Since 1922, generations of lawyers & surveyors have worked out the legal pitfalls of retracing original surveys & reestablishing lost & obliterated corners using the late Frank Emerson Clark's classic work A Treatise on the Law of Surveying & Boundaries. The Seventh Edition of Clark on Surveying & Boundaries maintains the proven, easy-to-use format of earlier editions while digesting the latest case law, regulations, & statutes. Cited in decision after decision, Clark on Surveying & Boundaries is recognized by surveyors & lawyers as the authoritative reference on surveying & subdividing public lands.
