Preface
This book is presented to those, both young and old, who wish to have a non-technical account of the history, evolution and production of some of the every-day wonders of the modern industrial age; coupled with occasional glimpses of the wonderful object-lessons afforded by nature in her constructive activities in the animal, vegetable and mineral kingdoms; and simple, understandable answers to the myriad puzzling questions arising daily in the minds of those for whom the fascination of the “Why” and “How” is always engrossing.
