The men now take hold of the bull-wheels and draw up the slack until the sinker-bar rises, the ' play ' of the jars allowing it to come up 13 in.
If now the vertical movement of the walking-beam be 24 in., when 'it starts on the up-stroke the sinker-bar rises 4 in., and the cross-heads come together with a smart blow, then the auger-stem is picked up and lifted 20 in.
