As King Ivanta spoke to his visitors the words 'Welcome to Mars!' there came a rustling sound, and a strange figure, shining and glistening in the sunlight, suddenly appeared on the deck beside him.

So rapidly had it arrived that the startled spectators scarcely saw more than the sheen from its resplendent body before it was amongst them, alighting with the grace and ease of a swallow close to the king, whom it addressed in joyous, laughing accents, 'Welcome, father! welcome home!'

Even King Ivanta was evidently taken by surprise, for at first he scarcely seemed to understand this arrival any more than the strangers from Earth did. The next moment, however, he had clasped the radiant vision in his arms in a close embrace. Then he drew back and regarded the youth—for such the figure was—critically. 'Why, Alondra, my son,' said he, 'what is this surprise?'

Alondra, as the visitors were soon to learn, was Ivanta's son, his only child. He was about the same age as Gerald, with an exceedingly handsome, open, merry-looking countenance, lithe and graceful in figure and in every movement. On this occasion he was clad in a most bizarre costume, which included two large wings, just now folded back behind the shoulders, and trailing on the floor of the deck.

It was impossible to guess what these wings could be made of. The surface was composed of thin, feathery flakes in constant motion, which glistened in the sunshine with iridescent brilliance, something between the sheen of silver and the sparkle of crystal. A tunic of the same marvellous material covered the body to the knees, below which were attachments like smaller wings, which now fitted closely round the ankles.

Evidently this wondrous outfit was as new and surprising to the king as it was to the strangers.

The youth seemed delighted at the impression he had created. He walked to and fro, opening and folding his wings, and turning this way and that to show them off to advantage.

'Almost all my own invention, father,' he laughed, as he moved about—'mine and Amaldo's! We were afraid we should not get it finished and in working order before your return. Indeed, I only took my trial-flight in it yesterday! Is it not a splendid creation'?'

He opened the wings and fluttered them in the sunlight. Ripples of light and dancing colours ran incessantly over the surface, producing effects so exquisitely varied and beautiful as to be absolutely indescribable.

'It is perfect, Alondra! Truly, as you say, a splendid creation!' said Ivanta admiringly.
