"Between the crowded houses of Gravesend and the monstrous red-brick pile on the Essex shore the ship is surrendered fairly to the grasp of the river. That hint of loneliness, that soul of the sea which had accompanied her as far as the Lower Hope Reach, abandons her at the turn of the first bend above. The salt, acrid flavour is gone out of the air, together with a sense of unlimited space opening free beyond the threshold of sandbanks below the Nore. The waters of the sea rush on past Gravesend, tumbling the big mooring buoys laid along the face of the town; but the sea-freedom stops short there, surrendering the salt tide to the needs, the artifices, the contrivances of toiling men. Wharves, landing-places, dock-gates, waterside stairs, follow each other continuously right up to London Bridge, and the hum of men’s work fills the river with a menacing, muttering note as of a breathless, ever-driving gale. The water-way, so fair above and wide below, flows oppressed by bricks and mortar and stone, by blackened timber and grimed glass and rusty iron, covered with black barges, whipped up by paddles and screws, overburdened with craft, overhung with chains, overshadowed by walls making a steep gorge for its bed, filled with a haze of smoke and dust."
