weeks passed on, and still the Iveniacontinued on her tremendous journey through space to meet the advancing planet Mars. She travelled at a rate which would make the heads of young readers swim if it were set down in figures. Yet she glided on so smoothly that those on board might well have thought she was all the time standing motionless in one place. How this was accomplished was one of those secrets which Monck confessed himself unable to explain. And the same may here be said of some other mysteries which puzzled Mr Armeath not a little. One was, that there was a feeling of weight or gravity on board much the same as upon the Earth. Another puzzle was, how was the supply of air kept always pure and wholesome? These were among the things that Ivanta kept to himself. The Earth sank away into the distance, gradually diminishing in size till it became no larger to the view than the moon when it is full. Then came a time when it looked like a rather large star of a pale-bluish tint.
On board, the time passed, for the most part, pleasantly enough. There was plenty to do – plenty of work and plenty of amusement. King Ivanta was a ruler who believed in the policy of keeping his people busy in one way or another. Every person on board was compelled to give a certain amount of time each day to work or study of some kind; while a certain interval was also set aside for recreations. The latter were of many kinds. There were concerts – for the Martians seemed to be all fond of music – games, somewhat after the style of football, tennis, and other athletic sports; and, not least, military exercises, in which the soldiers took part and contended for prizes. These – which the chums always watched with the utmost interest – often took the form of actual combats. Sometimes they were between two champions, sometimes between parties of fifty or a hundred; and amongst the latter there were often many 'slain' on both sides; but they always came to life a little later, none the worse for the experience.
Then it was that the chums saw the use made of the shields borne by the soldiers, which Gerald had first noticed when he had been a prisoner. They were, as stated, transparent, and it now appeared that they were used as a protection against the mysterious power of the 'tridents,' or 'electric guns.' Just as electricity will not pass through glass, so the curious 'flash' from the tridents could not pass through these shields. The heads, feet, and legs of the combatants, and some other parts of their bodies, were also protected in similar fashion, so that they appeared to be partly dressed in shining armour. They wore helmets, breastplates, and leg and thigh pieces, which looked like glass, yet were not brittle, and which, like the shields, were proof against the power of the tridents.
Thus, a duel between two antagonists equipped in this manner resolved itself, to a great extent, into a trial of skill in the use of the shield. Through it each could see the other; and many were the feints and stratagems resorted to by a practised fighter to get at his foe behind his shield.
Every night King Ivanta held a levee or other Court function, which all who were off duty were free to attend, and at which very curious entertainments were sometimes provided.
Altogether there was no lack either of occupation or amusement during the three months which the voyage lasted.
Gerald and Jack applied themselves assiduously to learn the Martian language, and in this they were joined by Mr Armeath. Then, by way of relaxation, they gained the king's permission to learn the mysteries and use of the trident and shield. Monck fitted them out in suits of the shining armour, and they practised under the instruction of one named Aveena, a young noble of the Court. Thanks to his tuition, they became so expert that they entered for contests before the king, and came off victorious in more than one bout with others of their own age. Silas Zuanstroom was one of those they each vanquished in turn; only with the result, however, of increasing the coldness which had grown up between the two parties of travellers from the Earth.
One day, Gerald met with yet another disagreeable adventure in the Zoo, and again narrowly escaped a terrible death. This time it was a large venomous serpent of vicious and aggressive disposition, which (again by some 'accident') had got loose just about the time when Gerald, unarmed and unsuspicious of danger, was taking his stroll round the cages. Monck came upon him, a little later, clinging to the upper branches of a tall palm-like tree, which the serpent was slowly climbing, bent on reaching him.
This time the engineer reported the matter to the king, who sternly ordered a strict inquiry with the object of finding out who was to blame. But no evidence was forthcoming to show that the occurrence had been other than an accident; and the affair ended in the punishment of one of the keepers in charge for negligence.
But more exciting events were steadily preparing, and began to develop as the voyage went on.
One morning the two chums were called into Armeath's private apartment, where he was awaiting them with Monck. He explained that he had received the king's permission to impart to them an important piece of information. 'I am going to entrust you with a bit of a secret,' said he, 'and I must ask you to regard it as confidential, and say nothing about it to any one – particularly to the Zuanstrooms; which, of course, includes the two lads. Doubtless you have wondered what it was which induced King Ivanta to pay a second visit to our Earth. It is this, that what we call precious stones do not exist naturally in Mars. None were ever seen there until the king brought back a quantity after his first visit.'
Gerald burst into an exclamation. 'Just what I guessed, sir,' he cried. 'I have had that idea in my mind for some time!'
'It was a shrewd guess, lad,' Monck observed. 'The fact is, that once the Martians had set eyes on them they went almost mad over them, and became clamorous for a larger supply to be brought, in order that those who could afford it might be able to purchase some.
'Our gracious master, who is continually thinking what new thing he can do to please his people, determined to pay a second visit to the Earth specially to secure a large supply. Hence his taking up with Zuanstroom, the "Diamond King." But Zuanstroom was not easy to arrange with. When he learned the actual state of the case, he insisted, as a part of the bargain, that my master should promise to bring him over to Mars for a trip, and take him safely back. Nothing less would satisfy him.'
'I see,' said Jack. 'And I suppose his diamonds are on board too – a whole shipload of them, so to speak?'
'Exactly. The greatest load of treasure, I suppose, that has ever been carried on any ship of the air or the sea.'
'But,' said Gerald, 'the Zuanstrooms know all this. Why mustn't we speak to them about it?'
'Because, at this point, I come to my story,' Armeath said, with a half-smile. 'For years I have been experimenting, trying to manufacture precious stones artificially. At last I succeeded in getting diamonds from a certain mineral; only to find, however, that the discovery was almost valueless, because I could not get enough of the particular mineral. I found out that there was some in the island we have been living on, and that was the reason I went there to stay for a time. When, however, I understood what King Ivanta wanted, I told him of my experiments, showed him the results, and he was highly delighted. He said it would be easier and cheaper to manufacture diamonds than to buy them from the Diamond King on his own terms.'
'But how can that be done, sir, if the necessary material is so scarce?' asked practical Jack.
'You shall hear. King Ivanta recognised the mineral, and declares that there is plenty of it to be obtained from the planet Saturn. He saw quantities of it when he was there!'
'Then we are to go to Saturn to obtain a supply; I suppose?' cried Gerald, full of enthusiasm at the prospect of this new and unexpected addition to their programme of adventure.
'That I cannot yet say,' replied Armeath. 'We must hear what the king says.'
'But, sir,' exclaimed Jack, 'you would not think of leaving us alone – stranded – upon a strange planet! Suppose you never came back!'
'It is not a pleasant place to visit; I can tell you that much,' Monck put in. 'Saturn, at the present time, is in the stage which the scientists tell us the Earth was in, ages ago, when the great antediluvian monsters existed. Those monsters – or similar ones – are alive now on Saturn; and terrible creatures they are, I can assure you! The amalpi– the unicorn-like animal which hunted you, Master Gerald – is one which we managed to capture and bring back from Saturn. But it is small and almost harmless compared with some
