PLAYING MARBLES, are mostly imported from Holland; where it is said they are made by breaking the stone alabaster, or other substance, into pieces or chips, of a suitable size; these are put into an iron mill which turns by water: there are several partitions with rasps within, cut boat-wise, not with teeth, which turn constantly round with great swiftness; the friction against the rasps makes them round, and as they are formed, they fall out of different holes, into which size or chance throws them. They are brought from Nuremberg to Rotterdam, down the Rhine, and from thence dispersed over Europe.
