The book contains only three pages with text, one of which I chose to upload. I assume it`s an introduction or short summary. The writing is rather small, and the page is extremely packed but nevertheless the author insists to use enough space to place a drawing to decorate it. Between each printed page the author makes sure to place an empty sheet for the reader to write down his own thoughts or sketch his own observations, I assume. The third page is one of the many drawings in this book. I specifically chose this one because I can`t actually tell what it is that is being portrayed (…some sort of ground-plan or cut).
