Chapter 6 GROWTH OF THE FIELD OF INVENTION

The following pages concisely show the marvelous growth of the Field of Invention from Primitive Man's Three Fundamental Wants, namely, Food, Clothing and Shelter, to the present-day countless necessities of Twentieth Century life. The same marvelous broadening of the field is found in all directions. The few illustrations given on the following pages will illustrate the point, and direct the thoughts of the student unerringly to the almost illimitable sphere of invention.
