THE term 'automatic' usually implies some complicated, intricate device that does the work of attendants or operators. At the Tennessee Copper Company's mills a simple combination of two common, ordinary pieces of standard equipment controls the grinding and classification without the presence of operators.

To shut down the plant at the week end, the motor switches are pulled and the water valves closed.
