All sorts of extraordinary shadows have come to me in the Parks, the Twopenny Tube, and along the Thames Embankment. At ten o'clock, on the morning of 1st April 1899, I entered Hyde Park by one of the side gates of the Marble Arch, and crossing to the island, sat down on an empty bench. The sky was grey, the weather ominous, and occasional heavy drops of rain made me rejoice in the possession of an umbrella. On such a day, the park does not appear at its best. The Arch exhibited a dull, dirty, yellowish-grey exterior; every seat was bespattered with mud; whilst, to render the general aspect still more unprepossessing, the trees had not yet donned their mantles of green, but stood dejectedly drooping their leafless branches as if overcome with embarrassment at their nakedness. On the benches around me sat, or lay, London's homeless--wretched-looking men in long, tattered overcoats, baggy, buttonless trousers, cracked and laceless boots, and shapeless bowlers, too weak from want of food and rest even to think of work, almost incapable, indeed, of thought at all--breathing corpses, nothing more, with premature signs of decomposition in their filthy smell. And the women--the women were, if possible, ranker--feebly pulsating, feebly throbbing, foully stinking, rotten, living deaths. No amount of soap, food, or warmth could reclaim them now. Nature's implacable law--the survival of the fittest, the weakest to the wall--was here exhibited in all its brutal force, and, as I gazed at the weakest, my heart turned sick within me. Time advanced; one by one the army of tatterdemalions crawled away, God alone knew how, God alone knew where. In all probability God did not care. Why should He? He created Nature and Nature's laws. A different type of humanity replaced this garbage: neat and dapper girls on their way to business; black-bowlered, spotless-leathered, a-guinea-a-week clerks, casting longing glances at the pale grass and countless trees (their only reminiscence of the country), as they hastened their pace, lest they should be a minute late for their hateful servitude; a policeman with the characteristic stride and swinging arms; a brisk and short-stepped postman; an apoplectic-looking, second-hand-clothes-man; an emaciated widow; a typical charwoman; two mechanics; the usual brutal-faced labourer; one of the idle rich in shiny hat, high collar, cutaway coat, prancing past on a coal-black horse; and a bevy of nursemaids.
