separate steel and brass wires, extended under constant tension over reference tripods in the line of the base. The coefficients of expansion and lengths at a certain temperature of the two wires having been found, the temperatures of the wires themselves may be deduced from the difference of the measurement of the same distance by the two wires. With these temperatures known, the length of the base may be accurately obtained. | HDBK-850 |
