Text continues: Help Uncle Sam to win the war by following these directions: 1. Fire small amounts of coal often. 2. Keep fuel bed even by putting coal on thin spots. Avoid raking and slicing. 3. Keep fuel bed about six inches thick. 4. Look out for air leaks in brickwork. 5. Increase or decrease steam pressure by opening or closing draft damper in uptake. 6. Clean fires well when the demand for steam is small, and while cleaning have the draft damper partly closed.
