Excerpt from Mechanical Drawing for Secondary Schools This book analyzes mechanical drawing upon the basis of its elements, or natural divisions, such as Perspective Sketch ing, Orthographic Sketching, Pencil Mechanical Drawing, Ink ing, Tracing, and Reproducing. Each one of these divisions is treated separately in a chapter. Each chapter organizes the division of drawing which it represents. Hence in each chap ter there is presented a progressive series of problems in one of the natural divisions of the subject. The book contains six chapters and covers the first two years of mechanical drawing in Secondary Schools. The first four chapters are designed to occupy the time of a class for the first year of the two years' course. As there is a large element of exibility in the selection of problems, no one Individ ual is expected to solve all problems. The course may be easily extended over a period of more than two years, even to three or four years, depending upon the number of problems solved, whether a part or all of the chapters are included in the course, and the time devoted to the subject during each year.
