      It would be almost impossible for us of the present day to form any adequate estimate of the thrill of horror and consternation which this brief and temperately-worded narration of the mysterious loss of the three transports sent through the world of the twenty-first century. Not only was it the first event of the kind that had occurred within the memory of living men, but, saving the loss of the Ithuriel, it was the first dark cloud that had appeared in the clear heaven of peace and prosperity for more than a hundred and twenty years.

      But terrible as was the state of excitement and anxiety into which it threw the nations of the world, it gave place to a still deeper horror and bewilderment when day after day passed and no tidings were received of the three submarine squadrons, consisting of three vessels each, which had been sent to inquire into the fate of the transports. They dived beneath the waves of the Indian Ocean and the Atlantic, and that was the last that was ever seen of them.

      Month after month went by, every week bringing news of some fresh calamity at sea—of the disappearance of transport after transport along the great routes of ocean travel, of squadron after squadron of submarine cruisers which plunged into the abysses of the sea to discover and attack the mysterious enemy of mankind that lay hidden in the depths, and which never reappeared on the surface. Whether they were captured or destroyed it was impossible to say, simply because no member of their crews ever returned to tell the tale.

      Whatever doubt there had been as to the existence or hostile nature of this ocean terror that was paralysing the trade of the world was speedily set at rest by a discovery made in the spring of the year 2032 by a party of divers who descended to repair a fault in one of the Atlantic cables about two hundred miles west of Ireland.

      There, lying in the Atlantic ooze, they found the shattered fragments of the Sirius, a transport which had disappeared about a month before. The great hull of the splendid vessel had been torn asunder by some explosive of tremendous power, and, more than this, her hold had been rifled of all its treasure and the most valuable portions of its cargo. After this there no longer remained any doubt that the depths of the ocean were the hunting-ground of some foe of society, one at least of whose objects was plunder.

      The President and Council of Aeria found themselves at last confronted and baffled by an enemy who could neither be seen nor reached in his hiding-place, wherever it might be, beneath the surface of the waters. Thousands of lives had been sacrificed, and treasure in millions had been lost by the end of the first year of what men had now come to call the New Terror.

      New fleets of submarine cruisers were built and held in readiness in all the great ports of the world, and these scoured the ocean depths in all directions with no further result than the swift and silent annihilation of vessel after vessel by some power which struck irresistibly out of the darkness and then vanished the moment that the blow had been delivered.

      As yet, however, no enemy appeared on land or in the air, nor were any tidings heard of the lost Ithuriel, or her captain and lieutenant. The Aerians had replaced her with ten almost identical vessels and had raised the strength of their navy to two hundred and fifty vessels, one hundred of which were kept in readiness in Aeria, while the other hundred and fifty were distributed in small squadrons at twenty-four stations, half of which were in the Western hemisphere and half in the Eastern.

      The submarine warfare had now practically ceased. Nearly two hundred vessels belonging to Aeria, Britain, and America, had been captured or destroyed by an enemy which at the period at which this portion of the narrative opens was as supreme throughout the realm of the waters as the Aerians were in the air. To the menace of the air-ships this hidden foe replied by severing all the oceanic cables and paralysing the communication of the world save overland and through the air.

      Thus, at the end of six years after the capture of the Ithuriel by Olga Romanoff more than half the work of those who had brought peace on earth after the Armageddon of 1904 had been undone. All over the world, not even excepting in Aeria, men lived in a state of constant anxiety and apprehension, not knowing where or how their invisible enemy would strike them next.

      The Masters of the World were supreme no longer, for a new power had arisen which, within the limits of the seas, had proved itself stronger than they were. Communication between continent and continent had almost ceased, save where the Aerian air-ships were employed. In six short years the peace of the world had been destroyed and the stability of society shaken.

      Among the nations of Anglo-Saxondom the change had manifested itself by a swift decadence into the worst forms of unbridled democracy. Men’s minds were unhinged, and the most extravagant opinions found acceptance.

      Parliaments had already been made annual and were fast sinking into machines for registering the ever-changing opinions of rival factions and their leaders. Sovereigns and presidents were little better than popular puppets existing on sufferance. In short, all that Paul Romanoff had prophesied was coming to pass more rapidly than even he had expected so far as the area of the Anglo-Saxon Federation was concerned.

      In the Moslem Empire affairs were different, but no less threatening. The Sultan Khalid the Magnificent, as he was justly styled by his admirers, saw clearly that the time must come when this mysterious enemy would emerge from the waters and attempt the conquest of the land, and for three years past he had been manufacturing weapons and forming armies against the day of battle which he considered inevitable, and which he longed for rather than dreaded.

      Thus, while Anglo-Saxondom was lapsing into the anarchy of unrestrained democracy, the Moslem monarch was preparing to take advantage of the issue of events which, skilfully turned to account, might one day make him master of the world.

      Such was the condition of affairs throughout the world on the 1st of May 2036, and then the long-expected came in strange and terrible shape. At midnight a blaze of light was seen far up in the sky over the city of Aeria. A moment later something that must have been a small block of metal fell from a tremendous height in the square in the centre of the city, and was shivered to fragments by the force of its fall.

      On the splintered pavement where it fell was found a little roll of parchment addressed to the President. It was taken to him, and he opened it and read these words:—

      To Alan Arnold, President of Aeria.

      If you want your son Alan and his friend Alexis, go and look for them on an island which you will find near the intersection of the 40th parallel of south latitude and the 120th meridian of west longitude in the South Pacific. They have served my turn, and I have done with them. Perhaps they will be able to tell you how I have conquered the Empire of the Sea. Before long I shall have wrested the Empire of the Air from you as well.
