This book is the outgrowth of problems given to high school pupils by
the writers, and has been compiled in logical sequence. Stress is laid
upon the proper use of tools, and the problems are presented in such a
way that each exercise, or project, depends somewhat on the one
preceding. It is not the idea of the writers that all problems shown

them for other models following.

The related matter on the care of the lathe and tools, the grinding of
chisels, the polishing of projects, and the specific directions and

drawings, make the book not only valuable for reference, but also as a

drawings show exact dimensions and are tabulated in the upper right-hand
corner in such a way that they may be used in a filing case if desired.
At least two designs are shown for each model, and these may be used as
