Marbles. You may tell your boys that the marbles with which they play are mostly imported from Holland, where they are made by breaking various kinds of stone into pieces of a suitable size; these pieces arc put into an iron mill, worked either by water or steam ; there are several divisions in the mill, with rasps, which turn round with great swiftness; thus they are made round, and then they fall out of the mill. They are brought from Nuremburg to Rotterdam, down the Rhine, and from thence distributed over America, The " allies" are cut from superior marble.
