while. As soon as the bulb has attained a certain size, he opens the mould with his left hand and encloses the bulb. Blowing is then continued until the glass touches the mould at all points, when the mould is opened and the bottle removed and broken off at the neck. In "burst-off" work the rough end is merely ground down on a stone after annealing. In "made" work a smooth finished and moulded end is formed in the following manner. An assistant, termed a "finisher," picks up the bottle in a "gauge"-- an iron bar with sheet-iron jaws at one end which fit the bottle-- and presents the neck to the furnace flames. When the end is red-hot and soft, he takes his seat in a kind of arm-chair and rolls the gauge backwards and forwards along the arms, shaping the neck with a pair of sugar-tongs with a central shaft of the same length between the two ends. The shaft terminates in a piece of brass, which is inserted in the neck to form the inside of the mouth; and the tongs carry brass squeezes to shape the outside when the tongs are squeezed against the glass by the finisher.
    The shaped bottle is lifted on a fork, and transferred to a "leer," or annealing oven. All glass
