1. A Ton an Hour - USS Cairo Marker
Inscription. Look down to your left to see one of Cairo's restored firebox doors. Coal shoveled into the fireboxes heated the boilers. Steam from the boilers powered Cairo's engines and drove the paddle wheel. A gunboat without steam could not move and was helpless if attacked. Ironclads kept fires burning and steam pressure built up even when anchored. For hours on end, coal heavers piled coal from storage bunkers into the fire room, and firemen fed the fuel into each boiler's firebox.

[Caption]- Cairo's boilers burned a ton of coal an hour when the boat was underway.
