The act outlawing the slave trade in 1808 furnished another source of demand for fast vessels, and for another half century ships continued to be fitted out and financed in this trade by many a respectable citizen in the majority of American ports. Newspapers of the fifties contain occasional references to the number of ships sailing from the various cities in this traffic. One account stated that as late as 1859 there were seven slavers regularly fitted out in New York, and many more in all the larger ports.
