THE series of exercises given in this text is the result of the author's experience in teaching turning. Each model has been developed for the purpose of teaching a correct use of the tools, so that pupils can do excellent work without the long drill to acquire skill or the necessity of scraping where cutting tools should be used. If turning lathes are to be used in the school, they should be used properly. It is the hope of the author that this manual will aid such instructors as are trying to teach a rational method of turning.

A careful examination of the text by one who understands this line of work will reveal the fact that the elementary principles are covered very completely, and yet there is not in the regular set a single exercise which may be dispensed with, without a real loss to the average pupil.

The numerous illustrations are not only to make clear a way in which to do the work, but to furnish such a variety of similar views that the pupil will be certain to draw comparisons and to form an individual method of work.

Although a proper study of this book will result in a marked degree of proficiency in turning, yet the greater benefit will be the training which comes from the constant and careful attention required to do this work. The aim is not technique, but power — mental growth.

Several of the models were suggested by those used in other schools. The general arrangement and method of treatment are entirely original with the author.

But few woods are mentioned in the text. In fancy turning a variety of woods should be used, if they can be obtained. The instructor should see that each pupil acquires some knowledge of both local and foreign woods'.
