But Fulton stood ready to prove them. During the years 1799 and 1800 he was busy demonstrating the accomplishments of his novel craft. He launched it in July, 1800, and proceeded to make a series of experiments in the middle of the Seine where he could plunge twenty-five feet. He took two persons down with him and his tests were encouraging although the swift currents of the tide made him decide to remove the boat to Havre on the coast, where he could attempt feats in the open sea.
His queer-looking boat, six feet wide and twenty feet long, was towed on two barges to Havre, where four days later it arrived and Fulton proceeded to put her through all sorts of “paces.” The vessel responded to his every wish and he imagined that universal peace would result from the use of the new subduing agent, the torpedo.
Great ideas move slowly,—their very immensity hinders quick progress. Fulton was under heavy expense in the building and testing of his strange boat. Barlow, who remained in Paris, wrote frequent letters of encouragement and forwarded drafts of money, profits which were Fulton’s share in the earnings of the panorama. Repeated entreaties to the Directory finally gained attention, and Napoleon showed enough interest to appoint a committee to examine the queer-looking vessel.
To this committee Fulton eagerly explained his invention. He tells the story in simple language and it is so thrilling that a copy will prove interesting. He writes:
Not having had time to busy myself with the drawings and description of the latest changes I have thought fit to make in my Nautilus, I take the liberty to recommend the model of it to your examination as the best means of enabling you to judge of its form and combinations.
Although having exact details of experiments, I shall limit myself to rendering here a succinct account of the most important of them:
First Experiment:—The Nautilus is 20 feet long and 5 in diameter and according to the calculations of Citizen Guyton it will contain a quantity of air sufficient for 3 men and a candle for three hours.
Second Experiment:—On 24th of August, 1800, I plunged in the basin at Havre to the depth of 15 feet having with me two people and a lighted candle; we remained below the surface for the space of one hour without experiencing the slightest inconvenience.
