[INTRODUCTION.]
The wise man learns from the experience of others. That is the reason for this introduction—to tell the boy who wants to make the toys described in this book some of the "tricks of the trade." It is supposed, however, that he has had some instruction in the use of tools.
This book is written after long experience in teaching boys, and because of that experience, the author desires to urge upon his younger readers two bits of advice: First, study the drawing carefully,—every line has a meaning; second, printed directions become clearer by actually taking the tool in hand and beginning to do the work described.
