Excerpt from A Manual of Mechanical Drawing It is the belief of the writer of this work that a pupil who has mastered the several lessons in their regular order will be able to read any drawing, and further, that he will be capable of making the usual run of drawings that come up in the repair shop, and, in fact, in many of the larger works. It is not the object of the writer to train designers. That would be out of the question, as designing calls for a wide range of knowl edge based upon experience, whereas drawing is purely mechanical, and based upon certain unvarying laws. Some draughtsmen will turn out better work than others. This comes partly from practice, and is in many cases due to a natural aptitude in the manipula tion of the instruments.
