From the foregoing we learn the reason for the secret invention he had in mind during the years he spent in France. Robert Fulton planned to build a boat to descend beneath the water, which should carry masses of gunpowder to be placed wherever desired. These bombs, as we would call them, could be set by time-clocks so that they would later discharge their fire. We are familiar enough with submarines, now that they are in use in our own and other navies, but how impossible such a contrivance seemed in Fulton’s day! He called his invention “torpedo,” a name which has since been universally used for all such submarine vessels. He had his inspiration for the name from a strange fish of which he had read in the travels of Sir Thomas Herbert, where it was described as a “Torpædo or Cramp Fish” which, when the explorer and his companion took in their hands, alarmed them so greatly that they trembled; for “it let forth a cold breath upon them, so they would be so frightened that they would let it go.” You will see that Fulton’s strange boat, like this fish, was to let forth a strange breath of fire upon its enemies. He chose the name well. This dreadful machine of war seemed indeed a curious instrument to bring peace. His plan was to manufacture so deadly a weapon of warfare that no nation would dare to enter into a battle on the seas. Fulton had to tarry three weeks at Calais before his passport arrived. With this he soon reached Paris. He found the city gay and happy, with all remembrance of warfare put away. He sought lodgings at an excellent hotel where he was fortunate in meeting an American gentleman, Joel Barlow by name, and his wife. Between the three there arose a lifelong friendship of rare intimacy. Fulton was always happy in the selection of friends, in this instance particularly, for Barlow was a man of considerable distinction in literature, statesmanship, and philosophy. Fulton was a young man of agreeable presence and attractive manner and Mr. and Mrs. Barlow became greatly interested in him. When they moved into their own house, having no son of their own, they invited Fulton to live with them, and the friendship so strengthened that for seven years Fulton remained, almost as a son, in their home. Mr. Barlow had been American Minister to Algiers, where he made important treaties and accomplished valuable diplomatic service in what was then a very difficult field. He was a man of wealth, and when released from office at the embassy, he moved to Paris where he could establish a home and live among his books and papers; for he was an industrious writer of political and historical essays.
