If the institution became popular, books would have to be kept, corresponding to these glass cases--one book for cooks, another for housemaids, and so on; but the cases should never be given up. There should always be as many as the room will hold. Ladies should pay a certain sum for each servant they obtain; and the servant should pay for every place she gets, at a rate proportioned to the wages received. In most intelligence offices, the servants get two places for the same fee, if they do not stay over a week in the place, and the lady gets two girls or more on the same condition. This works like a premium on change of place. The servant should prove to the Labor Exchange, that she did not leave her place of her own will, and the lady should show that incapacity or insubordination made it impossible to keep her. It should be a cash business, and a fee should be paid for each application. Wanting a cook, you go down to the room, and consult the proper frame. Finding, perhaps, forty posters, you select one that reads like this:-- Matilda Haynes. Irish. Twenty-five years of age. In the country four years. Thoroughly understands plain cooking. Expects two dollars. Is willing to go out of town. Lived last at No. 4, Pemberton Square. Kept the place six months. May refer to it. Can be found at 24, High Street. You first go to Pemberton Square. It is quite possible that this girl may not be what you want; but if she is, and your eye tells you that you can trust the judgment of her referee, you have only to go to High Street, and make your own terms. If you are already prejudiced in her favor, you will go prepared to make some concessions, so that the chance will be better for you both; and this process may be repeated without loss of time, till you are supplied. You will see that this is quite a feasible plan, and has two advantages. One is, that you have access to the books, and can choose for yourself; the other is, that there would be no waiting-room for servants, where they should talk with, prejudice, and morally harm each other. You would also be saved the pain of rejecting servants to their faces, on the ground of "greenness," or bodily unfitness. Such an institution would offer this advantage over the present offices, that it would direct you to temporary laborers, and give you in a moment the addresses of some dozens. Such an institution would be a very great saver of time, and so a great blessing.
