Acquire Their Good Ilreedîngî Froni Earliest Chi1dâhood. The reason that the French peo- pie en joy the well earned reputa- tion of being tne poiitest peoplel in the world is because, "la1 politesse," or good hreeding, is an j accompiishment they always ac- ruire at home and in chilhood. A Frenchman, his wife, and a couple of children will observe ail the most 3xquisite social amenities in the privacy of their own home, and the family life presents ail the social advantages they require. A Frenchi boy of even the humblest parentage does not wait to go out in the world te learn how to offer a woman a chair, give an elderly gentleman his arm, invite you to dine, or dis- cover the topies of conversation that engage your interest. Ho has Iived £rom. his babyhood in an atmosphere of family deference and cheerfuI. unselfish considera- tion, and he is charrningly polite by precep3t and example wherever he May find himself.
