Let us hope that your espionage will not give you so troublesome a lesson. Such misfortunes are the fruits of the civil war and we do not live in that age. 4. THE INDEX. The Pope puts books only on the Index; you will mark with a stigma of reprobation men and things. It is forbidden to madame to go into a bath except in her own house. It is forbidden to madame to receive into her house him whom you suspect of being her lover, and all those who are the accomplices of their love. It is forbidden to madame to take a walk without you. But the peculiarities which in each household originate from the diversity of characters, the numberless incidents of passion, and the habits of the married people give to this black book so many variations, the lines in it are multiplied or erased with such rapidity that a friend of the author has called this Index _The History of Changes in the Marital Church_. There are only two things which can be controlled or prescribed in accordance with definite rules; the first is the country, the second is the promenade. A husband ought never to take his wife to the country nor permit her to go there. Have a country home if you like, live there, entertain there nobody excepting ladies or old men, but never leave your wife alone there. But to take her, for even half a day, to the house of another man is to show yourself as stupid as an ostrich. To keep guard over a wife in the country is a task most difficult of accomplishment. Do you think that you will be able to be in the thickets, to climb the trees, to follow the tracks of a lover over the grass trodden down at night, but straightened by the dew in the morning and refreshed by the rays of the sun? Can you keep your eye on every opening in the fence of the park? Oh! the country and the Spring! These are the two right arms of the celibate. When a woman reaches the crisis at which we suppose her to be, a husband ought to remain in town till the declaration of war, or to resolve on devoting himself to all the delights of a cruel espionage. With regard to the promenade: Does madame wish to go to parties, to the theatre, to the Bois de Boulogne, to purchase her dresses, to find out what is the fashion? Madame shall go, shall see everything in the respectable company of her lord and master.
