'Coal at all White Oak shafts mines is handled on self dumping cages, which handle the coal uniformly and with a minimum of breakage. Note how evenly the coal is flowing from the mine car. Much more rapid of course than the picture indicates, but it shows how well designed the equipment must be to handle the coal in such splendid manner.'
'Loading [sic] from heading to face conveying on 9% grade to boom, coal wet; distance to face 174 feet; flight type boom; Note: up until the time of taking pictures A-1-A-2-3&4 no jacks were set to support conveyor or drive.'
