Passage 1
My steamboat voyage to Albany and back has turned out rather more favorably than I had expected. The distance, from New York to Albany is 150 miles. I ran it up within 32 hours and down in 30. I had a light breeze blowing against me the whole way both going ing, and the voyage has been performed wholly by the power of the steam engine. I overtook many boats beating against the wind and parted with them as if they had been at anchor. The power of boats run by steam is now fully proved. The morning I left New York there were not, perhaps, thirty persons in the city who believed that the boat would ever move one mile per hour or be the least use.
