Lithograph after Robert Dudley from 'The Atlantic Telegraph', a book by W H Rusell with 26 illustrations by Dudley, published in 1866. This shows a buoy being launched on 8 August 1866, to mark the spot where the transatlantic telegraph cable had been grappled and mended. This was during the succesful third attempt to lay a permanent telegraph cable acros the Atlantic, following failed attempts in 1858 and 1865. The succes of the operation was responsible for reducing communication times from the length of a sea voyage to a few seconds.
