Excerpt from A Course of Study in Industrial Drawing: An Elementary Manual for the Self-Instruction of Teachers and Pupils of Public and Private Schools In the practice of my profession as a teacher of industrial drawing, it has been my custom for many years, to select from all sources What I thought most appropriate for my pupils. As a result, I found myself engaged in a course so different from any already published, that I was compelled to write this book for use in the schools under my supervision. Although the materials selected are old, the manner of hand ling them Will be found to be quite my own. Every example has been thoroughly tested in the school room and proven satisfactory, not only When in the hands of the special instructor, but also When used by the regular teachers. This is really a revised and enlarged edition of my work upon the same subject published last year. Several years of practical draughtsmanship in architectural and engineering offices, and a long and varied experience as a teacher in all the grades and classes of the public schools, have shown me the need of a drawing manual to meet the in creasing demands for a practical education, so large a part of Which education lies in the knowledge of industrial drawing, a study so necessary and yet so little understood by my fellow teachers and the public generally.
