The northern proposal of Shaffner and the southern French proposal are also shown. The 1866 cable was laid by the SS Great Eastern. Existing cables are listed (left and right; total of 12,850 kilometres) and the cross-section of the 1858 cable is shown at top left and top right. Published by George Washington Bacon (1830-1921).
