On going below to attend the Captain's dinner Stephen had left a dismal deck, full of tired, deeply disappointed men, gasping-hot, apt to quarrel with one another and with the Turks; he returned to find sunny faces, affectionate looks, a holiday atmosphere, laughter fore and aft, his bell beautifully put together, ready to be swung clear of the rail and lowered; its glass had been newly polished and a series of beckets within held six loaded pistols and two boarding-pikes, while a variety of hooks, tackles, lines and ropes lay neatly coiled upon the bench. But the laughter stopped and the mood changed entirely when what had been in prospect became immediate reality. 'Should you not wait until the evening, sir?' asked Bonden as Stephen prepared to get into the bell, and it was clear from their serious, concerned faces that he was speaking for a good many of the crew.

'Nonsense,' said Stephen. 'Remember, now, at two fathoms we pause and renew the air.'

'Perhaps we should try with a couple of midshipmen first,' said the purser.

'Mr Martin, pray take your seat in the usual place,' said Stephen. 'James Ogle,' - this to the man in charge of the pair of barrels - 'mind you do not let us want for air.'

There was no fear of that. The cranks whipped round as though for James Ogle's own salvation, and the bell had not sunk its first gentle two fathoms before the fresh air was there, ready to be let in. Everything that anxious care on board could do was done, and twenty picked hands with muskets lined the side; but there was little that could be done apart from tending the tackles, and there was not a man aboard who did not feel sick with apprehension when a huge fish, thirty-five to forty feet long, glided between them and the bell, far too deep for any musket. It turned above the glass, darkening the day. 'That must be the big carcharodon,' said Stephen, looking up. 'Let us see what he will make of this.' He reached for the cock and let out a furious bubbling stream of used air. In a single swift movement the shark turned its vast bulk and was seen no more.

'I wish he had stayed a little longer,' said Martin, reaching down for the hose from the next barrel. 'Poggius says he is excessively rare.' He raised the tube and the compressed air hissed into the descending bell, driving the few inches of water that had entered it down to the rim. 'I believe this is the clearest day we have ever had.'

'I am sure you are right. I never have made an ascent in an air balloon, alas, but I imagine it to give this same immaterial floating even dreamlike sensation. There is a small Chlamys heterodontus.'

A few minutes later the bell settled on the galley's deck, neatly placed abaft the rowers' benches and just over the after hatchway, whose grating had floated off.

Time passed: interminable for those above, quite short for those below.

'What can they be at?' cried Jack at last. 'What can they be at?' There was no signal from the bell, no sign of life apart from the streams of air that made the surface boil and froth from time to time. 'How I wish I had never let them go.'

'Perhaps,' said Martin, after their tenth attempt at connecting line, hook and tackle, 'perhaps we might send up a message desiring them to lower down a stout hook already tied to its necessary ropes and pulleys.'

'I am very unwilling that they should suppose I am not the complete seaman,' said Stephen. 'Let us try just once again.'

'There are two young tiger-sharks peering through the glass,' observed Martin.

'No doubt, no doubt,' said Stephen testily. 'I do beg you will pay attention, and pass the rope through this loop, while I hold it open.'

Through the loop or not, the assembly would not hold, and the shameful message, written with an iron stylus on a small sheet of lead, was obliged to be sent up.

A perfectly simple, perfectly foolproof hook came down. Working it from the Niobe's deck called for much more labour, but the hands who tailed on to the fall cared nothing for that, although the temperature was now a humid hundred and twenty-eight degrees under the awnings, and presently great stretches of the galley's deck came floating to the surface. It was so thin and light, apart from the beams fore and aft of the masts, that a grapnel could pull it apart; and the beams themselves yielded to the first heave of the Niobe's kedge. The entire hull lay open, and although by now the water was so troubled that nothing could be clearly made out from the ship, the bell sent up a message 'We see small rectangular chests, or large boxes, apparently sealed. If you will move us a yard to the left we can reach the nearest, which we shall attach to a rope.'

'I should never have believed that so small a bulk could be so heavy,' said Martin as they lifted it across to the middle of the bell, where there was most light. 'Do you see that the French seals, with the Gallic cock, are red, while the Arabic are green?'

'So they are, joy. Now if you will tilt it up, I will pass the rope around twice.'

'No, no. We must do it up at both ends, like a parcel. I do wish the Navy had ordinary string: this thick rope is so plaguey stiff and hard to tie. Do you think this bow will answer?'

'Admirably well,' said Stephen. 'Let us slide it out under the rim again, and give the signal.'

'Bell signals heave away, sir, if you please,' said Bonden.

'Carry on, then,' said Jack, 'but handsomely, handsomely.'

At this time the bell was emitting no bubbles. The chest could be seen, at first dimly, then quite clear, rising slowly through the water; and the grinning hands perceived its weight.

'Oh my God the knot's slipping,' cried Mowett. 'Bear a hand, bear a hand, bear a... Hell and death.'

On reaching the surface the chest glided through its bonds and plunged free, directly over the bell. 'If it hits the glass they are dished,' thought Jack, following its course with appalled anxiety while at the same time he roared 'Stand by the bell tackle-fall - jump to it.'

The plummeting chest missed the glass by inches, striking the bell an echoing blow and landing by its rim. 'The next time we must cross the knot the other way,' said Martin.

'I cannot stand this any longer,' said Jack. 'I shall go down and make them fast myself. Mr Hollar, give me some spun-yarn and marline. Raise the bell.'

The bell came up; it swung dripping inboard, and Stephen and Martin stepped out, cheered by one and all. 'I am afraid we did not tie it quite tight enough,' said Stephen.

'Not at all. You did splendidly, Doctor. Mr Martin, I congratulate you with all my heart. But perhaps thisjime I will take your place. Every man to his trade, you know, and the cook to the foresheet.'

A gale of laughter followed this, and his shipmates thumped the cook on the back: they were in such tearing spirits they could scarcely contain themselves. Captain Aubrey, on the other hand, had to overcome a very real repugnance as he mounted the bell and sat on the bench; his look of flushed triumphant happiness faded to sobriety and it was all he could do to keep it to that; he hated being confined- he would not have gone into a coal-mine for anything in the world- and during their passage down he was obliged to repress a very strong irrational urge to escape whatever the cost. However, their pause in midwater, the business of renewing the air and letting out the old, kept him occupied; and when he was standing on the galley's floor he felt somewhat better - at least in full control.

'We have returned to our old place exactly,' said Stephen. 'Here is the very one we dropped. Let us pull it in.'

'Are they all like this?' asked Jack, looking at the stout chest with its deeply recessed ends.

'As far as I can see they are all exactly the same. Look under the rim - there is a whole range of them running forward.'
