’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. ’The fleet which is approaching is far stronger than yours,’ Ivanta explained to him. ’You cannot hide your vessels here in the fortress, so they must either fight or make their escape—if they can, which, as you know, is doubtful. As they are manned by and belong to your friends, it is fitting that I should ask you which course they will prefer to adopt.’ ’I am for fighting at all hazards; and so will they be, I know,’ returned Fumenta, with grim determination. ’You need not put the question to them.’ ’I am glad to hear that, since it accords with my own wishes,’ was Ivanta’s answer. ’I shall take my measures at once in accordance with your decision. But you must take charge of your fleet, and, for the time being, do the best you can at first, as though my yachts were out of it. They are not fitted to bear the brunt of the first attack from heavier craft, but you will find we shall be able to render you help in another way. We can rise higher and manoeuvre better than any airship belonging either to you or to Agrando.’ ’So be it,’ said Fumenta simply. ’We will do our best, sir, rest assured, apart from your yachts; and if you can help us so much the better.’ It was the _Nelda_, the king’s yacht, from which Monck had observed the approach of the hostile squadron. She could soar so high that, by the aid of powerful glasses, the strangers had been sighted at an immense distance. Then, thanks to her swiftness of flight, she had carried the news to the fortress before the foe had appeared above the horizon. When, an hour later, therefore, those in charge of Agrando’s powerful fleet drew near, they found a smaller squadron waiting to give them battle. The oncoming fleet halted, and for a while the hostile forces remained watching each other. Then amongst Agrando’s airships there was seen the flutter of a white flag, which on Mars, as on our own globe, is the generally recognised sign of a desire for a parley. Presently a small pinnace, bearing the white emblem, came flying towards the vessel which Fumenta had made what we should term his ’flagship’—a large-sized craft called by the Martian equivalent for Crescent.
