After this bloody sea fight, which lasted only fifteen minutes, but in which nearly two hundred and fifty men were killed and wounded, the "Shannon" sailed away for Halifax, taking with her the "Chesapeake," with the dead body of its brave commander on board. When the two vessels entered the harbor, Lawrence lay upon the quarter-deck, wrapped in the great flag of the "Chesapeake," while all the men on the British vessels in the harbor manned their yards, and shouted a wild welcome to the victorious "Shannon." But the flag which floated from the masthead of the British frigate held no more honorable position than that which covered the dead body of the American hero. THE STORY OF THE TELEGRAPH AND THE STEAMBOAT. It will always be a source of commendable pride to the people of New Jersey, that their State was never backward in the political, social, or mechanical progress of this country. In fact, several of the most important steps in great movements for popular good have been made upon the soil of the State. Among the claims to preeminence which New Jersey can make in this respect is the claim that the first telegraphic message that was ever transmitted through a wire was sent at the Iron Works at Speedwell, near Morristown, at which place Professor Morse and Mr. Vail, son of the proprietor of the works, were making experiments with the telegraph. The first public message was sent more than six years later from Washington to Baltimore; but the message at Speedwell stands first, in the point of priority, of all the dispatches by magnetic telegraph which the world has known. When Professor Morse conceived the idea of communicating between distant points by means of electricity, he was not able to carry out experiments for himself, and having made the acquaintance of Alfred Vail, son of the proprietor of the Iron Works at Speedwell, he gave up his business as a portrait painter and went to Speedwell, where he and Mr. Vail worked hard in experimenting with the new invention. At last, when they thought they had brought it to such a point that they could make practical use of it, they determined to try to send a message through three miles of wire. If that could be done, they believed they could send one to any distance desirable. Currents of electricity had been sent through long lengths of wire by Mr. Morse in previous experiments, but in these cases nothing more was attempted than signals; no words or message had been sent, and the proposed experiment, therefore, was of great importance. Its success or failure meant success or failure to the magnetic telegraph.
