Samuel Gompers' Own Account of the Fight for the 8-Hour Day. My earliest impression of the meaning of the eight-hour day came to me in my first home in New York City.

In 1870, he improved the devices to travel up to approximately 1,000 yd (910 m) at a speed of up to 6 kn (11 km/h), and by 1881 the factory was exporting torpedoes to ten other countries. The torpedo was powered by compressed air and had an explosive charge of gun-cotton.
