"Now listen to me," said Alicia. You must let yourself down by your hands into the passage, which is about four feet high; stoop your head, and walk straight along it till you come to a sharp turn which will take you to the left, and at the extreme end of it you will find a short ladder below a trap-door like this, which you will have to unbolt; that door opens into the flooring of my lady's dressing-room, which is only covered with a square Persian carpet that you can easily manage to raise.
