都是一些僵尸粉，白搭！

Are the zombie powder, no use!

地已经浸透，种什么东西都是白搭。

The ground is completely saturated: it would be pointless to plant anything.

十点之后我们到冰凉的水里沐浴。没有父亲的允许，叫仆人给我加一壶热水调匀调匀凉水，也是白搭的。

After ten o'clock came the bath in icy-cold water; it was no use asking the servants to temper it with even a jugful of hot water without my father's permission.
