PREFACE 



The present volume consists of a collection of Essays 

 and Addresses which have appeared at intervals since 

 the publication of my Geological Essays at Home and 

 Abroad. Half of them deal with Scenerv in its 

 geological relations and in its influence on human 

 progress — a subject which for many years has en- 

 grossed much of my thought. Others discuss the 

 problem of the Age of the Earth, while two are 

 biographical, and one deals with the place of Science 

 in modern education. 



I have to thank the editors of the Fortnightly, Con- 

 temporary, and International Quarterly Reviews for their 

 courtesy in readily according me permission to reprint 

 the essays which have appeared in these publications. 



I yh January, 1905.
