Moreover, all lovers have the art of arranging a special code of signals, whose arbitrary import it is difficult to understand. At a ball, a flower placed in some odd way in the hair; at the theatre, a pocket handkerchief unfolded on the front of the box; rubbing the nose, wearing a belt of a particular color, putting the hat on one side, wearing one dress oftener than another, singing a certain song in a concert or touching certain notes on the piano; fixing the eyes on a point agreed; everything, in fact, from the hurdy-gurdy which passes your windows and goes away if you open the shutter, to the newspaper announcement of a horse for sale—all may be reckoned as correspondence.
How many times, in short, will a wife craftily ask her husband to do such and such commission for her, to go to such and such a shop or house, having previously informed her lover that your presence at such or such a place means yes or no?
On this point the professor acknowledges with shame that there is no possible means of preventing correspondence between lovers. But a little machiavelism on the part of the husband will be much more likely to remedy the difficulty than any coercive measures.
An agreement, which should be kept sacred between married people, is their solemn oath that they will respect each other's sealed letters. Clever is the husband who makes this pledge on his wedding-day and is able to keep it conscientiously.
In giving your wife unrestrained liberty to write and to receive letters, you will be enabled to discern the moment she begins to correspond with a lover.
But suppose your wife distrusts you and covers with impenetrable clouds the means she takes to conceal from you her correspondence. Is it not then time to display that intellectual power with which we armed you in our Meditation entitled Of the Custom House? The man who does not see when his wife writes to her lover, and when she receives an answer, is a failure as a husband.
The proposed study which you ought to bestow upon the movements, the actions, the gestures, the looks of your wife, will be perhaps troublesome and wearying, but it will not last long; the only point is to discover when your wife and her lover correspond and in what way.
We cannot believe that a husband, even of moderate intelligence, will fail to see through this feminine manoeuvre, when once he suspects its existence.
Meanwhile, you can judge from a single incident what means of police and of restraint remain to you in the event of such a correspondence.
A young lawyer, whose ardent passion exemplified certain of the principles dwelt upon in this important part of our work, had married a young person whose love for him was but slight; yet this circumstance he looked upon as an exceedingly happy one; but at the end of his first year of marriage he perceived that his dear Anna [for Anna was her name] had fallen in love with the head clerk of a stock-broker.
