Notes:
The Map came from Andre Boissonneault, a contractor. The map is hand written on an oil cloth, and covers a total area of 63922 (unit of measure unknown).


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.
