This book, like its companion volume, Elements of Drawing by the same authors, is based on the work of this character required of all first-year students inS ibley College, Cornell University. It is the outgrowth of an effort to modify and shorten somewhat the scope and method of presentation of this subject, from the lengthy discussion often presented, to one more in keeping with the relative importance of the subject in an engineering curriculum. This work was undertaken for me some years ago by Professor Blessing, and the book is the outgrowth of a series of lectures and an accompanying drawing-room course first given by him and later continued by Professor Darling; both being at the time members of the instructing staff of theD epartment of Machine Design and Construction of Sibley College. The work of putting this material into the form of a book was undertaken by the authors at the writers request, the object in view being twofold, namely: to obtain a book exactly suited to the needs of theD epartment, which we had hitherto been unable to do, and also to put into permanent shape the methods and principles used in this work, thus forming one of a series of correlated textbooks which eventually it is expected will cover the entire work of theD epartment. The authors brought to the task a full knowledge of the more advanced work of theD epartment, having had experience in teaching the advanced subjects in design, which with their experience elsewhere both in practical and teaching positions was of great aid in improving and simplifying this more elementary work.(Typographical errors above are due to OCR software and don't occur in the book.)About the Publisher Forgotten Books is a publisher of historical writings, such as: Philosophy, Classics, Science, Religion, History, Folklore and Mythology.Forgotten Books' Classic Reprint Series utilizes the latest technology to regenera
