(r) - under the cables, into the wind


After William Cooke and Charles Wheatstone had introduced their working telegraph in 1839, the idea of a submarine line across the Atlantic Ocean began to be thought of as a possible triumph of the future. Samuel Morse proclaimed his faith in it as early as 1840, and in 1842, he submerged a wire, insulated with tarred hemp and India rubber , [4] [5] in the water of New York Harbor , and telegraphed through it. The following autumn, Wheatstone performed a similar experiment in Swansea Bay . A good insulator to cover the wire and prevent the electric current from leaking into the water was necessary for the success of a long submarine line. India rubber had been tried by Moritz von Jacobi , the Prussian electrical engineer , as far back as the early 19th century.
