Gentlemen the United States needs your help! : Be a fighting member of the fireman's army! You are boss of the coal pile and your fight is to save the coal to help the boys "over there." Your work is part of the war work of the country. Everything you save, especially coal, can be used somewhere else, to save and protect lives and preserve liberty. : How you can help : inspect, adjust, and oil carefully. Properly adjusted and smooth running cars save power. Turn off compressors and lights in idle cars. Do not burn lights or run shop and other motors except when necessary. Power used here is utterly thrown away. Keep brakeshoes clear of wheels. there is no worse power thief on the railroad than a dragging brakeshoe. Reduce car shifting to the absolutely necessary movements only. Reduce coal used for heating by keeping shop and car doors shut
