When the tim-ber skip reaches the level, the cageman rings I bell andthe hoistman stops the cage and returns the signal, where-upon the ski]> can be unloaded. This seems a longprocess, but in lad is \en satisfactory after it has beenm use for a short time. In the described movemenl ofcage and skip, 56 hells had to be rung, hut thetion is not as long as it sounds. The skips run in counterbalance. The skip Irings 6 or 7 bells, depending on whether he is going tohoist ore or rock. The hoistman returns this -and the lander al the surface fixes the proper dump andreturns the signal. The ski], tender then rings I bellto hoist, and the hoistman returns the signal and hoiststhe skip.
