There are generally iron flat sheets at the stations over which the tubs are brought fromthe opposite side of the way. A tub, after having been passed over the flat sheets, is allowed tobe altogether moving on the rails again before it is touched by the chain, in order that the chainmay be sure to reach it in the centre. The method of leading coals by the endless chain as adopted at Clifton Hall Colliery, whichconsists in moving the tubs by the weight of the chain alone, there being no forks on the tubs, can HAULAGE. 1877 only be recommended when the plane to be worked is level or nearly level, and where the systemis not extensively applied.
