called at once if anything fresh occurred.
His wards remained on the watch, however, and with them their two sailor hands, Tom Clinch and Bob Reid; and in due course the moon went down and it became quite dark. Then, behold! there was another wonder to be added to the rest – the whole great mass became luminous! Not only that, but queer shadows came and went upon it, as though something were in motion upon the surface or just beneath it.
The news of this being conveyed to Armeath brought him out again; but he could not account to his own satisfaction for this new phase.
'It may be that it is composed of some highly phosphorescent mineral,' was the only explanation he could suggest.
At last the morning dawned, and, immediately it was light, Armeath and his two young companions, without waiting for breakfast, put off in a boat, with the two sailors, to examine the meteorite more closely.
It was still there, but the slight wind had drifted it up to a sandy ledge close inshore, and it appeared to be now resting on the sand.
They rowed up to it and were not a little surprised to find that the whole mass was perfectly smooth like glass. Still more mystifying was it to see that there were bands at regular intervals extending 'from stem to starn,' as Tom expressed it, 'jest for all the world like the hull of a great boat.'
They rowed all round it, their wonderment and astonishment growing all the time. They computed that it must be considerably over a thousand feet in length, by, perhaps, a hundred feet in diameter.
Suddenly Gerald uttered a loud exclamation. Jack, glancing at him, saw that he was pointing to a place in the side of the mass and staring at it as though his eyes were about to start out of his head.
'What on earth's up, old man?' he asked in alarm. 'Have you got an attack of nerves again, or' —
'Jack!' cried Gerald, seizing his chum's arm, 'd-didn't you see – didn't you see them?'
'Them – what – who?' asked Jack, bewildered.
'People – men – moving about! I declare that I saw some men moving about inside the – the – thing!'
'You 're barmy, my good Gerald! This little astronomical raree-show has been too much for those imaginative nerves of yours. I see nothing. Perhaps you saw shadows thrown by some birds flying overhead.'
'No, oh no! A thousand times no! I tell you I saw people – two or three – moving about inside that smooth, slippery surface. They were very dim and shadowy, it is true, but they were there. I saw them just as one might see anything through very thick, semi-opaque glass. What does it mean? I tell you it's uncanny! There's some strange mystery about it all. This thing is not what it seems to be. What, in the name of all that is wonderful, does it mean?'
Jack looked at the smooth, shining sides which rose from the water and towered up high in the air. But he could see nothing to account for Gerald's wild words; and he then glanced inquiringly, with real alarm and trouble in his eyes, at Armeath.
'I am afraid,' said the scientist, with a grave smile, 'that Gerald is letting his exuberant imagination run away with him this morning. I confess I see nothing of the kind he described. It must have been some strange effect of the rays of the sun, which is not very high yet, striking at an angle upon these remarkable, shining sides.'
Gerald shook his head impatiently, but made no verbal reply; and they rowed round and round the phenomenon, without finding anything to satisfy their curiosity. Armeath examined the smooth sides closely, sometimes through a magnifying glass. He even tried to chip off a piece with a hammer and a chisel; but it was so hard that he could make no impression upon it, and so slippery that his chisel glanced off and flew from his hand into the sea.
After a good deal of rowing to and fro, and a considerable amount of critical examination, which threw not the slightest light upon the puzzling lump of mystery, it was decided to return to shore for their breakfast.
Even over their meal, however, their talk continued to run upon the all-engrossing subject. Jack rallied his chum unmercifully upon the extraordinary statement he had made; but Gerald refused to admit that he might have been mistaken.
'I saw what I told you!' he persisted doggedly. 'I may be a bit of a dreamer at times, but I don't "see visions" to that extent. No, there is some awful, inscrutable, incredible mystery about it all! Well, we 'll wait and see. We shall find out, I suppose, in good time.'
With such discussions and speculations the day passed, without bringing anything fresh in the way of enlightenment.
When evening came, Jack declared his fixed resolution not to allow the puzzle to deprive him of another night's sleep. After supper, therefore, he went off incontinently to bed; and as Armeath shut himself up as usual, Gerald was left to himself.
Still restless and perplexed, dissatisfied with the explanations and theories which had been propounded, Gerald felt no inclination to 'turn in.' Something within him – some vague impulse he could not analyse, above all, the recollection of the mysterious, shadowy figures he believed he had seen through the semi-transparent 'shell,' as Jack now called it – urged him to remain on the watch.
'As Mr Armeath says,' he thought to himself, 'if a wind were to spring up it might be gone by to-morrow. We may as well, therefore, keep an eye on it while it is here, and watch its departure when it goes.'
In order to carry out his idea, he required a reliable assistant, and this he found in Tom Clinch. Not only had Tom known Gerald all his life, as already stated, but he had served his father before him, and he had now transferred his devotion to the son. When, therefore, the young fellow sought him out and told him what he required, Tom was ready enough to lend his aid.
'We 'll keep a watch, Mr Gerald,' he responded, 'turn and turn about, all night, an' have the boat ready in case we wants it. Fur my part, I think ye're only actin' cautious-like. Nobody can tell what's goin' to happen next when things like this once begin fallin' from the skies. I've 'eerd it said as 'ow theer's supposed to be a great bear, an' scorpions, an' crabs in the sky. An' after this, who can say but they might come a-rainin' down on us an' eat us all up in our sleep?'
Honest Tom had heard vaguely of the constellations of stars called by those names, and had very loose notions as to what they meant.
'Well, I hope it won't be as bad as that,' Gerald answered with a smile. 'But I shall be very glad of your company on my night-watch, all the same.'
So it was arranged; and the two betook themselves to a part of the shore where there was a cave which had been utilised as a boathouse, and here they began their watch.
The night turned out as fine as the previous one, except that there were a few drifting clouds which now and again obscured the light of the moon. There was scarcely any breeze, however, and the sea was, as Tom put it, 'as calm and still as a pint of stale beer.'
For a long time nothing occurred, though they kept up their watch till the moon had set, and it had become quite dark. Then they saw again the luminous appearance which they had noticed before.
'Now this is what I want to investigate, Tom,' said Gerald. 'Get out the boat quickly, and let us pull close up as silently as we can.'
The boat, which had been placed ready for launching, was slipped into the water, Gerald putting in the stern a dark lantern, which he had lighted.
Like a gliding shadow, the boat and her two occupants – the sailor rowing and Gerald steering – approached the huge 'meteorite,' now all aglow with a strange, dim light. The oars, well greased, made no sound, and they passed silently along the side nearest the shore, rounded the end, and were making their way back upon the outer side, when Gerald put a hand upon his companion as a signal to stop rowing.
They were then about the centre of the great mass, on the side which was away from the shore and faced the sea. There the boat remained stationary, Gerald staring intently at the curious shimmering wall which towered up at a distance of twenty or thirty feet.
'See, Tom! Look!' he suddenly whispered excitedly. 'See! There are the shadows – the forms of people! There! Now, who was right?'
'Heaven defend us!' breathed Tom fervently. 'Whatever do it
