Evidence of American enterprise was everywhere to be seen. On the banks of the Merrimack River in Lowell, Massachusetts, Nathan Appleton was successful in the manufacture and printing of American textiles; in Cincinnati, Nicholas Longworth's horticultural experiments made strawberries cheap and plentiful; in Boston, Elias Howe invented a "new and useful machine for sewing seams," for which he was awarded a patent on September 10; from New York, Commodore Cornelius Vanderbilt sent his steamships afloat to a hefty profit; and in all directions, the lines of Samuel F. B. Morse's magnetic telegraph pushed forward. "All physical and scientific difficulties are vanquished," Morse wrote in October.
