Book excerpt: Excerpt from Elements of Mechanical Drawing: Use of Instruments, Geometrical Problems, and Projection IN the preparation of this book, and others of the technical drawing series, it is the aim of the author to provide text-books rather than copy-books; treatises in which principles should be established, and methods suggested, but freedom permitted in their application. While the treatment of much of the subject is new, it has long since passed the experimental stage, and nothing is here published that practical experience in the class-room has not justified. The third angle OF projection is used exclusively, as is required in all good practice, and the terms top and front view have been substituted for plan and elevation by reason of the confusion arising from the use of the latter. The methods employed for the representation of objects oblique to the planes of projection have been found to give a clear and comprehensive understanding of a subject which is usually much encumbered with rules, soon to be forgotten. The introduction of a graphic statement of problems relieves the instructor of the mechanical and frequently laborious, task of devising suitable problems, with proper dimensions, and enables the student to begin the drawing Without delay. The treatise on screw-threads and Bolts is the embodiment of instruction and problems given to classes during the past six years, and is an introduction to the study of machine drawing, as treated in the second book of the series. It is intended that the student should first thoroughly master the principles, and then, un aided apply them to the solution of the problems, receiving such instruction as his special case may demand. By this means, individual instruction may be given to large classes, and the energy and talent of the teacher directed to the giving of instruction, instead of performing the petty details of devising problems, etc. It also enables the more competent student to advance, inde pendent of the progress of those who may require more time.
