The air felt cold upon the river, but it was a bright day, and the sunshine was very cheering. The tide ran strong, I took care to lose none of it, and our steady stroke carried us on thoroughly well. By imperceptible degrees, as the tide ran out, we lost more and more of the nearer woods and hills, and dropped lower and lower between the muddy banks, but the tide was yet with us when we were off Gravesend. As our charge was wrapped in his cloak, I purposely passed within a boat or two's length of the floating Custom House, and so out to catch the stream, alongside of two emigrant ships, and under the bows of a large transport with troops on the forecastle looking down at us. And soon the tide began to slacken, and the craft lying at anchor to swing, and presently they had all swung round, and the ships that were taking advantage of the new tide to get up to the Pool began to crowd upon us in a fleet, and we kept under the shore, as much out of the strength of the tide now as we could, standing carefully off from low shallows and mudbanks.

     Our oarsmen were so fresh, by dint of having occasionally let her drive with the tide for a minute or two, that a quarter of an hour's rest proved full as much as they wanted. We got ashore among some slippery stones while we ate and drank what we had with us, and looked about. It was like my own marsh country, flat and monotonous, and with a dim horizon; while the winding river turned and turned, and the great floating buoys upon it turned and turned, and everything else seemed stranded and still. For now the last of the fleet of ships was round the last low point we had headed; and the last green barge, straw-laden, with a brown sail, had followed; and some ballast-lighters, shaped like a child's first rude imitation of a boat, lay low in the mud; and a little squat shoal-lighthouse on open piles stood crippled in the mud on stilts and crutches; and slimy stakes stuck out of the mud, and slimy stones stuck out of the mud, and red landmarks and tidemarks stuck out of the mud, and an old landing-stage and an old roofless building slipped into the mud, and all about us was stagnation and mud.
