The 200 ft.level will eventually be connected in the same way or separatepockets may be cut out below that level. The skip loading device is shown in Figure XVI. Thefinger gates shown in the drawing is supplemented by an extragate made out of a piece of sheet iron. By this means the fineswhich would naturally slip through the fingers of the main gateare caught and prevented from going down the shaft.
