Coming in from the eastward, the bright colouring of the [Nore] lightship marking the part of the river committed to the charge of an Admiral (the Commander-in-Chief at the Nore) accentuates the dreariness and the great breadth of the Thames Estuary. But soon the course of the ship opens the entrance of the Medway, with its men-of-war moored in line, and the long wooden jetty of Port Victoria, with its few low buildings like the beginning of a hasty settlement upon a wild and unexplored shore. The famous Thames barges sit in brown clusters upon the water with an effect of birds floating upon a pond... [The inward-bound ships] all converge upon the Nore, the warm speck of red upon the tones of drab and gray, with the distant shores running together towards the west, low and flat, like the sides of an enormous canal. The sea-reach of the Thames is straight, and, once Sheerness is left behind, its banks seem very uninhabited, except for the cluster of houses which is Southend, or here and there a lonely wooden jetty where petroleum ships discharge their dangerous cargoes, and the oil-storage tanks, low and round with slightly-domed roofs, peep over the edge of the fore-shore, as it were a village of Central African huts imitated in iron. Bordered by the black and shining mud-flats, the level marsh extends for miles. Away in the far background the land rises, closing the view with a continuous wooded slope, forming in the distance an interminable rampart overgrown with bushes.
