The 39 projects consist of a single page of plans, not exploded diagrams with step-by-step as in modern how-to, with a list of parts to cut, and a short commentary on particular problems. The most complicated have two pages of plans with two pages of remarks and "Bill of Material" (parts list). Originally copyrighted in 1931, this has been reprinted by the likes of Bonanza Books in recent years. This book was designed for the trained home woodworker and for the teacher of advanced wood shop classes at vocational high schools. The projects are called "problems" for classrooms, and are designed to challenge students as they increase in skill, though the book itself does not teach the skills: turning on the lathe, cutting mortise & tenon joints, etc. Even where he gives rudimentary instructions on making rush seats, he suggests getting a book on chair seating.
