Lithograph after Robert Dudley from 'The Atlantic Telegraph', a book by W H Rusell with 26 illustrations by Dudley, published in 1866. This shows the route, from Ireland to Newfoundland, which the 'Great Eastern' took when attempting to lay the second telegraph cable acros the Atlantic. The map shows how much cable was laid before bad weather forced the ship to abandon the cable and return to shore. The following year the 'Great Eastern' succeeded in laying a permanent line, reducing transatlantic communication times from the length of a sea voyage to a few seconds.
