For three days Aeria kept high festival in honour of the home-coming of the son of the President and his companion in exile, but for all that there was sterner business in hand than merry-making for those in authority. Save in the almost impossible event of overtures of peace being received from the Sultan, war which, in the nature of the circumstances, could hardly fail to be universal, would actually begin at daybreak on the 16th of May, that is to say in five days after the return of Alan and Alexis.

The greater part, therefore, even of the days of rejoicing was really spent in hard work by those upon whom had devolved the tremendous responsibility of counteracting as far as was possible the designs of conquest and oppression to which Olga Romanoff, by means of her fatal beauty and subtle diplomacy, had succeeded in irrevocably committing Khalid the Magnificent.

Early on the morning of the day following the reinvestiture of Alan and Alexis with the symbols of Aerian citizenship a council of war was held in the President’s palace, which was attended by all the members of the ruling Council, the chief engineers of the settlement, and the admirals in command of the aerial and sea navies and the squadrons posted at the various stations throughout the world.

Before this assembly Alan, who had already entered upon the active discharge of his duties as Commander-in-Chief of all the forces of Aeria and the Federation, laid the details of his plans of attack and defence, and invited criticism upon them.

The same day Alan transferred his flag and his crew from the Ithuriel to the Avenger, while Alexis took possession of a splendid vessel of the same type, to which the name Orion had been given, after that of the air-ship commanded by Alan Tremayne in the battle of Armageddon. Alexis, however, had very little difficulty in obtaining the consent of the Council to his substituting another name for this, with the consequence that the prize taken from the enemy resumed her Russian name, and remained in Aeria as a trophy of the skill of her captors.

Perhaps in his heart Alan would have dearly liked to have made a similar change in the name of the Avenger, but it was impossible for him to propose it, situated as he was with regard to Alma.

Alexis and Isma had taken the shortest, and therefore the wisest, course out of the terribly delicate and embarrassing position which had been created by the unholy passions and ruthless treachery of Olga Romanoff. They had tacitly agreed to ignore it in toto, and to begin again where they had left off nearly seven years before, and thus it came to pass that Isma’s own pretty hands spilled the christening wine over the shapely bows of her formidable namesake.

The first use that Alan made of his new ship was to test her immense capabilities to the utmost, so that he might know what demands he might safely make upon her in possible emergencies. He rushed her at full speed round the mountain bulwarks of Aeria, a distance of two hundred and fifty miles, and found that she completed the circuit in just twenty-five minutes, which gave a speed of six hundred miles an hour. Alexis followed, and covered the same distance in twenty-seven minutes and a half in the Isma.

These trials proved that the new Aerian vessels were from fifty to seventy-five miles an hour faster than the models on which their enemies had been building their new fleets—a fact which, unless Olga and her ally had made a corresponding improvement in their battleships, might be expected to have a considerable effect on the issue of the coming war.
