Some considered thoughts on a ""major American industry"" --public speaking -- come from a veteran of many frays, on many fronts, before many people. This is not a how-to manual but a series of discourses on effective speech and communication which is truthful; on amateurs and professionals; on campaign and routine meeting oratory; on the participation of the audience at an intelligent level; on the trials and temptations confronting all types of speakers; on hostile hearers; on radio and TV. A last section decries public deafness together with the threat of conformity as an obstacle to free speech. A book of first interest to the more than occasional speaker, this holds many worthwhile observations and comments and offers many workable ideas; it makes the most, too, of his long experience in speechmaking before all kinds of audiences. Readable.
