‘How long’s this island going to remain in the road?’ asked Head; ‘do it always mean to stop here? They’ll have to put a lighthouse upon it.’

‘Do you think this hulk would float, captain,’ I called out, ‘if the head of this rock were to subside, as Johnson yonder suggests?’

‘Well, she ain’t buried, sir!’ he exclaimed; ‘there’s nothen to stop her from remaining behind, that I can see, if she’s buoyant enough to swim. If she’s pretty nigh hollow she’ll do it, I allow; for look at the shape of her. As there’s a chance of such a thing, then, when she’s done draining, we’d better plug the holes we’ve made.’

‘I’ll see to that,’ said Dowling; ‘there’s no leaving of her with me till I’ve seen what’s inside of her.’

‘It will be proper to keep a look-out, I suppose, sir,’ said Finn.

‘Why, yes,’ I answered; ‘the night is silent enough now, but there may come a breeze of wind at any minute and bring along a ship, and one pair of eyes at least must be on the watch.’

‘There’s nothen aboard to make a flare with,’ said Cutbill; ‘a pity. This here’s a speck of rock to miss a short way off in the dark.’
