A practical manual for public speaking that explains how to strengthen projection and vocal resonance and how to craft an effective opening that eases an audience into the subject. It recommends pacing and energy management so material builds rather than flags, and outlines lecture structure from exordium to peroration. The work gives advice on selecting and preparing subjects, organizing course lectures, and avoiding distracting mannerisms. Additional sections cover the role of the chair, debating tactics, rhetorical technique, adapting style to different audiences, street-speaking logistics, handling interruptions and police, and ethical methods for promoting and selling books at meetings.
