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
should be made, but that the instructor select only such as will give
the pupils enough preliminary work in the use of the tools to prepare
them for other models following.
