Contained within the 2nd Edition (1915) of the Atlas of Canada is a map that shows the telegraph network for Maritime Provinces and areas of Quebec. More then one line may have followed the same route, but only one line is indicated on the map, especially in larger cities. Therefore, well-settled portions of the country are likely to have more then one telegraph line serving the principal towns along each route indicated. Most telegraph lines run alongside railways. The map includes the routes and destinations of underwater cables. The railway systems and telegraph network cross the Canadian-United States border. A table indicates the range (in miles) of 25 important wireless stations.
