On the morning when I left Rotterdam I saw in the streets through which I passed to get to the Delft railway-station a novel spectacle, purely Dutch--the cleaning of the houses, which takes place twice a week in the early morning hours. All the servants in the city, dressed in flowered lilac-colored wrappers, white caps, white aprons, white stockings, and white wooden shoes, and with their sleeves turned up, were busily washing the doors, the walls, and the windows. Some sat courageously on the window-sills while they washed the panes of the windows with sponges, turning their backs to the street with half their bodies outside; others were kneeling on the pavement cleaning the stones with rough cloths; others were standing in the middle of the street armed with syringes, squirts, and pumps, with long rubber tubes, like those used for watering gardens, and were sending against the second-floor windows streams of water which were pouring down again into the street; others were mopping the windows with sponges and rags tied to the tops of long bamboo canes; others were burnishing the door-knobs, rings, and door-plates; some were cleaning the staircases, some the furniture, which they had carried out of the houses. The pavements were blocked with buckets and pitchers, with jugs, watering-pots, and benches; water ran down the walls and down the street; jets of water were gushing out everywhere. It is a curious thing that while labor in Holland is so slow and easy in all its forms, this work presented an appearance altogether different. All those girls with glowing faces were bustling indoors and hurrying out again, rushing up stairs and down, tucking up their sleeves hastily, assuming bold acrobatic attitudes and undergoing dangerous contortions. They took no notice of those who passed by except when with jealous eyes it was necessary to keep the profane race away from the pavement and walls. In short, it was a furious rivalry of cleanliness, a sort of general ablution of the city, which had about it something childish and festive, and which made one fancy that it was some rite of an eccentric religion which ordered its followers to cleanse the town from a mysterious infection sent by malicious spirits. DELFT. On my way from Rotterdam to Delft I saw for the first time the plains of Holland.
