Thechimney was con-structed on theground, and raisedon a strong cast-iron bedplate, with hinge, by two hand-whims and blocks. Figs. 3, 4, 5, and 6 showvarious stages of its erection. The surface arrangements were very simple, the full tubs,containing about 8 hundredweights of coal, being run on a gang-.

If it happened that there wereno empty wagons, the coal was run into stock by light tip-wagons,stones being picked out by native boys (Fig. 7). Fig. 8 shows anarrangement for loading the coal from the smaller shafts intorailway wagons. The No. 3 or Mariana seam is entered by an incline shaft,and, at a depth of 320 feet on the incline, is being laid out towork a thickness of 21 feet of coal in a series of steps, a system
