First, there was the subject seldom absent from his mind, the question, what he was to do henceforth in life; to what occupation he should devote himself, and in what direction he had best seek it. He was far from rich, and every day of indecision and inaction made his inheritance a source of greater anxiety to him. As often as he began to consider how to increase this inheritance, or to lay it by, so often his misgiving that there was some one with an unsatisfied claim upon his justice, returned; and that alone was a subject to outlast the longest walk. Again, there was the subject of his relations with his mother, which were now upon an equable and peaceful but never confidential footing, and whom he saw several times a week. Little Dorrit was a leading and a constant subject: for the circumstances of his life, united to those of her own story, presented the little creature to him as the only person between whom and himself there were ties of innocent reliance on one hand, and affectionate protection on the other; ties of compassion, respect, unselfish interest, gratitude, and pity. Thinking of her, and of the possibility of her father's release from prison by the unbarring hand of death--the only change of circumstance he could foresee that might enable him to be such a friend to her as he wished to be, by altering her whole manner of life, smoothing her rough road, and giving her a home--he regarded her, in that perspective, as his adopted daughter, his poor child of the Marshalsea hushed to rest. If there were a last subject in his thoughts, and it lay towards Twickenham, its form was so indefinite that it was little more than the pervading atmosphere in which these other subjects floated before him.

He had crossed the heath and was leaving it behind when he gained upon a figure which had been in advance of him for some time, and which, as he gained upon it, he thought he knew. He derived this impression from something in the turn of the head, and in the figure's action of consideration, as it went on at a sufficiently sturdy walk. But when the man--for it was a man's figure--pushed his hat up at the back of his head, and stopped to consider some object before him, he knew it to be Daniel Doyce.

'How do you do, Mr Doyce?' said Clennam, overtaking him. 'I am glad to see you again, and in a healthier place than the Circumlocution Office.'

'Ha! Mr Meagles's friend!' exclaimed that public criminal, coming out of some mental combinations he had been making, and offering his hand. 'I am glad to see you, sir. Will you excuse me if I forget your name?'

'Readily. It's not a celebrated name. It's not Barnacle.'

'No, no,' said Daniel, laughing. 'And now I know what it is. It's Clennam. How do you do, Mr Clennam?'

'I have some hope,' said Arthur, as they walked on together, 'that we may be going to the same place, Mr Doyce.'

'Meaning Twickenham?' returned Daniel. 'I am glad to hear it.'
