=64. Music Engravers and Folders.= Mr. L. engraves and prints music, and employs two ladies to fold it. There are but few music engravers. The smaller the number of persons in any one kind of business the higher the prices they can command. A lady in New Orleans engraves, whose husband is a music printer. It would require but two or three years to learn it. Some ingenuity, a knowledge of the value of notes in music, and judgment in the arrangement of them are necessary to make an engraver. In New Orleans, eight months are usually considered a year, I believe, in business arrangements. At a music engraver's the young man told me that he never heard of a woman engraving music in this country, but he knows that some do in Paris. The work they turn out, he added, is not good; it will not wear, because women have not sufficient strength in the wrist to engrave as deeply as a man. A person who engraves plates for music can earn from $3 to $5 a day. German work is considered the best, because the quality of the ink used is better. Music engraving is divided into two distinct branches--one is lettering and engraving the title page--the other is engraving the notes. No steam machinery has ever been invented for printing music, because the ink must all be put on the way the work is done. Music is one of the first things dispensed with in hard times.
