a considerable circuit by the high road

MY nearest way to Yarmouth, in coming back from these long walks, was by a ferry. It landed me on the flat between the town and the sea, which I could make straight across, and so save myself a considerable circuit by the high road. Mr. Peggotty's house being on that waste-place, and not a hundred yards out of my track, I always looked in as I went by. Steerforth was pretty sure to be there expecting me, and we went on together through the frosty air and gathering fog towards the twinkling lights of the town.
One dark evening, when I was later than usual - for I had, that day, been making my parting visit to Blunderstone, as we were now about to return home - I found him alone in Mr. Peggotty's house, sitting thoughtfully before the fire. He was so intent upon his own reflections that he was quite unconscious of my approach. This, indeed, he might easily have been if he had been less absorbed, for footsteps fell noiselessly on the sandy ground outside; but even my entrance failed to rouse him. I was standing close to him, looking at him; and still, with a heavy brow, he was lost in his meditations.
He gave such a start when I put my hand upon his shoulder, that he made me start too. I was so confounded by the alteration in him, that at first I could only observe him in silence, as he stood leaning his head upon his hand, and looking gloomily down at the fire. At length I begged him, with all the earnestness I felt, to tell me what had occurred to cross him so unusually, and to let me sympathize with him, if I could not hope to advise him. Before I had well concluded, he began to laugh - fretfully at first, but soon with returning gaiety. I am not about to be hipped again, David; but I tell you, my good fellow, once more, that it would have been well for me (and for more than me) if I had had a steadfast and judicious father!'
His face was always full of expression, but I never saw it express such a dark kind of earnestness as when he said these words, with his glance bent on the fire. The advent of Mrs. Gummidge with a basket, explained how the house had happened to be empty. She had hurried out to buy something that was needed, against Mr. Peggotty's return with the tide; and had left the door open in the meanwhile, lest Ham and little Em'ly, with whom it was an early night, should come home while she was gone. Steerforth, after very much improving Mrs. Gummidge's spirits by a cheerful salutation and a jocose embrace, took my arm, and hurried me away.
He had improved his own spirits, no less than Mrs. Gummidge's, for they were again at their usual flow, and he was full of vivacious conversation as we went along.
