'I do not see how that could possibly be,' returned Fumenta, with another shake of his head. 'I have never heard of him before, and he knows no more about me. But his future, if he lives, shall be my care. I can make him rich, wealthy—ay, I can make him one of the wealthiest men on our globe—and I will do so out of gratitude for what he did. For know, oh king, that I made but recently a great discovery! In one of the passages beneath the ancient volcano I came across a gold-mine—a veritable cave of gold! It was to that I referred when I said I could supply you with gold to carry on your warfare with Agrando. What you do not require I shall divide between this young man and those who have been my faithful followers.'

'You shall tell me more about it at another time,' rejoined Ivanta kindly. 'As to what I shall myself require, it will, all being well, be paid back later on; for I have no wish to make your friends' share less than it would otherwise have been. Send me word if you notice any change in the young man's condition,' he added, as he left to continue his round of inspection.

Meanwhile, the two chums and Alondra were constantly in and out asking for news of Malto. To them the unexpected success, thus far, of their expedition was cruelly saddened and overshadowed so long as his life was in danger.

'We owe him much,' Alondra declared. 'But for him we should now be Agrando's prisoners, to a certainty.'

'There is no doubt as to that,' Gerald agreed. 'But apart from any such consideration, I like him immensely on his own account. I wonder who he is? There is some mystery about him, I feel sure. Some sad event, I fancy, must have happened to him which has thrown a blight over his whole life.'

'For the matter of that, to be a sort of slave to Agrando is enough to blight anybody's life!' cried Jack warmly. 'Anyway, whoever he is, I feel sure he is well-born. His whole manner and bearing—ay, and his instincts, so to speak—tell you that much.'

Thus, in low and sorrowful tones, did they speak of their wounded friend while they waited about, anxious for bulletins. It was curious to see what a good impression the young fellow had made upon all those who had been his companions, even for so short a time.

But their talk was suddenly ended, and their thoughts turned into other channels, by news that was just then brought in that a large fleet of airships had been descried by their aerial scouts.

'Those who think they know,' Monck announced to Ivanta, 'declare that Agrando himself is probably with them. They recognised the Alsperro, which, as you know, sir, is the former warship which he has been using as a yacht. She is now, I suppose, to act the part of a war-vessel once more.'

Fumenta, on hearing the news, hurried from the couch of the wounded youth to confer with Ivanta.
