Chewing-gum, a preparation the use of which has become a widespread habit in the United States. It is made from a gum called Chiele, produced by a Mexican tree allied to the india-rubber tree, and first imported in 1867 with a view to its employment in india-rubber manufacture. The gum is sweetened, and may be flavoured with peppermint, liquorice, tolu, or other flavouring substances, and is now supplied by automatic boxes at railway stations and other public places.
