There are black books in the great dressmaking establishments and queer things are entered in them, items of information that would furnish spicy running commentary upon Parisian life. The incomes of Monsieur's customers are so often fluctuating things. Even in the beau monde there may be circumstances not generally understood, and, where no touch of scandal enters into the calculations, still there is room for mistake. Fortunes may rest on tottering foundations, appearances are often misleading. Yes, there is much to confide to the black book, and the dressmakers interchange statistics in right comradelike fashion. There are men employed whose business it is to investigate all matters having a bearing upon the financial condition of the women who make up the clientèles of the famous dressmakers, and it might surprise some of the gay butterflies that flutter into the luxurious salons of the dressmaking establishments to know how thoroughly informed concerning their private affairs are the saleswomen who wait upon them and the "master" who caters to their whims.

The saleswoman is as clever in dealing with Miss Millions from Chicago as with the irrepressible Toinette. She flatters so subtly, influences so insensibly, makes herself so indispensable. Madame must never be made to feel that her own taste is bad, but she must, if possible, be guided to wise selection, persuaded to believe that she herself has decided upon the frock she finally chooses. It is to the interest of the house that every woman who buys her frocks there should look her best. Moreover, the woman whose friends praise her clothes will hold fast to her dressmaker, so the saleswoman does her best, and unless the customer is very obstinate, that best is surprisingly good. If necessary, with an old and valued customer the diplomat can be firm, suavely, politely firm.

"Why have I no black gown on the list?" asks Madame, after studying the plan of her season's outfit as made out by Mademoiselle Therèse.

Mademoiselle smiles, a deprecatory little smile, but her reply is prompt.

"We find that this year Madame is not of an age to wear black," she says simply, sweetly, but with a finality in her tones.

Madame colours, looks resentful, Mademoiselle busies herself with orders to a mannequin. The pause is ended by a sigh of resignation.

"Oui, c'est vrai," admits Madame. "There is an age, and there is again an age, but in between—eh, bien, it is true. We must now be careful, Therèse."

The successful saleswoman gains the confidence of her customers, holds them, brings millions of francs' worth of business to her employer, and receives a commission on all sales. One saleswoman, among the best in her class, makes as much as fifteen thousand dollars a year out of her commissions, and, though this is exceptional, all earn good incomes.

The mannequins or models are the secondary features of the "front"; but they are of little importance compared with the saleswomen; and while it is a difficult thing to replace a good saleswoman, satisfactory mannequins may be had for the asking.
