The Bureau International des Administrations Télégraphiques or the International Telegraph Union was established in Paris in 1865 by twenty founding nations with a view to the regulation and co-ordination of international telegraphic communication. The union was a highly successful organization and continues to exist as the International Telecommunications Union with 120 members. The Union published this map with updated information on many occasions. This is the earliest copy of the map held by the LAC. Shown are the submarine and major land telegraph lines of the world. The Atlantic cables are dated. This copy is signed by F.N. Gisborne, Superintendent of Telegraphs and Signals for the Government of Canada.
For later copies of this map see: H3/10000/1887, 1888, 1893, 1900, 1906
