The Potsdam square, always disfigured by city work (oh, those old postcards of it where everything is so spacious, with the droshki drivers looking so happy, and the trains of tight-belted ladies brushing the dust—but with the same fat flower-girls). The pseudo-Parisian character of Unter-den-Linden. The narrowness of the commercial streets beyond it. Bridge, barge, sea gulls. The dead eyes of old hotels of the second, third, hundredth class. A few more minutes of riding, and there was the station.
