6. If your Ball lye in a made Hazard, or in any of the Water-tracts, for draining the Links, where the cut of the spade appears at the place where the Ball lyes, it may be taken out, dropped behind the Hazard, and played with an iron club without losing a stroke; or in the option of the Player, the Ball to be tee'd, and lose one. And in no case, but what is mentioned in this and the immediately preceding law, can a Ball be lifted, but must be played where it lyes.
