It is desirable for a music seller to understand Italian, French, and German, as many of the songs used in our country are in those languages. Many pieces of music have two or three titles. It requires some time to learn to rightly perform the duties of a music seller. The selling of sheet music and the selling of pianos are separate branches, and a person in one may be totally ignorant of the other. The wholesale and retail departments are entirely distinct in large establishments. Clerks that attend in the piano department are expected to be able to play. A lady is now employed in a large piano store in New York to try the instruments for purchasers. A lady in New York stays in the store when her brother, Mr. D., is absent. He paid a boy $1.50 a week for some months while learning, then more. A person of ability could learn the business in six months' time, or less. Music is always arranged alphabetically on the shelves. A boy should be kept to climb the ladder. An extensive music seller in Boston writes: "In our direct employ is only one female--a cashier. Repeated losses of money, and cash continually over or above, induced us four years ago to adopt the plan of employing a female to receive the proceeds of sales. It has saved us a great deal of money, and lessened the temptation to the young men in the store. We would gladly employ more women, but the height of our shelves, and the unsuitableness of female apparel, prevent." Another music seller writes me: "Women are employed in our business, in Germany and France, and are there paid at the same rate as men. We do not employ ladies in our store, because those of their own sex will not buy from them." =111. Sellers of Artists' Materials.= The sale of paintings, engravings, and artists' materials, form of themselves a branch of business in large cities. I know of such a store in Philadelphia, kept by a lady. It must be a light and pleasant employment. In London there are seventy-nine print sellers.
