Clara Township Map ca.1885
- Media Type:
- Item Type:
- 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.
