Figure No. 1. represents the mould in its entireness. No. 2, shows the interior of it (inverted). A is a thin metal plate which when turned downwards forms the bottom of the mould, and which is perforated in six places to permit the fluted columns B to pass through it. There is also a larger aperture in the middle to admit the centre cylinder. The plate is fixed, and the whole is held in its place by the part which folds over the larger scallop D at either end. There is also a cover which fits to the mould, and which is pressed on it before it is dipped into water, to prevent its getting into the cylinders.
