Excerpt from A Practical Course in Mechanical Drawing The subject is best taught with the use of models, instead of sketches and pictorial illustrations. A glance through the book will convince the teacher that a set of models corresponding to the exercises can be easily procured. The result of the instruction will then' be real instead of imaginary, since the student knows absolutely what his drawings represent, and need not rely on an untrained imagination.
