The best kind of a "dabster" is made from a mole's skin. The common marbles used by boys everywhere are called mibs, fivers, commies, migs, megs, alleys, and dubs. A very large marble is a bumbo and a very small one a peawee. Glass marbles are called crystals and those made of agate are called reals. The choicest real is supposed to be green and is called a "mossic" or "moss real."
