Page:Notes for mechanical drawing; arranged for the use of the students of the Mechanic arts high school and the Evening school of trades (IA notesformechanic00math).pdf/7

 The Notes for Mechanical Drawing are the results of twelve years experience in teaching high school and evening classes, arranged to cover the subject from a practical point of view suggested by the careful observation of the needs of these classes. The book is not a text-book, but is simply a collection of notes, exercises, and problems, to be used in connection with such explanation or demonstration as, in the judgement of the instructor, seems best suited to the classes.
