Preface 



in the study of a single division. Evolution shows how 

 these branches are tied together in one harmonious plan. 

 It is not given to any one mind to possess a perfect knowl- 

 edge of all of these branches and their relation to one 

 another but, nevertheless, they furnish a never-ending 

 stream of reflective thought that opens up vast avenues of 

 understanding that lead to higher Culture. 



This book is not intended to be a learned treatise on 

 Evolution. It is meant to be an introductory study — an 

 outline, in the mysteries and harmonies of Nature^ s laws. 

 It is written by a layman for the laymen. If it has added 

 one new thought to Cultural Evolution, its purpose has been 

 accomplished. CHAS. W. GRIMES.
