“A correspondent from the city of Boone, Iowa, sends $5 and some sketches of a table he is building, evidently intended for some gambling establishment. There is a plate of soft iron in the middle of the table under the cloth, which by an electric current may become magnetized. Loaded dice can thereby be manipulated at the will of the operator. He desires us to assist him in overcoming some defects in his design. We have returned the amount of the bribe offered, and take the opportunity of informing him that we do not care to become an accessory in his crime.”
