In the first half basically EoC explains the principles of natural horsemanship and his way of working (very inspired by John Lyons). The second part of the book is devoted mainly to the 'Lesson 1': man-horse relationship (respect), basic work free hand and then in the saddle. The exercises are broken down and each step illustrated pictures. The purpose is accessible and applicable to all. This is especially exercise walk in the round pen.
This book is, I think, very useful to anyone who will take over the basic education of the horse: respect, calm, emphasized, session by hand.
Volume II is really dedicated to cleaning the first day of work life on the flat.
