Group portrait of miners and horses inside a mine. 'Dr. Parkinson said a copy of this picture appeared in Natural Geographic's Pictorical Study of Appalachia.'
'Shuttle Cars: Here are pictured loaded and empty shuttle cars sometimes called buggies. Note the noveyor on the bottom of the empty car for unloading the coal at a central loading station, into the mine cars. This equipment is propelled by huge batteries or electric cable and of course requires no track. Track-mounted mechanical loaders load directly into the mine car.'
