When Bright-Wits had made obeisance, Garrofat arose and ordered a slave to remove the rug which lay upon the floor before the throne. This done, there was revealed a square, slightly sunk into the marble, at one corner of which could be seen the head of a silver serpent set in the stone; while at the opposite corner the tail of the serpent was visible. But for these two pieces the square was blank. Doola now entered, followed by a slave who bore a number of pieces of metal which proved to be the missing parts of the serpent's body. These were placed beside the square.
