hat of cutting out or turning, and is performed in the following manner:--The turner, after fixing a piece of the nut in the chuck of his lathe, brings a tubular cutter, the face edge of which is toothed like a saw, to work on the exposed front surface of the nut; the result is that of a rough button or mould. As these moulds are rough, they are passed on to another lathe, where they are made smooth, and then to a third, where the holes are drilled. They are next passed on to the dyer, who arranges his colours according to instructions received. It sometimes happens that a mottled appearance is required; when such is the case, girls are employed to touch them with the colours required by the aid of camel-hair pencils. The buttons are next placed in tanks for drying, the tanks being heated by steam for that purpose. Most of the buttons are polished in lathes by friction from their own dust, held in the hand of the operative. Porcelain buttons were invented by Mr. R. Prosser, of Birmingham, who, in conjunction with the celebrated firm of Minter and Co., made them in large quantities in the potteries, about the year 1840. They were, however, soon driven from the market by French manufacturers, who sold a great gross--that is, twelve gross, each of twelve dozen--for the ridiculously small sum of elevenpence. Glass buttons are made by heating canes of glass and pinching them from the end with pliers, which at the same time answer the purpose of a die. They are sold very cheaply, as low as twopence a gross, but it is scarcely possible for any English firm to compete with Bohemia in their production. Mother-o'-pearl buttons are made out of pearl shells which have been imported from the coasts of Macassar, Manilla, Bombay, the archipelago of the Pacific, the Bay of Panama, and a few other places. Their market value is not always the same. At the present time it ranges from L8 to L10 per hundredweight. The blanks are cut out of the shells by a steel tubular cutter, similar to that used in cutting the vegetable ivory. As the cutter works its way through a shell, small cylinders of pearl are disconnected, which are reduced in thickness by splitting into discs, a little thicker than the button is required to be when finished. These blanks are finished singly in a turning lathe, by being placed in a suitable chuck, and having a steel tool applied to its face for producing the rim and depression in the centre. They are then pa
