TWENTY-FOUR hours after she had reached Mount Terror the _Narwhal_ came into the inner basin of Christmas Harbour, running easily along the surface, with the red flag flying at her flagstaff. The news spread rapidly through the little settlement, the dwellers in which had been wondering greatly at her sudden disappearance, and there was quite a crowd on the jetty as she ran alongside. Max Ernstein was among it, and as the battleship came to a standstill he saw to his amazement Alan spring ashore and come towards him with outstretched hands. “Why, what does this mean?” he said, as he grasped his hand. “I thought you told me you were never going to leave the _Narwhal_ until”-- “Until we had done what we have done,” said Alan with a laugh, as he returned his hand-clasp with a grip that made the bones crack. “We have destroyed a good half of what remained of the Russian sea navy, and, what’s more, we’ve blown up the entrance to their submarine dockyard, and completely crippled them as far as building or equipping new vessels is concerned until they can find a new harbour.” “Magnificent!” exclaimed Ernstein. “Glorious! You’ll be wearing the golden wings again in forty-eight hours.” “If I am,” said Alan, flushing with pleasure at the thought, “the credit will be due to Alexis, and not to me. It was his idea entirely. But never mind that now. We’ve suffered rather badly, and only just escaped with our lives. Five out of six of the _Narwhal’s_ crew are disabled, and I want you to get them out and send them away to Aeria as soon as possible. Meanwhile Alexis and I will write our despatch to the Council.” His instructions were obeyed at once, and the invalids were transferred to the _Vega_, the air-ship that was to convey them to Aeria, and in her luxurious state-rooms their hurts were attended to by the best skill on the island while the despatch was being drawn up. It was brief, plain, almost formal in language, and confined entirely to statement of bare fact, and in little more than an hour after the arrival of the _Narwhal_ at Christmas Harbour the _Vega_ had risen into the air, and was speeding on her way towards Aeria. Meanwhile the news of the daring venture and brilliant exploits of Alan and Alexis and their comrades spread like wildfire through the island, and everyone who was not engaged on duties that could not be left came to the settlement to see and congratulate the two heroes of the hour, whose strange and romantic fate, so well known to every Aerian, had thus suddenly been glorified by the triumph of the genius and daring which had proved capable of wresting victory from defeat and glory from misfortune.
