There ensued a good deal of talk between Agrando and the other two, the while that they turned the scintillating heaps over and over, but it was carried on for the most part in such low tones that the listeners heard but little of what was said. Now and then they heard exclamations, or caught scraps of sentences, but these did not convey much information.

At last the conspirators put the two heaps back into their respective receptacles, which they themselves then carried into another chamber. Presumably, they there locked them up in some vault, and went their way; and all once more became quiet.

'Now's our time!' said Jack. 'If you take my advice, Prince, we shall slip back the way we came, and get out—if we're lucky enough to meet no one—through the glass-house where we found you. I should keep what you have learned to yourself till you are safely back home, and then tell your royal father, who will know what to do better than you or I, or Mr Monck.'

'I think you are right,' said Alondra musingly, 'although'——

'I am sure Jack is right,' Gerald put in. 'Those men, now that the fire of covetousness has been lighted in their breasts, would stick at nothing. They would murder you, and me, and all your suite, as soon as look at us, rather than give up their booty, or rather than risk our telling King Ivanta. So we'd better be discreet and keep still tongues in our heads.'

They left their hiding-place and made their way down the rows of seats. When, however, they reached the floor, Alondra looked round and whispered, 'I should like very much to know what this place is used for. It must have been constructed for some distinct purpose, and whatever the purpose it was a secret one. I see many things about, the uses of which I confess I do not understand, and yet I cannot help guessing; but I hope I am not right in my guesses, for they make me shudder.'

'I think I know what is in your mind,' returned Jack gloomily. 'I fancy the same thoughts came into mine; but I deemed it better not to say anything about them at present.'

As he spoke they distinctly heard a door opened and the sound of voices. There was nothing for it but to regain their former place of concealment. They had hardly entered it and closed the door, when a number of people came bursting into the place, looking about them as though in search of some one.
