A name that would more nearly indicate the contents of this book to American readers would be:- "The Metal Working Lathe," as the entire volume is devoted to that tool. For this reason, the treatment of the subject is much more complete than with books treating of all the tools of a shop. The author is well known to readers of technical books as a skilled writer, and this book fully equals, and in some respects surpasses, its predecessors. Anyone desiringto know lathe work in all its branches will find this book of the greatest value, as the illustrations are numerous and well drawn and the text clear and practical.

The book is divided into six sections, the first giving a full description of the lathe and its parts, including the special features peculiar to lathes of both American and English make. The second section treats of turning between centers, and section three takes up work supported at one end. In section four internal work is fully described, and section five covers screw cutting and turret work. The closing section includes miscellaneous matters, such as grinding, tool holders, speeds and feeds, tool steels, etc.

The above brief mention of the contents is sufficient to show how great a help the book would be to the apprentice, although its value is almost equally great for the regular lathe hand who desires to learn the most approved methods of turning out work. For teachers of metal working in manual training schools the book cannot be too highly commended.
