An employee of the East India Company made an effort to lay a cable across the river Hugli as early as 1838. His method was to coat the wire with pitch inclose it in split rattan, and then wrap the whole with tarred yarn. W

The cable was weighted with pieces of lead fastened on every hundred yards. A few incoherent signals were exchanged and the communication ceased. A Boulogne fisherman had caught the new cable in his trawl, and, raising it, had cut a section away. This he had borne to port as a great treasure, believing the copper to be gold in some new form of de
