Description: Original caption: "The upper works of the Relay Mine No. 3, Centerville, IA. The house in the foreground contains the hoisting engines. The shaft is in the center. The drum-like structure on the right is the fan which ventilates the mine. The trestle running to the left is for carrying away the refuse. The end of the dump pile shows just beyond the trestle. The weighing and storage sheds are beyond the shaft."
