Sea Plow being lifted aboard the John Cabot
A sea plow designed by Bell Telephone Laboratories to bury the underwater telephone cable below the ocean floor is lifted from the sea by a crane aboard the John Cabot, a Canadian cable repair ship and icebreaker. The plow was used by the American Telephone and Telegraph Company's Long Lines department to bury the shore-end sections of two transatlantic cables off the coast of New Jersey, USA.
