The French Atlantic Cable: Brest - Duxbury, 1869 |
|
France laid its first submarine cable in 1869, between Doléen, near Brest on the western tip of the French mainland, and the islands of Saint-Pierre et Miquelon, off Newfoundland, Canada, with an extension to Duxbury, Massachusetts. The cable was laid by the Great Eastern, with the Hawk (laid the European shore end), Robert Lowe (landed the St. Pierre shore end), Chiltern, Scanderia, and William Cory (laid and landed the Sydney and Duxbury extensions). The illustration shows the three weights of cable used. All had an identical core of 7 copper strands. On the left is the shore-end cable, heavily armoured to resist damage from rocks and ships' anchors. On the right is the intermediate cable, used to run from the shallows near shore out to deeper water. In the center is the deep-sea cable, the main length of the run, and having the lightest armouring. The diagrams are to scale; the deep-sea cable is about 1" diameter. Telcon, the Telegraph Construction and Maintenance Company, of London, manufactured the Brest to St. Pierre section of the cable, and subcontracted W.T. Henley to make the St. Pierre to Sydney length. For more information see the main page for the French Atlantic Cable. Illustration from Guillemin's
