'Lock ho! Lock!' It was a light night, and a barge coming down summoned him out of a long doze. In due course he had let the barge through and was alone again, looking to the closing of his gates, when Bradley Headstone appeared before him, standing on the brink of the Lock.

'Halloa!' said Riderhood. 'Back a' ready, T'otherest?'

'He has put up for the night, at an Angler's Inn,' was the fatigued and hoarse reply. 'He goes on, up the river, at six in the morning. I have come back for a couple of hours' rest.'

'You want 'em,' said Riderhood, making towards the schoolmaster by his plank bridge.

'I don't want them,' returned Bradley, irritably, 'because I would rather not have them, but would much prefer to follow him all night. However, if he won't lead, I can't follow. I have been waiting about, until I could discover, for a certainty, at what time he starts; if I couldn't have made sure of it, I should have stayed there.--This would be a bad pit for a man to be flung into with his hands tied. These slippery smooth walls would give him no chance. And I suppose those gates would suck him down?'

'Suck him down, or swaller him up, he wouldn't get out,' said Riderhood. 'Not even, if his hands warn't tied, he wouldn't. Shut him in at both ends, and I'd give him a pint o' old ale ever to come up to me standing here.'

Bradley looked down with a ghastly relish. 'You run about the brink, and run across it, in this uncertain light, on a few inches width of rotten wood,' said he. 'I wonder you have no thought of being drowned.'

'I can't be!' said Riderhood.

'You can't be drowned?'

'No!' said Riderhood, shaking his head with an air of thorough conviction, 'it's well known. I've been brought out o' drowning, and I can't be drowned. I wouldn't have that there busted B'lowbridger aware on it, or her people might make it tell agin' the damages I mean to get. But it's well known to water-side characters like myself, that him as has been brought out o drowning, can never be drowned.'

Bradley smiled sourly at the ignorance he would have corrected in one of his pupils, and continued to look down into the water, as if the place had a gloomy fascination for him.

'You seem to like it,' said Riderhood.

He took no notice, but stood looking down, as if he had not heard the words. There was a very dark expression on his face; an expression that the Rogue found it hard to understand. It was fierce, and full of purpose; but the purpose might have been as much against himself as against another. If he had stepped back for a spring, taken a leap, and thrown himself in, it would have been no surprising sequel to the look. Perhaps his troubled soul, set upon some violence, did hover for the moment between that violence and another.

'Didn't you say,' asked Riderhood, after watching him for a while with a sidelong glance, 'as you had come back for a couple o' hours' rest?' But, even then he had to jog him with his elbow before he answered.

'Eh? Yes.'

'Hadn't you better come in and take your couple o' hours' rest?'

'Thank you. Yes.'

With the look of one just awakened, he followed Riderhood into the Lock-house, where the latter produced from a cupboard some cold salt beef and half a loaf, some gin in a bottle, and some water in a jug. The last he brought in, cool and dripping, from the river.

'There, T'otherest,' said Riderhood, stooping over him to put it on the table. 'You'd better take a bite and a sup, afore you takes your snooze.' The draggling ends of the red neckerchief caught the schoolmaster's eyes. Riderhood saw him look at it.

'Oh!' thought that worthy. 'You're a-taking notice, are you? Come! You shall have a good squint at it then.' With which reflection he sat down on the other side of the table, threw open his vest, and made a pretence of re-tying the neckerchief with much deliberation.

Bradley ate and drank. As he sat at his platter and mug, Riderhood saw him, again and yet again, steal a look at the neckerchief, as if he were correcting his slow observation and prompting his sluggish memory.
