And so it came to pass that when, in due time, the wondrous aerostat Ivenia set out upon her return to Earth, she brought back with her a larger load of treasure even than she had carried to Mars. What had belonged to the Diamond King, Ivanta, with royal scrupulousness, restored to him. The rest of the jewels he presented to Armeath and his two wards, who in turn made over a share to their faithful servitors, all thus becoming rich beyond their wildest dreams.

At the last moment, before leaving Mars, the chums experienced a great disappointment. They had quite expected that Prince Alondra would accompany them; but King Ivanta firmly refused his permission. For the present, at any rate, he said, his son must remain to represent him, and to take his place in looking after his people. At some future time, perhaps, things might be different.

'That means,' Alondra whispered to Gerald and Jack, 'that he has it in his mind to bring me to see you later on. He is thinking of going upon a voyage of discovery to another planet, and I think I may be able to induce him to call for you to go with us.'

'Then,' said Gerald, 'it is not "Good-bye," but "Au revoir;" which, being freely interpreted, means "Perhaps Jack and I will see you again before very long!"'

And perhaps they will. Who can say? The two chums, at least, firmly believe that it will come to pass; and that they are destined to take their part in yet other journeys through space in the company of the genial King Ivanta and his vivacious son Alondra.

THE END.
