Very much a composite illustration of an underground incline or haulage brow. The haulage system uses a windless or 'crab' to haul or lower the platform. The boy on the left is standing in a landing or tunnel and loading coal into the shallow truck on the incline. A variation of this method of using an incline with a truck of the type shown was used in the Welsh quarrying industry until the 1960s in Blaenau Ffestiniog. It was used for taking men into and out of the mine. The author was advised to 'grasp the man nearest to you otherwise you'll fall out of the truck'. Later many underground inclines worked on a counterweight system. KH.
