146 INTRODUCTION. 



we may safely claim, that for suitableness to our social state, and for all that can 

 minister to domestic convenience and comfort, the edifices of our citizens are not 

 surpassed in any other community* Our naval architecture may perhaps justly 

 be re<yarded as a peculiar triumph of American genius. Our packet ships en- 

 gaged in foreign trade, and especially the steam palaces which float upon the 

 Hudson river. Long Island Sound and the lakes, combine the elements of strength 

 and beauty with great speed and perfection of internal arrangements. While 

 the civilized world is in the full enjoyment of the advantages of steam naviga- 

 tion, the people of New- York, at least, need not to be reminded of their obhga- 

 tions to her owa eminent citizens, Robert Fulton, John Stevens and Robert R. 

 Livingston. Experiments on steam navigation were commenced in 1791, by 

 John Stevens, of Hoboken. He invented the fiirst tubular boiler. His first 

 attempts were made with a rotary engine, for which, however, he speedily sub- 

 stituted one of Watts'. With various forms of vessels, and different modifica- 

 tions of propeUing apparatus, he impelled boats. In 1797, chancellor Livingston 

 built a steamboat on the Hudson, and the legislature granted an exclusive privi- 

 lege of steam navigation, on condition that he should, within a year, produce a 

 vessel impelled by steam at the rate of three miles per hour. Being unable to 

 perform this condition, the privilege failed. Livingston and Stevens united their 

 efforts with Nicholas Roosevelt in 1800, but without success. Chancellor Living- 

 ston pursued his favorite object in Paris, where he engaged the efforts of Fulton. 

 Fulton, after a trial of various other apparatus for propulsion, decided that the 

 paddle wheels possessed the greatest advantage. He then planned a mode of 

 attaching wheels to Watts' engine, and finding the experiment successful in a trial 

 on the Seine, it was determined by him and Livingston to build a large boat 

 upon the Hudson. He then proceeded to England, and personally superintended 

 the construction of a new engine by Watts and Bolton. This engine was re- 

 ceived in New- York in 1806, and the vessel prepared for it was set in motion in
