Excerpt from Progressive Carpentry: Together With a System of Framing Roofs
It has long been the purpose of the author to present to the public his system of constructive carpentry, viz.: the plumb and level line system, by which all bevels and cuts may be obtained for any form of frame work, without the necessity of making extra drawings for that purpose, as required in other methods.
The work of preparation for this book was begun over thirty-five years ago. During the interval, many important improvements were discovered and also incorporated in the work, finally published under the title of Progressive Carpentry.
The book met with a very favorable reception, selling through several editions. In the meantime the author developed some new examples of frame work of various kinds, especially of truss roofs for large buildings and churches, and for bridges. These trusses were thoroughly tested and proven to be satisfactory. (See pages 52 to 89.)
The author"s ambition is gratified in having presented so acceptable a book on methods of construction, and he trusts that these additions will render it still more useful. Progressive Carpentry has undoubtedly helped many enterprising mechanics to earn better wages and, it is believed, will be of like advantage to thousands who have yet to study its simple and reliable methods.
