Query: Best book on grammar combined with sentence diagramming.

I have read and used several books on diagramming. This book is the best I have seen so far. The grammar section at the beginning is thorough. The author even has a quick page on parsing. The text and layout make the book easy to read and use. Everything I have to say is positive. Diagramming with this book's help is an amazing method to see language as more than words thrown together.I also recommend Rex Barks for additional practice and another way to look at parts of speech. Everything a squirrel can do to a tree is a great way to remember prepositions. Sister Bernadette's Barking Dog makes a nice introduction to diagramming and discusses the history of diagramming, but doesn't really teach it.
