EDITORS' PREFACE 



somewhat older, and students of whatever age will 

 find it instructive and suggestive. Whoever delights, 

 with Kepler, to ''read God's thoughts after Him" 

 discovers in a reverent study of nature food for mind 

 and spirit. In the pursuit of the infinite and eternal 

 forces and processes, differences of a few years cease 

 to be of importance, and the student finds himself, 

 in Higginson's fine phrase, of the age of everybody. 

 If this book helps our children to enter into the treas- 

 ures of the world, to see everywhere in earth and sky 

 reminders of divine power and love, and to tread the 

 earth habitually with reverent feet, the purpose for 

 which it has been prepared, as of the Course of which 

 it is a part, will have been accomplished. 



The Editors.
