While preparing for my licensing exam, I read this book from cover to cover. It addresses every principle of retracement (sequential and simultaneous conveyances), public lands, and riparian issues thoroughly. The highlighted "principle" at the heading of each new topic makes remembering the main points simple. I can honestly say that every question on the NCEES exam that dealt with general principles and practice was answered in this book. I passed on my first sitting, and this book was one of the main reasons why. If you can only study one reference, this is it. Every practicing surveyor should also refer to it regularly.
