In the Newspapers: Announcement that Mr. Fulton’s steamboat would begin its trip up the Hudson.
“Mr. Fulton’s ingenious Steam Boat, invented with a view to the navigation of the Mississippi from New-Orleans upwards, sails to-day from the North River, near the State Prison, to Albany. The velosity [sic] of the Steam Boat is calculated at four miles a hour; it is said that it will make a progress of two against the current of the Mississippi; and if so it will certainly be a very valuable acquisition to the commerce of the Western States.”
