=292. Pearl Workers.= At S.'s, we saw a man grinding the outer and rougher coat off of pearl shells. It requires some strength, as it is done on a stone wheel moved by steam, the shell being kept in its place by a wooden rod held on it. It is wet and dirty work. The water is cold, too, even in winter, for warm water would soon become cold on account of the rapid motion of the wheel; and it would not do to heat the pearl, as it would cause it to split. The polishing was done on a wheel covered with leather, and could as well be done by a girl as a boy. S. had never known women to work in pearl, except to make paper cutters, and then only in Germany. The inlaying of pearl is in some places done by women. A worker in pearl writes me: "The pearl button branch is separate from the pearl shell work. In the first, females are employed; in the latter, they are not, as it is unhealthy and laborious. In Birmingham, England, where pearl buttons are almost exclusively manufactured, upward of two thousand hands are employed. Pearl buttons are made in Newark and Philadelphia." A manufacturer of pearl buttons in Philadelphia writes: "I employ women in finishing, and pay from $2 to $3 a week. It requires from one to three weeks to learn. The prospect of the business increasing is good. The work is regular, and the hours ten a day. I employ women because they are cheaper." To polish pearl buttons is very simple--merely placing the button in a pair of tongs, and holding it against three revolving wheels successively. The carving of pearl is wrist work, and S. thought women have not sufficient strength in their wrists to do it; but I think many have. TORTOISE-SHELL WORKERS.
