After all, in a very little time everything that impresses me so mightily this September afternoon will have changed or passed away for ever, everything. These omnibuses, these great, stalwart, crowded, many-coloured things that jostle one another, and make so handsome a clatter-clamour, will all have gone; they and their horses and drivers and organisation; you will come here and you will not find them. Something else will be here, some different sort of vehicle, that is now perhaps the mere germ of an idea in some engineer student's brain. And this road and pavement will have changed, and these impressive great buildings; other buildings will be here, buildings that are as yet more impalpable than this page you read, more formless and flimsy by far than anything that is reasoned here. Little plans sketched on paper, strokes of a pen or of a brush, will be the first materialisations of what will at last obliterate every detail and atom of these re-echoing actualities that overwhelm us now. And the clothing and gestures of these innumerable people, the character of their faces and bearing, these too will be recast in the spirit of what are now obscure and impalpable beginnings.
