William Walton, author of Paris from the Earliest Period to the Present Day (published in 1899) writes:
Paris may be said to be a very well-policed city. The police regulations are intelligent, and cover all those points in which the safety, or comfort, or peace of mind of the majority of well-meaning citizens may be menaced or disturbed by the inconsiderate action of individuals, and yet these strict ordonnances, which might become harsh or tyrannical, are generally administered with discretion and, in the case, for example, of the peripatetic vendors of vegetables, the marchands and marchandes des quatre-saisons—with due consideration for the difficulties of the poor.
Great care is taken to assure the free circulation in the streets, with one very important exception: the householder must not deposit any garbage, or mud, or broken bottles on the sidewalk, he must wash his shop-windows only between certain hours in the morning, he must not beat nor shake carpets out the window nor in the streets, he must not put his flower-pots in the windows where there is any danger of their falling on the passer-by, he must not keep domestic animals in such numbers or of such a kind as to be disagreeable to his neighbor, he must not burn coffee, nor card the wool of his mattresses, on the public highway, and he must not set out chairs or tables on the sidewalk. This last regulation, however, is practically a dead letter, all the cafés, big and little, on the wide trottoirs of the boulevards and on the two-foot sidewalks of the narrow streets, monopolize from a half to three-fourths of the pavement for pedestrians. The latter file along cheerfully on the curb-stone, or turn out in the street altogether, and make no protest. In the poorer quarters, a great number of domestic occupations and maternal cares are transferred to the street in front of the dwelling; in fact, the fondness of the French for out-of-doors is one of their most striking characteristics. The women and young girls will sit sewing or knitting in the streets or the public parks, and the men at the open-air tables of the cafés, in the wettest and rawest of days, and the women of the lower orders, concierges, workwomen, small shopkeepers, etc., constantly go with their heads uncovered. This healthy hankering of all classes for the open air contrasts very strongly with their imbecile terror of fresh air, or courants d’air, in a closed vehicle or under a roof.
