A stoker works four hours at a stretch, and during that time the temperature of his surroundings varies from 120 degrees to 160 degrees Fahrenheit. One stoker usually has four furnaces to attend to, and while feeding one furnace a man has to be extremely careful or his arm may be burned by the furnace behind him.
As a rule a man is occupied about three minutes at each furnace, and directly he has finished he rushes to the air pipe and waits until his turn comes again. The intense heat of the furnaces has sometimes rendered stokers temporarily insane, and there are many cases on record where they have jumped overboard after having made their way to the deck.
