recorded in the last chapter. King Ivanta had been to Europe and finished the business he had in hand – for it was generally understood, amongst those who knew of his presence on the Earth, that he had come here on his second visit for some definite purpose. What the purpose was remained for the present a secret confined to the Martian monarch himself and the few he chose to take into his confidence.
Amongst those who shared the secret Mr Armeath was probably one; for he had grown high in favour with the illustrious traveller, and had been invited to accompany him in the forthcoming trip to Mars and back. He had also been accorded the privilege of taking with him his two wards Gerald and Jack, and his two servitors Tom Clinch and Bob Reid; and the latter, loyal and faithful followers that they were, had not shrunk from the risks of the adventure.
There were some other passengers also – namely, Amos Zuanstroom the multi-millionaire (the well-known 'Diamond King'), his son Silas (who was about the same age as Jack), and a much younger lad, named Freddy Whitcomb, his nephew.
Why King Ivanta should choose these particular persons from all the millions of inhabitants of the Earth was another matter which was wrapped in mystery, and which, for the time being, he kept strictly to himself.
As the engineer Mr Monck had predicted, Gerald had good reason to congratulate himself upon the fortunate chance which had enabled him to render so great a service to the Martian king. The latter had shown himself extremely grateful, and had conferred upon the young fellow many marks of his favour. In particular, he had confirmed the offer Mr Monck had made, and had graciously extended it, as stated, to his guardian and his chum.
And now, behold them all, then, on board the Ivenia, the colossal 'chariot of the skies,' awaiting the moment when she should rise in the air and commence her tremendous journey.
She lay in a sort of natural harbour in the island, a spacious salt-water lake almost landlocked.
From this she presently rose easily and smoothly, like a huge bird wending its way upwards in a series of graceful circles. Like a bird, too, she had at first enormous wings spread out to the air. But after a time, as she gained the upper air, these were folded away, the upper covering was replaced, and she became once more the great, egg-shaped mass she had appeared when she had arrived beside the island. How, afterwards, she continued to force her way upwards against the attraction of the Earth, was King Ivanta's own secret. It was believed that he had discovered a means of using the sun's more powerful attractive force, and so controlling it as to make it do whatever he required; but that was probably only a guess. What is certain is that the whole structure continued to rise steadily and smoothly upwards, till presently Gerald and Jack were called by Mr Armeath and the engineer, Mr Monck, to come to a sort of periscope, from which they could take their last look at the Earth.
They stepped forward and stared through the opening in startled wonder. There, they saw our globe, looking like an enormous ball. The great airship itself was perfectly steady, and appeared to be absolutely motionless. Not a tremor was to be felt, and it seemed as though it was the Earth which was receding from them at a rapid rate, not they from the Earth. No longer, however, could they make out details upon its surface; the distance was already too great. All they could distinguish were the respective masses of land and water, broadly mapped and marked out as they are upon a school globe representing the Earth. The side they were looking at showed the New World – the great continents of North and South America and the oceans surrounding them – and that was all.
Who shall attempt to describe their feelings, or guess their thoughts, as they stood there gazing at this strange appearance of the planet upon which they had lived all their lives? Probably they then for the first time fully realised the actual nature of the risks they were running; and it is more than likely that they were wondering whether they were looking their last upon the Earth, as they watched it sinking silently away into the immeasurable distance!
CHAPTER VIII
A NARROW ESCAPE
The first part of the time which followed upon the departure from the Earth of the Ivenia on her long journey through space was one of great enjoyment to the two chums. The marvels and mysteries of the great airship – or aerostat, as Mr Armeath preferred to call her – seemed to be inexhaustible. 'Every day' the young people found something new and strange, to puzzle over. Every time they moved about they came upon some unexpected revelation of the wondrous inventions and contrivances which it had been necessary to bring to perfection before the great machine could start upon the adventurous journeys she had undertaken.
The above words, 'every day,' require an explanation. Of course, once they were really out in 'the realms of starry space,' there were really no alternations of day and night, for the sun shone upon them continuously. But within the aerostat artificial nights, so to speak, were produced by drawing huge screens across the semi-transparent outer casing.
Mr Monck explained this to the young voyagers, giving them, incidentally, a little lecture, as it were, in astronomy and general science; and on this occasion he had as his auditors all four of the young passengers – including, that is to say, the two cousins, Silas and Freddy.
'I expect you all know,' he said, 'that out in what is called space, where there is no atmosphere – no air – the sun's rays seem to have no heat. The cold there is most intense – far greater than anything ever experienced upon Earth. You feel the sun's rays warm on your globe because they pass through the Earth's atmosphere, which acts like a lens or magnifying-glass. Here the same effect is obtained by passing them through the wonderful semi-transparent metal of which the outer shell of the airship is composed. It is harder than the hardest steel, yet almost transparent like glass, without being brittle, while it is far lighter than aluminium. It was discovered by King Ivanta, and is called "ivantium" after him. He found that when the sun's rays were passed through it the result was exactly the same as when they pass through the atmosphere of the Earth or of Mars. That is how it is we are so warm and comfortable on board here. But for the discovery of that metal such a journey as we are taking would be impossible. We should be frozen to death.'
'Then there is no need to have day and night unless you like,' Freddy observed, his blue eyes opening in surprise. He was a fair, good-looking youngster, and a great favourite with Monck and the chums.
'No, my lad. But King Ivanta considers it best to keep up the same habits as those you and his people are all accustomed to "at home;" for Mars turns on its axis in about the same time as the Earth – namely, twenty-four hours or thereabouts. That is to say, the average day on Mars is just about the same length as the average day on the Earth.'
On many other occasions, when he had the time and opportunity, the good-natured engineer 'trotted them round' and explained to the young people, in similar fashion, the why and the wherefore of many of the things that puzzled them – so far, that is, as he himself understood them. But as to a great many, and those some of the most surprising, he was obliged to confess his own entire ignorance.
'There are most essential secrets connected with the structure and working of this remarkable "chariot of the skies" which no one but my master understands, and he takes good care to keep them to himself,' he declared. 'When you reach Mars, for instance, you will see there numerous airships and flying-machines of many kinds. It has, indeed, been much easier for the Martians to learn to build such contrivances than for the dwellers upon the Earth, because, as I have before mentioned, the air upon Mars is so much denser. But though you will see many such things flying about, you will not see one that can compare with this; not one that can venture out into space, or, indeed, very far above the surface of the planet.'
Often Mr Armeath accompanied the young people, and listened with interest to the engineer's explanations; for, scientist though he was, he found he had almost as much to learn in their new surroundings as they had.
Truly, the great airship was a wonder from every point of view. It may assist readers to understand the stupendous scale upon which she had been designed if it is explained that she was more than twice the size of Britain's great warship the Dreadnought. But nothing less in bulk would have been of any use if we consider the tremendous strength required, and the accommodation necessary for the number of people she carried – of whom there were between two and three thousand. In addition, room had to be provided
