Editors' Preface ix 



goes beyond our ascertained knowledge. But 

 faith must not operate apart from knowledge. 

 Nothing can be more important in religious 

 education than to train young people to use 

 the careful methods of science in ascertaining 

 the facts upon which their conclusions, not less 

 in morals and religion than in other fields, are 

 always to be based. The author of this volume 

 is a most successful teacher, and he has suc- 

 ceeded in presenting the technical aspects of 

 the subject in a simple and popular way. 



While the book has been prepared for young 

 people's classes, the editors would commend 

 it to the reading of ministers and laymen who 

 are desirous of obtaining in untechnical lan- 

 guage the results which scholars have arrived 

 at in this modern attack upon the problem of 

 evolution.
