Latitude and longitude stone

In the mid to late 1800s, experiments were carried out in which telegraph cables became part of the scientific methods used to determine longitude. International cooperation is required with observers at different locations to record the star transit in the sky, followed by intricate calculations to reach a conclusion. The Commercial Cable Company established this stone in the 1890s to mark the participation of the Waterville station in 1892 in the international project with the Greenwich Observatory and McGill University. Thus, the longitude of Montreal was determined.
