We hear a great deal about the conservation of our natural resources such as forests and waterways it is hoped that this book will show
the vital importance of the conservation of human strength and health and the irreparable loss to society of energy uselessly dissipated
either in idle worry or in aimless activity. Most of us would reproach ourselves for lack of shrewdness if we spent for any article more thanit was worth yet few of us consider that we daily expend on domestic and business tasks an amount of energy far in excess of that actually
required. The farmer who flails his grain instead of threshing it wastes time and energy the housewife who washes with her hands alone
and does not aid herself by the use of washing machine and proper bleaching agents dissipates energy sadly needed for other duties.
