- The subdivision of the township of Clara as subdivided into lots and concessions by J.W. Fitzgerald P.L.S., and shown on plan of survey, dated the 19th Nov 1885.
Early surveyors, like William E. Logan, used Rochon micrometer telescopes and targets (disk on a calibrated pole) to measure distance. Each microscope had a different calibration and therefore a different range. The instruments were calibrated against a distance measured with a surveyors chain (also known as Gunter’s chain). One chain had 100 links and was 66 feet (about 20 meters) or 22 yards long.
