He held out both hands at once; and, as it happened, he caught hold of one each of Gerald and Jack, and they returned his greeting as heartily as it was given. Then he caught sight of Monck, who was standing a little in the background. At once he made a dart for him.

'Why, there is Monck Affelda!' he cried. 'You have returned, then! Welcome, dear friend! I was afraid that, perhaps, when you got back to your own world you would stay there, and we should never see you more!'

'Alondra, here are others waiting to know you!' the king reminded him.

And the lad at once turned obediently, with a look of quick apology at Monck for not saying more at the moment.

All the rest of the strangers having been duly presented, Ivanta gave his attention to his own subjects, who were now streaming up the ladders which had been let down the sides of the aerostat and crowding the deck to pay their respects to their sovereign.

Alondra, meantime, stepped back to where the two chums were standing with their guardian and the engineer, and commenced a lively chat, asking them a hundred questions concerning the world they came from, the incidents of the voyage, and so forth.

Both Gerald and Jack took to him at once. It was almost impossible, indeed, to do otherwise. His frank, gay, smiling manner, his attractive face, and easy, graceful air captivated them completely. Never, they afterwards declared, had they met so attractive a personality. 'A true son of the stars,' Jack dubbed him. Glad were they then that they had made such good use of their time and had learned the language of their hosts in advance. Even Silas, who presently joined the group, became quite amiable under the young prince's genial influence; and little Freddy fell in love with him then and there.

Naturally, amongst these young people, there was a lot to ask about on both sides. Question followed question, inquiries and explanations were interrupted with exclamations of surprise, wonder, admiration, and delight.

Then Alondra caught sight of others who were known to him, among them Aveena the young noble, and went off to greet them on their return.

'He is a splendid youngster, the prince,' observed Monck admiringly. 'Everybody loves him. Clever, too—quite a young inventor, I can assure you.'
