Conversation with family and intimate friends is somewhat in danger of becoming a little too informal, too laconic. Sometimes we take our own folks too much for granted. At its best, however, this is the acme of conversation, carrying the fullest meaning with least effort. -from "Social Conversation" This classic of developing confidence and poise when talking to absolutely anyone is full of sound, solid advice that is just as useful today as it was when it was first published in 1928. Two experts in public speaking-and private conversation-cover the full range of interpersonal communication: . at work: how to talk to your boss and your subordinates . in civic situations: how to communicate effectively at club and committee meetings . at home: how to enjoy personal conversations more . in public: giving a lively speech. The authors promise no "magic formula," just graceful guidance for becoming a more thoughtful and resolute speaker. JOHN MANTLE CLAPP (b. 1870) also wrote Doing Business by Letter and Language for Men of Affairs. EDWIN A. KANE was an instructor in public speaking at the College of the City of New York.
