　　Decision 18-1/9 Ball Lodged in Tree Knocked Down by Outside Agency
　　Q: A players ball is lodged in a tree about eight feet off the ground. A spectator knocks the ball down from the tree. In complying with Rule 18-1, it is impossible to replace the ball in the prescribed manner in the tree because the spot where it lay in the tree is unknown or unreachable. What is the ruling?

　　A: Rules 20-3c and -3d cover cases in which the spot where a ball is to be placed or replaced is not determinable or a ball fails to come to rest on the spot on which it is placed. However, these Rules do not contemplate a case such as this one. Thus, in equity (Rule 1-4), if the position of the ball in the tree was such that the player could have made a stroke at it, the ball must be placed in the tree as near as possible to the spot from which it was moved, without penalty. Otherwise, the player must proceed under the unplayable ball Rule.

　　判定 18-1/9 停在树里的球被局外者击打下来

　　问：一名球员的停在了一棵树上，距地面大约8英尺。一名观众把球从树上击打下来。按照规则18-1的要求，不可能把球放回树上的原处，因为不知道原来球在树上的确切地点或者够不到。这时适用什么规则？

　　答：规则20-3c和-3d适合的例子是球被放置或重新放置的地点不能确定，或者一个球不能在放置的地点停住。不过，这些规则没有考虑到上述的情况。因此，本着公正的原则（规则1-4），如果球在树上的位置，球员能打一杆，那球必须被放置在最接近被移动时的位置，而且不受处罚。否则，球员必须按照不可打的球的规则来处理。
